You can only have 1 web process type. You can horizontally scale your web process to run on multiple dynos ("horizontal scalability"), however you will need to upgrade to at least standard-1x dyno types to do that (i.e. you can only run 1 web dyno instance if you are using free or hobby dyno types).However, in addition to your web process, you can instantiate multiple additional process types (e.g. "worker" processes). These will NOT be able to listen on HTTP/S requests from your clients, but can be used for offloading long-running jobs from your web process.So, if you map each of your 4-6 microservices to a different Process Type in your Procfile, and if your microservices are not themselves web servers, you might be able to make do with hobby dynos.ShareFollowansweredMar 16, 2017 at 15:24Yoni RabinovitchYoni Rabinovitch5,21111 gold badge2424 silver badges3535 bronze badges3Ok.

I am creating small app running multiple microservices. I would like to have this app available 24/7, so free dyno hours are not enough for me. If I upgrade to ahobbyplan I would get10 Process Types.Can I run another microservice on each of the processes (web), or does Heroku give me the ability only to install one web process per dyno, and the other10 process typesare for scaling my app? In other words, If i need 6 microservices running 24/7 should I buy 6 hobby dynos?

In Amazon S3, thekeyis the object name, or file name if your objects are files. Thekeyis listed in the results when retrieving the contents of the bucket, and you retrieve the contents of the object by specifying the object'skey.Keys in Amazon S3 must be unique.If an object in the bucket already exists using thekeyvalue you're specifying for yourPutObjectcommand, then the old object will be replaced with your new object. Essentially, it's overwriting it.ShareFollowansweredOct 25, 2016 at 23:38Matt HouserMatt Houser35k66 gold badges7373 silver badges9292 bronze badgesAdd a comment|

The short answer is: you do not need to do this.The AWS SDK for JavaScript uses dynamic requires to load services. In other words, the classes are defined, butthe API data is only loaded when you instantiate a service object, so there is no CPU overhead in having the entire package around.The only possible cost would be from disk space usage (and download time), but note that Lambda already bundles theaws-sdkpackage on its end, so there is no download time, and you're actually using less disk space by using the SDK package available from Lambda than using something customized.ShareFollowansweredMay 17, 2016 at 0:40Loren SegalLoren Segal3,25211 gold badge2929 silver badges2929 bronze badgesAdd a comment|

S3 has no concept of directories.
S3 is an object store where each object is identified by a key.
The key might be a string like "logs/2014/06/04/system.log"Most graphical user interfaces on top of S3 (AWS CLI, AWS Console, Cloudberry, Transmit etc ...) interpret the "/" characters as a directory separator and present the file list "as is" it was in a directory structure.However, internally, there is no concept of directory, S3 has a flat namespace.
Seehttp://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMetadata.htmlfor more details.Knowing this, I am not surprised that empty directories are not synced as there is no directories on S3ShareFollowansweredDec 5, 2014 at 16:08Sébastien StormacqSébastien Stormacq14.5k55 gold badges4242 silver badges6464 bronze badgesAdd a comment|

We're using Amazon Web Services (AWS) and we have multiple web servers and a load balancer. The problem with the web servers is, that the $_SESSION is unique for each one. I'm keeping some information about the user in the $_SESSION.What is the proper way to synchronize this information? Is there any way to unite the place, where those sessions are being kept, or should I use MySQL to store this data (I don't really like the last option)?

Block Public Access feature is another layer of protection for buckets.
Amazon S3 buckets and objects are private and protected by default, with the option to use Access Control Lists (ACLs) and bucket policies to grant access to other AWS accounts or to public (anonymous) requests.Before the release of Block Public Access feature, was common to see more data leaks and breaches centered around data stored on S3 due to missconfiguration. It was not Amazon’s fault, was the company’s fault.So, if you want to make an bucket or objects within publicly accessible, first you need to disable this additional layer of security (disabling it does not means the bucket or objects are public, only means than you can make them public) and then make them public via ACL, bucket policies, etc.Reference:Amazon S3 Block Public Access – Another Layer of Protection for Your Accounts and BucketsShareFolloweditedDec 24, 2021 at 16:00answeredDec 24, 2021 at 14:28OARPOARP3,75911 gold badge1313 silver badges2323 bronze badges2well explained.

I am very confused with the S3 bucket policy settings.Here you can choose to block all public access.However, if you un-select these options, for the public to access the bucket and the objects, you still need to edit/add policies in the "Bucket policy" section:You need to edit the above policy to the following:{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::myapp/*"
},
{
"Sid": "2",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity 111111111"
},
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::myapp/*"
}
]
}If you do not specify"Effect": "Allow", "Principal": "*",, then the default policy is "block".So, why do we need the "Block public access" part if public is already blocked by default?

The Lambda execution runtime will provide your function invocation with a temporary session token (not a persistent/permanent access key / secret access key).Behind the scene, the Lambda Service will use the AWS Security Token Service (AWS STS) to assume the Lambda execution role of your Lambda function. This is why you must also add the Lambda Service principal as a trusted service principal in the trust policy of your execution role. And the result of this is a temporary session.The credentials for this temporary session are stored in a combination of the environment variablesAWS_SECRET_ACCESS_KEY,AWS_ACCESS_KEY_IDandAWS_SESSION_TOKEN.You should however not need to configure/specify any credentials manually, as the default credentials loader chain in the AWS SDK takes care of this automatically.ShareFollowansweredFeb 15, 2021 at 19:50httpdigesthttpdigest5,59122 gold badges1616 silver badges3131 bronze badges1Thanks for the perfect explanation, this fixed it.

I am deploying an AWS lambda function (with nodejs 12.x) that executes an AWS command ("iot:attachPrincipalPolicy") when invoked. I'm taking the credentials to run this command from the lambda execution environment variables.const AWS = require('aws-sdk/global');
const region = process.env['AWS_REGION'];
const accessKeyId = process.env['AWS_ACCESS_KEY_ID'];
const secretAccessKey = process.env['AWS_SECRET_ACCESS_KEY'];
AWS.config.region = region;
AWS.config.credentials = new AWS.Credentials(accessKeyId, secretAccessKey);
// attachPrincipalPolicy command from the AWS SDK hereWhen I test the function locally (withsam local start-api) it runs successfully, because in my AWS CLI I have set theACCESS_KEY_IDand secret of my administrator account.However when I deploy the function and invoke it the lambda fails on that command with a client error (the credentials are not valid), even when I give full admin access also to the lambda's execution role.Here I gave full permissions in an inline policy and I also explicitly added the pre-defined admin access policy too.I expected the AWS_ACCESS_KEY_ID that you get from the environment variables to grant me all the permissions that I have set in the lambda function's execution role but it looks like the privilege that I grant to the execution role are not reflected in these credentials.Is my assumption wrong? Where do these credentials come from and how can I find out what they allow me to do?

AWS Lambda credentials from the execution environment do not have the execution role's permissions

You could include several policies, one for each table, or provide a"*"for all DDB tables (note that"*"provides much broader permissions than is recommended, though).Policies:
# Give just CRUD permissions to one table
- DynamoDBCrudPolicy:

# Give just CRUD permissions to another table
- DynamoDBCrudPolicy:

I want to have multiple stacks based on a single CloudFormation template, but I'm getting naming conflicts. The simplest way to resolve this would seem to be prepending (or appending) theStackNameto each of the repeated resources, e.g. my lambda functions or roles.AWS talks aboutAWS::StackNamein the'Template Reference' section of the documentation, but there's no clear demonstration of how to do this.How can I prepend theStackNameto a CloudFormation resource?MyLambdaFunction

I want to temporarily restrict users from being able to access my static website hosted in s3 which sits behind a cloudfront distribution.Is this possible and if so what methods could i use to implement this?I've been able to restrict specific access to my s3 bucket by using a condition in the bucket policy which looks something like this:{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "VisualEditor0",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::my-bucket/*",
"Condition": {
"IpAddress": {
"aws:SourceIp": "12.34.56.73/32"
}
}
}
]
}which works and restricts my s3 bucket to my ip, however this means that the cloudfront url gets403 forbidden: access denied.When reading the AWS docs, it suggests that to restrict specific access to s3 resources, use anOrigin Access Identity. However they specify the following:If you don't see the Restrict Bucket Access option, your Amazon S3 origin might be configured as a website endpoint. In that configuration, S3 buckets must be set up with CloudFront as custom origins and you can't use an origin access identity with them.which suggests to me that i can't use it in this instance. Ideally i'd like to force my distribution or bucket policy to use a specific security group and control it that way so i can easily add/remove approved ip.

This is assuming there isn't a bug in your code somewhere and you're processing the same amount of work...AWS Lambda keeps instances of your application code running for some time to ensure subsequent requests to it are speedy, so it could simply be a matter of the garbage collection hasn't been run on that process running your code.Instead, what I would be more concerned about is paying for 512MB when your application isn't even using 256MB. Keep in mind that you don't pay for what you use, you pay for what you allocate.EDIT:
As percementblock's comment, keep in mind that changing memory allocation will affect your CPU and networking shares.ShareFolloweditedMar 22, 2019 at 13:54answeredMar 22, 2019 at 13:32MatthewMatthew25.2k99 gold badges8080 silver badges112112 bronze badges42Remember the memory setting also controls cpu and network.–cementblocksMar 22, 2019 at 13:47I'll give a more detailed look into the code, because another functions that I made don't have this trouble.

I have an AWS Lambda function built in .NET Core 2.1. Which is triggered by a SQS Queue.This function has a Max Memory of 512MB and a timeout of 2 min.Looking into the CloudWatch logs I'm seeing the Max Memory Used being increased after some number of executions. See the images below:It keeps increasing after some executions, it goes from 217MB to 218MB, after to 219MB and so on. This function is running multiple times and with a high frequence.Have anyone faced this on AWS Lambda? Thanks in advance for any help.

We are trying to write a lambda@edge function to trigger onviewer-request. I was able to find lots of examples on using JavaScript.e.g'use strict';
exports.handler = (event, context, callback) => {
console.log('Event: ', JSON.stringify(event, null, 2));
console.log('Context: ', JSON.stringify(context, null, 2));
const request = event.Records[0].cf.request;
// You can also store and read the redirect map
// in DynamoDB or S3, for example.
const redirects = {
'/r/music': '/card/bcbd2481',
'/r/tree': '/card/da8398f4',
};
if (redirects[request.uri]) {
return callback(null, {
status: '302',
statusDescription: 'Found',
headers: {
'location': [{
key: 'Location',
value: redirects[request.uri] }]
}
});
}
callback(null, request);
};The above code will redirect requests that matches a specific path. Can anyone advice on how to port a similiar code to python? or share resources/information on deploying python lambda@edge functions.Thanks

Terraform's-targetshould be for exceptional use cases only and you should really know what you're doing when you use it. If you genuinely need to regularly target different parts at a time then you should separate your applications into different directory so you can easily apply the whole directory at a time.This might mean you need to use data sources or rethink the structure of things a bit more but means you also limit the blast radius of any single Terraform action which is always useful.ShareFollowansweredFeb 14, 2018 at 9:52ydaetskcoRydaetskcoR54.9k88 gold badges162162 silver badges182182 bronze badgesAdd a comment|

Using a security group ID as a source only works when the traffic is addressed to the private IP.

The default AWS security group references itself in theSourcefield implying that the instance can communicate with itself:However, being logged in to the instance over SSH and trying to curl it by the DNS name resolving to the public instance's IP ends up with a curl timeout error.The only solution I've come up with is to add the public IP of the instance into the security group instead of the sec group ID, but it's not flexible - I don't want any so highly focused security groups.Why doesn't the default security group, assigned to an instance, allow all traffic from the instance itself?

Redshiftis a data warehouse and generally used for OLAP(analytical) processes. Analytical DBs are too slow for transactional processes and do not generally obey primary key foreign key constraints. WhileAuroraandDynamoDBare OLTP(transactional) database. In your case if you are to keep all the data in a single JSON entry it would be better to use DynamoDB but I would suggest to use Aurora as it is a RDBMS having fix schema, but you will have to keep multiple entries per user in another table although retrieving them will be just a single join query.ShareFollowansweredDec 21, 2017 at 5:53Sar009Sar0092,22655 gold badges3030 silver badges5050 bronze badgesAdd a comment|

I've been reading a whole bunch on these databases but still am just not sure what to use.I need a backend for a game I am developing. This backend needs to store user accounts, the items the user has and the score of the user.At the start of the game the user will query the database for their items. When they get a new item it will add it to their account on the database. Items will be stored as a large JSON blob.So this database will not be accessed frequently. It does not need to store a huge amount of data, as it really only needs 1 entry per user. But it should be able to scale into the millions.I will need to query the database to determine what users belong to which particular categories, or teams.As cheap as I can get on storing this data in a reliable and adequately fast way is ideal.What is the best option for this?

I'm using an npm package callednode-s3-clientwhich is a high-level wrapper for theaws-sdkfor Node.js, to upload a local project directory to an S3 bucket.Using that package, I'm passing some metadata to my files, namely key value pairs forExpiresandCache-Control.

However when I check my S3 bucket, the headers that I'm settingonly appliesto JS and CSS files, these headers are not applied to images.I've gone through the documentation of the package and aws-sdk but I can't seem to find what causes the issue of selectively applying my metadata to some files and not applying to others.Here's my config object:const s3 = require('node-s3-client')

I figured it out. The request timeout was not long enough for the upload to finish, thus it was making the call again and so on and so on. To resolve the issue, I set the timeout for the request to 0, giving the request all the time it needs to finish the upload. With this in place, it properly returns a 201 response back to the client.exports.create = function(req, res) {
req.setTimeout(0); // <= set a create request to no timeout length.
var stream = fs.createReadStream(req.file.path);
var params = {
Bucket: 'aws bucket',
Key: req.file.filename,
Body: stream,
ContentLength: req.file.size,
ContentType: 'audio/mp3'
};
var s3upload = s3.upload(params, options).promise();
// return the `Promise`
s3upload
.then(function(data) {
console.log(data);
return res.sendStatus(201);
})
.catch(function(err) {
return handleError(err);

I'm hosting my static website on AWS S3, with Cloudfront as a CDN, and I'm wondering how I can get clean URLs working.I currently have to go toexample.com/about.htmlto get the about page. I'd preferexample.com/aboutas well as across all my other pages. Also, I kind of have to do this because my canonical URLs have been set with meta tags and search engines, and it's gonna be a bit much to go changing them.Is there a setting in Cloudfront that I'm non seeing?UpdatesThere are two options I've explored, one detailed by Matt below.First is trimming.htmloff the file before uploading to S3 and then editing the Content Header in the http for that file. This might work beautifully, but I can't figure out how to edit content headers from the command line, where I'm writing my "push website update" bash script.Second is detailled by Matt below and leverages S3's feature that recognizes root default files, usually index.html. Might be a great approach, but it makes my local testing challenging, and it leaves a trailing slash on the URLs which doesn't work for me.

You can get some of the info you are looking for by using theattribute_definitionsattribute of aTableobject, like this:import boto3
ddb = boto3.resource('dynamodb')
table = ddb.Table('MyTable')
attrs = table.attribute_definitionsThe variableattrswould now contain a dictionary of all of the attributes you explicitly defined when creating the table which normally is only the attributes that are used as keys in some index.However, since DynamoDB is schema less you can store any combination of other attributes in an item in DynamoDB. So, as the comment above states, the only way to know all attributes used in all items is to iterate through all of the items and build a set of attributes found in each item.ShareFollowansweredNov 16, 2016 at 14:40garnaatgarnaat45k77 gold badges125125 silver badges103103 bronze badgesAdd a comment|

BestAt this moment I'm using Boto3 in python 2.7 and what I would like to have is:
The column headers of my specific DynamoDB table.At this moment,I'm dealing with a very large dynamoDB table, with 80 columns and + 1.00O.000 records. And the task which I've is, to manipulate these data. To do this, I'm making use of chunks. This means that I'm retrieving each time 1000 rows, from my data-table and manipulate them and write the new result to a csv. (This is required, by some reasons).But because I'm using chunks, it can be that not every chunk contains 80 columns, this means that it sometimes can contain 79 or 78 columns. This happens when there are no values available for a specific column in a chunk.And this isn't desirable because at the end of the day, all those csv's should been concatenated again to each other, and therefore, each csv should contain the equal amount of columns.Thus my idea, which I've is : Add empty columns to the chunk-csv's who doesn't contain all the required columns.But therefore, I've to know, what the headers, attributes, field names are from my table (or the structure) + The thing is, those column headers are dynamic, there can't be a static list of headers And it can be, that suddenly new records are added with a unique column, (which means that the next time, I would receive 81 columns for each of my csv's) - Thus those header knowledge should come from my table / amazon awsKind regards

Modifying Frédéric's answer:aws ec2 describe-instances --output text --query \
'Reservations[].Instances[].[PublicDnsName, Tags[?Key==`budget_cluster`].Value | [0]]'Would produce:ec2-xxxxx.amazonaws.com zzzzz
ec2-bbbbb.amazonaws.com yyyyyI've changed the output to text, which removes as much formatting as possible and selected the individual tag value with| [0]since there will only ever be one per instance anyway. Finally, I removed the[]at the end so that the resulting list isn't flattened. That way in text output each entry will be on its own line.You can also make this more robust by only selecting instances that actually have that tag. You could do so with further modifications to the--queryparameter, but it is better in this case to use the--filtersparameter since it does service-side filtering. Specifically you want thetag-keyfilter:--filters "Name=tag-key,Values=budget_cluster"aws ec2 describe-instances --output text \
--filters "Name=tag-key,Values=budget_cluster" --query \
'Reservations[].Instances[?Tags[?Key==`budget_cluster`]].[PublicDnsName, Tags[?Key==`budget_cluster`].Value | [0]]'Would still produce:ec2-xxxxx.amazonaws.com zzzzz

You can also specify headers, URL paths and query stringsto be used as the cache key.It's not clear what you have done at this point but you should be able to do one of the following to achieve your goals:Enable caching at the stage level, and disable at the method level for the POST method.Disable caching at the stage level, and enable caching at the method level for the GET method.ShareFollowansweredMay 20, 2016 at 15:41Mark BMark B191k2525 gold badges310310 silver badges307307 bronze badgesAdd a comment|

Use the Java S3 SDK. If you upload a file calledx.dbto an S3 bucketmybucket, it would look something like this:import com.amazonaws.services.s3.*;
import com.amazonaws.services.s3.model.*;
...
AmazonS3 client = new AmazonS3Client();
S3Object xFile = client.getObject("mybucket", "x.db");
InputStream contents = xFile.getObjectContent();In addition, you should ensure the role you've assigned to your lambda function has access to the S3 bucket. Apply a policy like this:"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": [

Yes, it's possible.You use theRunInstancesAPI method.Launches the specified number of instances using an AMI for which you have permissions.To completely get rid of an instance, useTerminateInstance.Shuts down one or more instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds.The language is a bit confusing because it says "Shuts down one or more instances", but in fact it totally removes them.ShareFolloweditedFeb 10, 2016 at 1:27answeredFeb 10, 2016 at 1:25Eric J.Eric J.149k6363 gold badges343343 silver badges556556 bronze badges3Thanks, how is this different thanRequestSpotInstances?–Jake WilsonFeb 10, 2016 at 1:26RequestSpotInstance allows you to place a bid for an available instance at the current spot market price.

I need to programmatically create a new instance, pick the instance type, pick the AMI, start it up and run some deployment scripts to get things rolling.I would think there is a way to do this with the AWS SDK but I'm just not seeing it.On a related note, also need to be able to programmatically destroy a shutdown instance.

There are lots of factors, that maximize the CPU utilization on PostgreSQL like:Free disk spaceCPU UsageI/O usage etc.I came across with the same issue few days ago. For me the reason was that some transactions was getting stuck and running since long time. Hence forth CPU utilization got inceased. I came to know about this, by running some postgreSql monitoring command:SELECT max(now() - xact_start) FROM pg_stat_activity
WHERE state IN ('idle in transaction', 'active');This command shows the time from which a transaction is running. This time should not be greater than one hour. So killing the transaction which was running from long time or that was stuck at any point, worked for me. I followedthispost for monitoring and solving my issue.Postincludes lots of useful commands to monitor this situation.ShareFolloweditedJun 23, 2018 at 8:19Keshav4,42888 gold badges3131 silver badges5050 bronze badgesansweredOct 11, 2016 at 19:33Rohini ChoudharyRohini Choudhary2,44322 gold badges2222 silver badges3131 bronze badgesAdd a comment|

Attempted to migrate my production environment from Native Postgres environment (hosted on AWS EC2) to RDS Postgres (9.4.4) but it failed miserably. The CPU utilisation of RDS Postgres instances shooted up drastically when compared to that of Native Postgres instances.My environment details goes hereMaster: db.m3.2xlarge instanceSlave1: db.m3.2xlarge instanceSlave2: db.m3.2xlarge instanceSlave3: db.m3.xlarge instanceSlave4: db.m3.xlarge instance[Note: All the slaves were at Level 1 replication]I had configured Master to receive only write request and this instance was all fine. The write count was 50 to 80 per second and they CPU utilisation was around 20 to 30%But apart from this instance, all my slaves performed very bad. The Slaves were configured only to receive Read requests and I assume all writes that were happening was due to replication.Provisioned IOPS on these boxes were 1000
And on an average there were 5 to 7 Read request hitting each slave and the CPU utilisation was 60%.
Where as in Native Postgres, we stay well with in 30% for this traffic.Couldn't figure whats going wrong on RDS setup and AWS support is not able to provide good leads.Did anyone face similar things with RDS Postgres?

To allow everyone to get objects, but not allow anyone to list objects, you can apply a bucket policy:{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AddPerm",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": [
"arn:aws:s3:::mybucket/myfolder1/*",
"arn:aws:s3:::mybucket/myfolder2/*"
]
}
]
}Note that anyone who discovers the URL of an object can retrieve that object.ShareFollowansweredOct 8, 2015 at 21:20jarmodjarmod75k1616 gold badges124124 silver badges128128 bronze badges4So its not possible to have something like "arn:aws:s3:::mybucket/**/*.txt" to say all the text files?

I have a sub directory under a bucket with ~7000 sub directories. And then each of those sub directories may have 1-100 files.I need the files to be public, but I don't want anyone to be able to see the list of subdirectories, or even the list of files under a given directory.I know I can set the ACL for the files to read-only, and then i think I can set the directory to private. But for this many files, I'm hoping there is a much easier solution?

+50You cannot use the--cache-controloption that aws cli provides to invalidate files in CloudFront. The--cache-controloption maps directly to theCache-Control headerand CloudFront caches the headers along with the file, so if you change a header you must also invalidate to tell CloudFront to pull in the changed headers.If you want to use the aws cli, then you must parse the output of the sync command and then use the aws cloudfront cli.Or, you can uses3cmdfrom s3tools.org. This program provides the the--cf-invalidateoption to invalidate the uploaded filed in CloudFront and a sync command synchronize a directory tree to S3.s3cmd sync --cf-invalidate <local path> s3://<bucket name>Read, thes3cmd usage pagefor more details.ShareFollowansweredApr 14, 2015 at 19:34Keith ShawKeith Shaw64466 silver badges77 bronze badges2The --cf-invalidate option gives the following error for me: ERROR: Parameter problem: Unable to translate S3 URI to CloudFront distribution name: s3://<bucket name>–Lars HøidahlSep 23, 2021 at 6:33I had that error (Unable to translate S3 URI to CloudFront distribution name) when my S3 origin domain name in the CloudFront distribution was set tobucket_regional_domain_name(xxxx.s3.eu-west-2.amazonaws.com) instead ofbucket_domain_name(xxxx.s3.amazonaws.com).

I have a rails app that uses aws cli to sync bunch of content and config with my s3 bucket like so:aws s3 sync --acl 'public-read' #{some_path} s3://#{bucket_path}Now I am looking for some easy way to mark everything that was just updated in sync to be marked as invalidated or expired for CloudFront.I am wondering if there is some way to use-cache-controlflag thataws cliprovides to make this happen. So that instead of invalidating CouldFont, just mark the files as expired, so CloudFront will be forced to fetch fresh data from bucket.I am aware ofCloudFront POST APIto mark files for invalidation, but that will mean I will have detect what changed in the last sync, then make the API call. I might have any where from 1000s to 1 file syncing. Not a pleasent prospect. But if I have to go this route, how would I go about detecting changes without parsing the s3 sync's console output of-course.Or any other ideas?Thanks!

So I believe I resolved this issue. It appears as if aws was dynamically changing ip addresses. When I was referencing ftp.domain.com for my passiveip the ip that it resolved to didn't match the initial ip tied to the cname record.The solution was to assign a static elastic ip to my ec2 instance and set my passiveip in pureftp to my static elastic ip. Thus far it appears to have resolved my issue.ShareFollowansweredFeb 6, 2015 at 7:21Code JunkieCode Junkie7,6922727 gold badges8080 silver badges143143 bronze badges2Seems legit.

It was returning an alternate IP address. Even after I gave the machine a static ip address it still failed if I set ForcePassiveIP to use ftp.domain.com. I ended up just hard setting the ForcePassiveIP with the static ip.–Code JunkieFeb 6, 2015 at 15:00Add a comment|

Object metadata is covered by the GetObject action. For versioned objects you would instead use GetObjectVersion. So the policies you have listed should be working for accessing metadata. There's a great summary of all the permissions and what each one coversherein the AWS docs.If you're able to recreate the error using the AWS REST interface instead of the web console you can get more detailed error information. Using a tool likethis perl command line utilitycan be useful in that regard. Using this you can determine the specificS3 error codesthat you don't typically see when using their web console. Knowing the specific error that's causing the problem will go a long way to determining why the users can't edit the metadata despite your having the correct policies in place.ShareFollowansweredJul 21, 2014 at 14:51Bruce PBruce P20.3k88 gold badges6464 silver badges7373 bronze badges1Ok, I've gotten the utility you linked to working.

I'm new to AWS and RDS. I've combed through help files and other stackflow questions, but can't seem to find out if i'm doing something wrong.
When I go to my RDS Instance, I seeSecurity Groups:default( active )I click default, and it takes me to the SG page, where I create new groups.
However, any rules I put in those new groups don't work, only the rules I put in the default group works. In some of the documentation, I see the screenshots and the beside the Security Groups on the instance page, it doesn't list default, but a user created group.So is there some way to make all the new groups active or a way to change which group has precedence on that Instance page? Or am I going to have to put all my rules in the default group?

I just began to use S3 recently. I accidentally made a key that contains a bad character, and now I can't list the contents of that folder, nor delete that bad key. (I've since added checks to make sure I don't do this again).I was using an old "S3" python module from 2008 originally. Now I've switched to boto-2.0, and I still cannot delete it. I did quite a bit of research online, and it seems the problem is I have an invalid XML character, so it seems a problem at the lowest level, and no API has helped so far.I finally contacted Amazon, and they said to use "s3-curl.pl" fromhttp://aws.amazon.com/code/128. I downloaded it, and here's my key:<Key>info/[01</Key>I think I was doing a quick bash for loop over some files at the time, and I have "lscolors" set up, and so this happened.I tried./s3curl.pl --id <myID> --key <myKEY> -- -X DELETE https://mybucket.s3.amazonaws.com/info/[01(and also tried putting the URL in single/double quotes, and also tried to escape the '[').Without quotes on the URL, it hangs. With quotes, I get "curl: (3) [globbing] error: bad range specification after pos 50". I edited the s3-curl.pl to docurl --globoffand still get this error.I would appreciate any help.

Using below command you can able to see the values from stage file:select t.$1, t.$2 from @mystage1 (file_format => myformat) t;Based on the data you can change your copy command as below:COPY INTO my_table(col1, col2, col3) from (select $1, $2, try_to_date($3) from @mystage1)

Assuming this is a single page app (SPA) since this is react - in other words, there is no file in your s3 bucketexample-1/index.html?For single-page apps, whatever is delivering the static contents needs to return the rootindex.htmlfile for all unmatched paths. In CloudFront, you can click on the distribution, then click on "Error pages", click "Create a custom error response", select 404 for the HTTP error code, select "create a custom error response" and put/index.htmlin the response page path with a 200 for the response code.

To get output from an ECS/Fargate task, I think you have to use theTask Token Integrationinstead of Run Job (Sync) which is usually recommended for Fargate tasks. You can pass the token as a container override ("TASK_TOKEN": "$$.Task.Token"). Then inside your image you need some logic like this:client = boto3.client('stepfunctions')
client.send_task_success(
taskToken=os.environ["TASK_TOKEN"],
output=output
)to pass it back.ShareFollowansweredFeb 10, 2022 at 20:50Drew BollingerDrew Bollinger18622 silver badges77 bronze badgesAdd a comment|

Have previously worked with lambda orchestration using AWS step function. This has been working very well. Setting the result_path of each lambda will pass along arguments to subsequent lambda.However, I now need to run a fargate task and then pass along arguments from that fargate task to subsequent lambdas. I have created a python script that acts as the entrypoint in the container definition. Obviously in a lambda function thehandler(event, context)acts as the entrypoint and by defining areturn {"return_object": "hello_world"}its easy to pass a long a argument to the next state of the state machine.In my case though, I have task definition with a container definition created from this Dockerfile:FROM python:3.7-slim
COPY my_script.py /my_script.py
RUN ln -s /python/my_script.py /usr/bin/my_script && \
chmod +x /python/my_script.py
ENTRYPOINT ["my_script"]Hence, I am able to invoke the state machine and it will execute my_script as intended. But how do I get the output from this python script and pass it along to another state in the state machine?I have found some documentation on how to pass along inputs, but no example of passing along outputs.

This is likely down toburst capacityin which you gain your capacity over a 300 second period to use for burstable actions (such as scanning an entire table).This would mean if you used all of these credits other interactions would suffer as they not have enough capacity available to them.You can see the amount of consumed WCU/RCU via either CloudWatch metrics or within the DynamoDB interface itself (via the Metrics tab).ShareFollowansweredAug 19, 2020 at 7:24Chris WilliamsChris Williams33.5k44 gold badges3434 silver badges7171 bronze badges0Add a comment|

Since your error that you received says "Unknown host" it gives you a clue where you can troubleshoot first.Refer tothe official psycopg2 documentationfor the guidance on how to use the arguments. You can connect using the dsn parameter or you can use keyword arguments. Since you are using keyword arguments (the second option in the documentation), you should specify the host without the port and the database and see if that works. That means thatdsn_hostname = "redshift-cluster-1.xxx.xxx.redshift.amazonaws.com".This is very similar tothis Stack Overflow question and answer here, if you would like more information.Also I really hope those aren't your actual credentials, if so please remove them for the security of your database!ShareFollowansweredAug 11, 2020 at 21:19kayelowkayelow31122 silver badges33 bronze badges1@RohanNaik Hope that helped, if so you can mark your question as answered.–kayelowAug 12, 2020 at 22:15Add a comment|

Amazon maps-out typical latency between IP addresses and AWS regions. ChooseLatency-based Routingto have the fastest response.Geolocationmaps the IP addresses to geographic locations. This permits rules like "send all users from Côte d'Ivoire to the website in France", so they see a language-specific version. It can redirect bycountry, region (eg Oceania) and US state. Geolocation cares more about the location of users rather than the speed of their connection.Geolocation pre-dates GDPR.

AWS implements latency routing policy based on the ip address of resolver or masked ip address of client. It will help to find the region of low latency.If both geolocation policy and latency policy are based on the IP address of client, it comes to several questions:what's the difference between them?What's the purpose of Geolocation routing policy?Is geolocation policy used for complying the law of different country? e.g. GDPR, cookie usage.Europe: GDPRChina: data must be stored in China.In which case should I use Geolocation routing policy rather than latency policy?Referencehow does AWS Route 53 achieve latency based routing:https://youtu.be/PVBC1gb78r8?t=1963https://youtu.be/PcoQY82SDHw?t=622How does AWS Route 53 achieve latency based routing?

There are two AWS services that might assist:TheAmazon Elastic Transcoder servicelets you convert media files stored in Amazon S3. For example, you can convert large, high-quality digital media files into formats that users can play back on mobile devices, tablets, web browsers, and connected televisions.TheAWS Elemental MediaConvertis a file-based video processing service that provides scalable video processing for content owners and distributors with media libraries of any size.These will not convert "while uploading". Rather, they willtranscode videosalready stored in Amazon S3 and will save the results back to S3. To reduce the storage size of a video, you would need to change some attributes (eg dimensions, quality, encoding method) that would result in a smaller file.ShareFollowansweredNov 25, 2019 at 21:11John RotensteinJohn Rotenstein254k2626 gold badges408408 silver badges497497 bronze badgesAdd a comment|

the subscriber end.Does it apply to SQS consumers, specially a FIFO SQS? I have a use case where one of the consumers needs to maintain the order in which the messages were sent. If this is not the case, I would need to use something else.

Since that in external tables it is possible to onlyselectdata this one is enough to checkusagepermission over the external tables:SELECT schemaname, tablename, usename,
has_schema_privilege(usrs.usename, schemaname, 'usage') AS usage
FROM SVV_EXTERNAL_TABLES, pg_user AS usrs
WHERE schemaname = '<my-schema-name>'

In the Lambda execution environment, the root logger is already preconfigured. You'll have to work with it or work around it. You could do some of the following:You can set the formatting directly on the root logger:root = logging.getLogger()
root.setLevel(logging.INFO)
root.handlers[0].setFormatter(logging.Formatter(fmt='[%(asctime)s.%(msecs).03d] [%(name)s,%(funcName)s:%(lineno)s] [%(levelname)s] %(message)s', datefmt='%d/%b/%Y %H:%M:%S'))You could add the Watchtower handler to it (disclaimer: I have not tried this approach):root = logging.getLogger()
root.addHandler(cw_handler)However I'm wondering if you even need to use Watchtower. In Lambda, every line you print tostdout(so even just usingprint) get logged to Cloudwatch. So using the standardlogginginterface might be sufficient.ShareFollowansweredFeb 24, 2019 at 20:20Milan CermakMilan Cermak7,75433 gold badges4545 silver badges6060 bronze badges1How would you simultaneously support local logging (as per OP's attempt) and CloudWatch logging as per your excellent answer?–jtlz2Dec 15, 2022 at 10:25Add a comment|

I have written following code to enable Cloudwatch support.import logging
from boto3.session import Session
from watchtower import CloudWatchLogHandler
logging.basicConfig(level=logging.INFO,format='[%(asctime)s.%(msecs).03d] [%(name)s,%(funcName)s:%(lineno)s] [%(levelname)s] %(message)s',datefmt='%d/%b/%Y %H:%M:%S')
log = logging.getLogger('Test')
boto3_session = Session(aws_access_key_id=AWS_ACCESS_KEY_ID,
aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
region_name=REGION_NAME)
cw_handler = CloudWatchLogHandler(log_group=CLOUDWATCH_LOG_GROUP_NAME,stream_name=CLOUDWATCH_LOG_STREAM_NAME,boto3_session=boto3_session)
log.addHandler(cw_handler)Whenever i try to print any logger statement, i am getting different output on my local system and cloudwatch.Example:log.info("Hello world")Output of above logger statement on my local system (terminal) :[24/Feb/2019 15:25:06.969] [Test,<module>:1] [INFO] Hello worldOutput of above logger statement on cloudwatch (log stream) :Hello worldIs there something i am missing ?

In addition to RDS for PostgreSQL, which has a 32 TiB limit, you should take a look at Amazon Aurora PostgreSQL, which has a 64 TiB limit. In both cases, the largest single table you can create is 32 TiB, though you can't quite reach that size in RDS for PostgreSQL as some of the space will be taken up by the system catalog.Full disclosure: I am the product manager for Aurora PostgreSQL at AWS.ShareFollowansweredFeb 12, 2019 at 14:46Kevin JKevin J9111 bronze badge1Then why does this say 32 TiB?docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/…–KongressAug 5, 2020 at 15:20Add a comment|

For conditional logic in an SES template you can use if else statements like you would in code. For your example you would use something like<p>{{sender}} has invited you to join team {{#if teamName}}{{teamName}}{{/if}}</p>Taken from the following documentationhttps://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-personalized-email-advanced.htmlShareFollowansweredFeb 1, 2019 at 8:07bencrinklebencrinkle28844 silver badges1414 bronze badges0Add a comment|

The resulting role that SAM creates for you is just the name of your function with "Role" added to the end. You can use this information to get the Role or properties of it using normal CloudFormation functions.For example, if you wanted to access the role ARN ofMyFunction, you would use!GetAtt MyFunctionRole.Arnin your SAM YAML template. The same principle should apply for!Refand other functions.ShareFollowansweredSep 19, 2018 at 23:20Keeton HodgsonKeeton Hodgson47733 silver badges88 bronze badgesAdd a comment|

Naming is always tough.For general naming - this is a good answer:https://softwareengineering.stackexchange.com/a/130104In addition, the scope of the namespace of your lambda functions is a consideration - e.g. ifallof your functions relate to users in application XYZ for enterprise ABC, thencreateis sufficient.However, if you have lambda functions for both enterprises ABC & DEF, and each have multiple applications with user management andmayneed differentcreatemethods for different things, then you may need something likeAbcApplicationxyzCreateUser.One other comment - in English,commandObject(e.g.createUser)readsbetter and sounds more natural when said aloud compared toobjectCommand(e.g.userCreate). But I have found it easier to have the contextual parts (e.g.companyorapplication; if needed, but better avoided if possible) at the start as it facilitates tools to organize methods better (contextCommandObjecte.g.AbcCoCustomerServiceAppCreateUser).In short, make it simple, avoid using anything that is implicitly obvious, but allow for distinguishing between different applications/systems/entities in the namespace if needed.ShareFollowansweredAug 9, 2018 at 14:12Brian QuinnBrian Quinn14622 bronze badges1This is some of the most sensible advice I've read about naming is as long as I can remember!–mbigrasMar 13, 2021 at 7:52Add a comment|

I'm building an API with the Serverless framework. Endpoints are defined on Amazon API Gateway, where each signature is mapped to an individual Lambda.What is a good naming convention for the Lambdas here? For example, the candidates forPOST /usercould be:userPostcreateUser

Using the task definition (portal or JSON) you can define"secrets"inside the"containerDefinitions"section which will be retrieved from secrets manager.Note: At the time of writing, Fargate only supports secrets that are a single value, not the JSON or key value secrets. So choose OTHER when creating the secret and just put a single text value there.{
"ipcMode": null,
"executionRoleArn": "arn:aws:iam::##:role/roleName",
"containerDefinitions": [
{

"secrets": [{

}],

],
"requiresCompatibilities": [

"networkMode": "awsvpc",

}Note: that execution role defined in the task needs a policy attached such asSecretsManagerReadWriteMore info in docsShareFollowansweredMay 13, 2020 at 1:06lkolko8,27199 gold badges4545 silver badges6262 bronze badgesAdd a comment|

As part of some testing that I was doing, I replied STOP to an SMS message that was sent via Amazon's Pinpoint service. I received the acknowledgement that I had been removed from further notifications.I want to opt back in to receiving those messages, but I can't figure out how to do that. I looked at the Pinpoint documentation and I did not see a way to do it. I looked in the Amazon Pinpoint Console and I did not see a way to remove a number from the blacklist. I have tried the standard terms that other SMS providers use such as UNSTOP, UNBLOCK, and START, but none of those work either. Does anyone have any suggestions. I do not want to contact Amazon support about this unless I have to.

Running on a different hosting will cause extra latency.Let's do the math on AWS RDS for the smallest instances (taking eu-west-1 region as example)Running on RDS: db.t2.micro $0.018 per hour, or $12.96 per month for RDS. Free the first year underAWS free tier.Running on EC2: t2.micro (You configure MySQL and backups, ...), $0.0126 per hour, or $9.07 per month.

I have wordpress application running on my EC2 - AWS. I haven't decide which one is Amazon RDS or my own database on different hosting. Which one is the cheapest to use? Let's say I have my own MySQL database from Lunarpages or Bluehost hosting, to allow my wordpress on EC2 instance to connect/remote to my database on Lunarpages not allow my wordpress to connect remote to Amazon RDS. Which one is the cheapest to use? I heard people saying when you use Amazon RDS is very expensive, so I thought maybe to save costs to allow my wordpress to connect to my own database not Amazon RDS for wordpress. I don't know it is true or not. I don't know how it performance well. Which one is the best one. Any suggestion appreciated. Thank you.
