The AWS SQS Queue url is provided in the following format (seethis link):https://{REGION_ENDPOINT}/queue.|api-domain|/{YOUR_ACCOUNT_NUMBER}/{YOUR_QUEUE_NAME}If you had given us the code you used to retrieve the urls in java, we could have seen what the real root cause is. What you have got as the response for your JAVA SDK call is anAWS Endpoint. (seethis link).To reduce data latency in your applications, most Amazon Web Services
offer a regional endpoint to make your requests. An endpoint is a URL
that is the entry point for a web service. For example,https://dynamodb.us-west-2.amazonaws.comis an entry point for the
Amazon DynamoDB service.You can try out to retrieve the SQS URL using the JAVA SDK using the following code. This is for a single Queue URL given the Queue name. (Seethis doc)AmazonSQS sqs = AmazonSQSClientBuilder.defaultClient();
String queue_url = sqs.getQueueUrl(QUEUE_NAME).getQueueUrl();You can also use thelistQueuesmethod to retrieve the Queue URL list, as given inthis doc.If you are still getting the SQS Endpoint...If you keep on getting the SQS Queue URL Endpoint, instead of the SQS actual Queue URL, you can use the endpoint to access and manipulate the queue as you require. Have a look atthis example written in Java, which will help you understand how to use the endpoint and create a workaround with it. | When using AWS CLI versionaws-cli/1.15.50,Python/3.7.0,Darwin/16.7.0,botocore/1.10.49, the commandaws sqs list-queuesreturns a list of the formathttps://us-west-2.queue.amazonaws.com/<a number>/<queue-name>When I call the equivalent from the Java SDK (SDK version 1.11.344
called from Scala version 2.12.6), I get a list of the formathttps://sqs.us-west-2.amazonaws.com/<a number>/<queue-name>PLEASE NOTE: the numberis the samein both URLs as are the corresponding queue names.The differences are:The CLI begins with the region (us-west-2) while the SDK begins withsqs.After the region, the CLI's domain name is.queue.amazonaws.combut the JDK has just.amazonaws.com. (The SDK does not have the tokenqueue..)I get the same results when usingget-queue-urlandgetQueueUrl(either overload in the SDK).Messages sent usingaws sqs send-messagewith the URL returned by the CLI are not received by the Scala program using the URL returned by the AWS Java SDK.What am I doing wrong? | SQS Queue URLs different from AWS CLI than from Java SDK |

I know you don't want to use a DB but dynamodb can work well for this kind of thing. If you have something you can use as a good partition key then it will still be quite performant. It will still add a very small amount of time to your lambda run time and, of course, you will be charged for your dynamodb capacity & data. I use this successfully to discard duplicate messages.The other thing that might be worth looking into would be elasticache which has memcached and redis versions. This would be faster - if performance is a particular focus - but is not persistent like DynamoDB. | Since several of the triggers for AWS Lambda can only guarantee message delivery "at least once" (SQS and IoT with QoS=1), I wonder what's the best way to identify a duplicate message and ignore it.I can see that I currently get several duplicate messages, triggering my lambdas twice, causing noise and invalid data as a consequence.In my client, I solve it by just storing a list of message IDs that I've processed, but in the Lambdas, I have nowhere to store a state.Of course I could maintain a DB table of processed message IDs but it seems like overkill to me (and probably adds extra billed runtime to the lambdas). A simple key/value store service in memory would be enough.What other solutions are you guys using? | AWS Lambda - how to identify duplicate messages |
In the Listener configuration, you are forwarding the default HTTP port80to port30987on the back-end server. So this tells me that the back-end server is listening for HTTP requests on port30987.You then added an SSL listener on the default port443but you are forwarding that to port443on the back-end server. Do you have something on your back-end listening on port443in addition to30987?The most likely fix for this is to change the SSL listener on the load balancer to forward to port30987on the back-end by setting that as the "Instance Port" setting. | I have a AWSLoadBalancerwhich created usingKube,KopsandAWS.

I don't have a full terraform-only solution to this.The approach I have is to run a small script to get the current desired capacity, set a variable, and then use that variable in the asg.handle-desired-capacity:

As of November 2019 it is possible to convert existing DynamoDB tables to Global Tables without data loss."Starting today, you can convert your existing DynamoDB tables to
global tables with a few clicks in the AWS Management Console, or
using the AWS Command Line Interface (CLI), or the Amazon DynamoDB
API. Previously, only empty tables could be converted to global
tables. You had to guess your regional usage of a table at the time
you created it. Now you can go global, or you can extend existing

If I understand the question correctly, your question is about SQS Queue endpoint not having theus-east-1appended at the beginning of the endpoint. It is not a legacy endpoint.

endpoints do not include a region. Some services, such as Amazon EC2,

To query your table usingCreatedDatewithout knowing theItemId, you can use Global Secondary Index write sharding by adding an attribute (e.g.,ShardId) containing a (0-N) value to every item that you will use for the global secondary index partition key.Depending on how your items are distributed againstCreatedDate, you can set theShardIdso that it is likely to have evenly distributed access patterns. For example:YYYY,YYYYMMorYYYYMMDD. Then, you create a global secondary index withShardIdas an index partition key andCreatedDateas an index sort key.Knowing the primary key for your GSI (since theShardIdvalue is derived fromCreatedDate), you can query the table for the 100 most recent items with query'sLimitparameter (orLastEvaluatedKeyif your items set size is larger than 1 MB of data).SeeUsing Global Secondary Index Write Sharding for Selective Table Queries. | I have created a dynamo db table with name- "sample".It has below columns.

A load test could be as simple as pinging the healh-check URL of your Beanstalk application.Write a threaded/concurrent program in the language of your choice to bombard your Beanstalk application with HTTP requests to elicit HTTP 200 responses.At a sufficiently high request rate (which you could facilitate by increasing the degree of concurrency), you could observe auto-scaling kick in to launch newer instances of my environment.For every request from the concurrent program, you should check the response is a 200 OK, if not log that as an anomaly.Measure the mean time between request and response to give you an indication of whether your responses are lagging.You could repeat the above process with the operations that you expect to be most popular for your application.One such plausible operation is that ofusers logging in, for which you would need to have setup a large number of dummy users in the (development) database. Now, instead of requesting the health-check URL, you would perform POST requests with the authentication credentials per-user to the/loginURL of your app. | I have my laravel application (which is serving Rest API's) configured in elastic beanstalk environment. currently i have configured 1 t2.medium Ec2 instance under application load balancer. how to load test to check the maximum number of concurrent users the environment can handle? | Load test concurrent users in elastic beanstalk environment |
Yes. You can define catch handlers in your Step Function to handle failing lambdas and rerun them, or do whatever you need on failures.Here's an example of triggering Step Functions from file uploads to S3:https://aws.amazon.com/blogs/compute/synchronizing-amazon-s3-buckets-using-aws-step-functions/That said, if all you need is a simple re-try logic, you might be able to get there faster using SQS. When SQS clients receive messages from the queue, they are not actually removed immediately, but rather SQS puts a hold on the messages. If a client doesn't delete the messages within a certain time, then those messages are put back into the queue.Unfortunately, there's currently no way to trigger lambdas directly from SQS, but you can set up one or more CloudWatch events to poll SQS at regular intervals. | Context:I have a pipeline of 6 lambda functions (chained together), triggered by an SNS notification which is generated whenever a file lands on S3. This pipeline essentially takes the file(few GBs), filters it (Spark cluster is created to run the job, then deleted at the end), and inserts it into a DB. Lambdas are orchestrating the flow.Issues:If one Lambda fails, the chain breaks hence no effective failure handling. Secondly, we experience timeouts if a polling/computation takes longer than 5 minutes, so no effective retry. It takes a long time to test/debug an issue if a lambda fails. Also there is no visibility, say for example how many jobs failed and how many passed? we dont know. Getting a bunch of SNS notifications on email is not very effective/helpful. If the chain breaks, we cannot perform cleanup operations like deleting SPark cluster or housekeeping steps.My Questions:Is AWS Step Functions a good choice for solving the above issues? When would you not use a Step Function service? If you cannot invoke Step Function through SNS, then what would be the best way to call it whenever a file lands on S3? Feel free to share any other approach to easily and effectively tackle this usecase. | Challenges of using AWS Lambda chain |
The temporary copy of the object is accessible by fetching the object as usual, using the same object key. There isn't a separate location that is user-accessible.If you make aHEADrequest for the object, the response includes thex-amz-restoreheader:x-amz-restore: ongoing-request="false", expiry-date="Fri, 23 Dec 2012 00:00:00 GMT"Theexpiry-dateis the date when the temporary copy will be removed, based on the number of days you specified when you initiated the restoration.Theongoing-requestvalue offalsemeans the restoration from Glacier is complete, and the object is accessible, whiletruemeans the initial restoration operation is still in progress and the object is not yet ready for access.https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectHEAD.htmlIt isn't possible to remove the temporary copy earlier than the number of days you specified, or to make it persist longer.

As far as I know there is now way to decrease the polling frequency if you are using an event source mapping.These are all the settings you can set (source:https://docs.aws.amazon.com/de_de/lambda/latest/dg/API_CreateEventSourceMapping.html):{
"BatchSize": number,
"Enabled": boolean,
"EventSourceArn": "string",
"FunctionName": "string",
"StartingPosition": "string",
"StartingPositionTimestamp": number
}So going with a scheduled event seems to be the only feasible option.
An alternative would be to let the lambda function sleep before exiting so it will only poll again after a desired time. But of course this means you are paying for that.. So this is probably not desired. | I want to change Kinesis stream polling frequency of AWS Lambda function. I was going through this article:https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.htmlbut, no luck.

An alternative would be to leave everything as it is (from application perspective) and checkAmazonCloudWatch Logs Filter.You use metric filters to search for and match terms, phrases, or
values in your log events. When a metric filter finds one of the

value of a CloudWatch metric.If you defined your filter you can create aCloudWatch Alarmon the metric and get notified as soon as your defined threshold is reached :-)EditI didnt check the link from@Renato Gama.

I think one approach would be to use a MySQL statement interceptor:https://github.com/spullara/mysql-connector-java/blob/master/src/main/java/com/mysql/jdbc/StatementInterceptor.javaYou can use AWSXRay.beginSubsegment() in preProcess() method and then AWSXRay.endSubsegment() in the postProcess().Would be a nice addition toAWS X-Ray SDK for Javawhich is in open source.

It appears that your requirement is to compare the contents of two Amazon S3 buckets and identify files that are missing or differ between the buckets.To do this, you could use:Object name:This, of course, will help find missing filesObject size:A different size indicates different contents and the size is given with each bucket listing.eTag:An eTag is an MD5 checksum on the contents of an object. If the same file has a different eTag, then the contents is different.Creation date:This isnotactually a reliable way to identify differences, but it can be used with other metadata to determine whether you want to update a file. For example, if two files differ the object in the destination bucket has a newer date than the object in the source bucket, you probably don't need to copy the file across. But if the source file was modified after the destination file, it's likely to be a candidate for re-copying.Instead of doing all the above logic yourself, you can also use theAWS Command-Line Interface (CLI). It has aaws s3 synccommand that will compare files from the source and destination, and will then copy files that are modified or missing. | I would like to compare the file contents of two S3-compatible buckets and identify files that are missing or that differ.Should I use checksum to do it instead? | s3 - Comparing files between two buckets |

You're correct that you need to add the information toauthResponse.context. Once you do that, you can configure it as a URL Query String parameter, or Request Header, etc, via the "Integration Request" interface for your API Gateway method.Now the value which was generated in your authorizer is available to the upstream endpoint of your API Gateway.This solution is suggested (but not wholly spelled out) by the following documents:"Amazon API Gateway API Request and Response Data Mapping Reference"Map Method Request Data to Integration Request ParametersIntegration request parameters, in the form of path variables, query
strings or headers, can be mapped from any defined method request
parameters and the payload."API Gateway Mapping Template Reference"$context.authorizer.propertyThe stringified value of the specified key-value pair of the context

calling $context.authorizer.key returns the "value" string, calling

We have a WordPress implementation, and assume CodeDeploy will remove all files and replace them with the deployment package. This is its standard behavior, and I am pretty certain you cannot change that. It will want to sync the local file system with the deployment package you have provided.For this reason, consider moving the upload directory outside of the document root to account for this. Check outhttps://premium.wpmudev.org/blog/change-default-wordpress-uploads-folder/Regarding files, we moved the upload folder to /var/files, and mounted that as a EFS volume. This provides you with better durability, and makes the file system independent of any given instance.Also you should check in all files like wp-config.php on to the repo, for the same reasons - if you do not include it, then it will not be deployed.With this approach we can easily replace instances via autoscalling. You may only have one instance at this time, but at some point you will want to scale.But to answer the question directly:Yes CodeDeploy can be configured so that files are retained the way you require.You would implement a lifecycle hook script, wherebeforeInstallthe reserved files are moved to /tmp, then theafterinstallhook would move them back. extra overhead for a deploy, which is why I suggest the above approach.Seehttps://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-example.html | We have a CodePipeline set up which uses CodeDeploy to deploy the latest updates from our repository on GitHub to an EC2 instance. This works fine, except for one issue: everything we have in our.gitignorefile is deleted from the server whenever a deployment is performed.For instance, this is a WordPress site, so we havewp-config.phpandwp-content/uploadsexcluded from the repository. When a deployment runs, it deletes these files rendering the site unusable.Our desired behavior is for CodeDeploy to overwrite existing files, but also ignore any files/directories not included in the repository so they can remain untouched. By default there seems to be a step that "clears out" the deployment destination before adding the new files, but we need to skip that.Is there any setting, either in the console orappspec.yml, which will allow us to make deployments without having anything deleted? It seems like this would be a very common use case...if we can't make deployments like this then I'll have to just do all our updates via SFTP, which is pretty lame. | AWS CodeDeploy: How to stop it from deleting files? |
I'm sorry, but from your question it's not clear whether you're just experimenting with the API or if you want to write a client that calls it (as in production code).If you're just testing, you can use Postman to call the API (it supports SigV4). Detailshere.If you are writing a client, the way to go is generating the SDK from API gateway, as noted in the comments. Should that not be possible, the next best option is to use one of the language-specific SDK signers to generate the SigV4 signature.AWS4Signer, like you said, is the way to go. It should be straightforward to integrate with it, but if you can share more details of your specific use case (platform, language, where do you get the AWS credentials from, etc), people can give you a better answer.Last, if you want to generate the signature yourself,here's howthe canonical generation of signatures work. | I'm trying to invoke an api request (service: execute-api) and a Signature v4 is required. I've been going through the documentation and I see clearly this:Alternatively, you can use the AWS CLI or one of the AWS SDKs to

Sounds like the recommended way to do it is to have your server read the Origin header from the client, compare that to the list of domains you would like to allow, and if it matches, echo the value of theOriginheader back to the client as theAccess-Control-Allow-Originheader in the response.With.htaccessyou can do it like this:# ----------------------------------------------------------------------

For Apache, you can usemod_sslto force SSL with theSSLRequireSSL Directive:This directive forbids access unless HTTP over SSL (i.e. HTTPS) is enabled for the current connection.

Mu.No correct way exists, not even one that's consistent across browsers.This is a problem that comes from theHTTP specification(section 15.6):Existing HTTP clients and user agents typically retain authentication
information indefinitely. HTTP/1.1. does not provide a method for a
server to direct clients to discard these cached credentials.On the other hand, section10.4.2says:If the request already included Authorization credentials, then the 401
response indicates that authorization has been refused for those
credentials. If the 401 response contains the same challenge as the
prior response, and the user agent has already attempted
authentication at least once, then the user SHOULD be presented the
entity that was given in the response, since that entity might
include relevant diagnostic information.In other words,you may be able to show the login box again(as@Karstensays),but the browser doesn't have to honor your request- so don't depend on this (mis)feature too much. | What is thecorrectway to log out of HTTP authentication protected folder?There are workarounds that can achieve this, but they are potentially dangerous because they can be buggy or don't work in certain situations / browsers.

You can essentially do this 2 ways:The .htaccess route with mod_rewriteAdd a file called.htaccessin your root folder, and add something like this:RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=$1This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites itinternallyto what you want, without the end user seeing it. Easy, but inflexible, so if you need more power:The PHP routePut the following in your .htaccess instead: (note the leading slash)FallbackResource /index.phpThis will tell it to run yourindex.phpfor all files it cannot normally find in your site. In there you can then for example:$path = ltrim($_SERVER['REQUEST_URI'], '/'); // Trim leading slash(es)
$elements = explode('/', $path); // Split path on slashes
if(empty($elements[0])) { // No path elements means home
ShowHomepage();
} else switch(array_shift($elements)) // Pop off first item and switch
{
case 'Some-text-goes-here':
ShowPicture($elements); // passes rest of parameters to internal function
break;
case 'more':
...
default:
header('HTTP/1.1 404 Not Found');
Show404Error();
}This is how big sites and CMS-systems do it, because it allows far more flexibility in parsing URLs, config and database dependent URLs etc. For sporadic usage the hardcoded rewrite rules in.htaccesswill do fine though. | I have a URL that looks like:url.com/picture.php?id=51How would I go about converting that URL to:picture.php/Some-text-goes-here/51I think WordPress does the same.How do I go about making friendly URLs in PHP? | URL rewriting with PHP |

+50Option 1: Use .htaccessIf it isn't already there, create an .htaccess file in the Laravel root directory.

A restart isnotrequired for changes to .htaccess. Something else is wrong.Make sure your .htaccess includes the statementRewriteEngine onwhich is required even if it's also present in httpd.conf.
