If you have an input variable declared like this:variable "description" {
type = string
}...then you can return its value as an output value like this, in the same module where you declared it:output "description" {
value = var.description

If the first service tries to access the second service by the second service's public IP, then the traffic will go out to the Internet and back, which will destroy the network traffic's association with the origin security group.To keep the traffic inside the VPC, and to make sure the security group rules apply as intended, the first service needs to connect to the second service via the second service's private IP.If you are using a load balancer for the second service, then it needs to be an internal load balancer, not an external load balancer.ShareFolloweditedJun 19, 2022 at 6:15Simeon Leyzerzon18.9k1010 gold badges5858 silver badges8888 bronze badgesansweredMar 8, 2022 at 20:26Mark BMark B191k2525 gold badges310310 silver badges307307 bronze badges1I will try to create an internal load balancer–gamiraMar 9, 2022 at 13:28Add a comment| | I have two fargate tasks running in two different clusters, the first one is running on port 3000 and can receive requests from anyone, the second one is running on port 8080 and can be accessed only by the first one.

Actually the solution here was quite simple, although not obvious to non-Lambda experts.As described in the question, the first step was to build the package library.pip install --target ../package/python -r requirements.txtHowever, when building the Lambda usingsam build -uthe same 'requirements.txt' file is used and the required dependencies were again being installed, this time as part of the app.So all I had to do was remove the requirements that I wish packaged in a separate layer and rebuild.

I noticed you have a fresh install -- fresh installs do not have software listening over HTTP by default.If there is no application listening on a port, incoming packets to that port will simply be rejected by the computer's operating system. Ports can be "closed" through the use of a firewall, which you have disabled, therefore the ports are open just unresponsive which makes them appear closed.If the port is enabled in the firewall in the terminal usingsudo apt-get install ufw
sudo ufw allow ssh
sudo ufw allow https
sudo ufw allow http
sudo rebootand enabled in the AWS console as a rule, the port is open and just not responsive so it's seen as closed. By installing either nginx or something that binds to port 80, external requests to that port will be connected successfully, and the port will therefore be recognized as open. The reason ssh is recognized as open is because 1. it has firewall transparency, and 2. it is always listening (unlike port 80!).
Before installing nginx even though ports are allowed through the firewall:sudo apt-get install nginx
sudo ufw allow 'Nginx HTTP'
sudo systemctl status nginx(more nginx info)After:Simple port tester toolhereShareFolloweditedMar 4 at 8:28CommunityBot111 silver badgeansweredDec 9, 2021 at 7:35Keegan MurphyKeegan Murphy79755 silver badges1515 bronze badgesAdd a comment| | I want to open port 80 to allow HTTP connections on my EC2 server.

I heard once that Amazon Prime Video uses CloudFront and they have videos that get cached in CloudFront, but I have never seen any actual figures published about the size of the cache.My assumption is that CloudFront cacheseverything, but older stuff falls off the cache when they run out of space. So, if your videos keep getting watched, they'll stay in the cache.CloudFront uses a Regional model, so if a cache at the edge does not have content (eg Manchester, England) it will go the cache in the nearest Region (London). If that cache is missing the content, it will go back to the source. So, this means that several edges can benefit from a nearby regional cache, which is more likely to have content since it would receive more 'hits' (and I assume it would also have a larger cache).If you want to measure how well CloudFront is caching, you candetermine whether something was served from the cacheby looking forX-Cache: Hit from cloudfrontorX-Cache: Miss from cloudfrontin the page headers.CloudWatchcan also provide aCache Hit Rate, which provides the proportion of requests that were served from CloudFront edge caches instead of going to origin servers for content.ShareFollowansweredJul 6, 2021 at 10:11John RotensteinJohn Rotenstein254k2626 gold badges408408 silver badges498498 bronze badgesAdd a comment| | How much maximum cache space allowed per distribution in AWS CloudFront CDN per each POP?For example:If I run a 4K video sharing website and each video size is approximately 2GB.100K users came from same city in one day to watch videos (from 10K video collection) on website.So, CloudFront need to serve 10,000 different videos for 100K users and each video size is 2GB.

You can't. It is not even defined in AWS CLI/API (https://docs.aws.amazon.com/Route53/latest/APIReference/API_Operations_Amazon_Route_53.html).However, you are kind of protected because deletion of a domain in Route 53 requires confirmation as AWS states:Important: When we receive a request to delete a domain, ICANN
requires us to get confirmation from the current registrant contact.
We will send an email from[email protected]or[email protected]to the registrant contactI would not give much importance to the scan result of that tool, since what would actually keep your domain safe against unwanted deletion, renew or updates is securing your AWS account, for instance, setting 2FA (two factor authentication) for your root user. If your access to AWS is not for your personal account (like your own website or experiments) then it is strongly recommended that you avoid login in with the root user for common tasks, and instead create IAM Roles based on policies so each (group of) user has a specific task.Note that only clientTransferProhibited (Transfer Lock) is enabled in Route 53 because it refers to an operation that can be (maliciously) initiated externally and not only within Route 53.ShareFolloweditedJun 29, 2021 at 23:27answeredJun 29, 2021 at 4:45Guillermo Garcia MaynezGuillermo Garcia Maynez8611 silver badge33 bronze badges1This is essentially the same answer I got from AWS support: not supported in AWS route 53–qUEnbcArJun 30, 2021 at 17:52Add a comment| | An external vulnerability scanner flagged a domain I manage through AWS Route 53 as not having theclientDeleteProhibited,clientRenewProhibited, andclientUpdateProhibitedEPP status codes set.I confirmed this via whois:Good whois entry for compliant domain# whois.registrar.amazon.com

You can implement addEventListener in use effect like this.import {AppState} from 'react-native';
useEffect(() => {
setTimeout(() => {
AppState.addEventListener("change", _handleAppStateChange);
}, 2000);
return () => {
AppState.removeEventListener("change", _handleAppStateChange);
};
}, []);Here you define your _handleAppStateChangeconst _handleAppStateChange = (nextAppState) => {
if (
appState.current.match(/inactive|background/) &&
nextAppState === "active"
) {
console.log("App has come to the foreground!");
//clearInterval when your app has come back to the foreground
BackgroundTimer.clearInterval(interval)
}else{
//app goes to background
console.log('app goes to background')
//tell the server that your app is still online when your app detect that it goes to background
interval = BackgroundTimer.setInterval(()=>{

ThattotalRetryDelayvalue would be most useful to you if your nodejs program were not sending multiple concurrent requests to the API.

If you google "SaaS Multi-tenant Storage Isolation" You'll find a number of resources on this topic.

As your domain name is resolving to the IP address the IP address will still need to allow ingress into the IP.For this reason the change will need to happen within the host.Depending on the web server technology you are using (such as Apache or Nginx) the first host file that loads is served if no other host configuration is matched.If you add the secondary vhost for your domain ensuring you explicitly reference the domain, then in the default host rather than serving your application return a 403 instead this will prevent bypassing your domain name.More information is available in the following links:Apache VHOST configurationNginx configurationShareFollowansweredFeb 7, 2021 at 10:56Chris WilliamsChris Williams33.5k44 gold badges3434 silver badges7171 bronze badgesAdd a comment| | I have a wordpress website hosted on AWS Lightsail.

There is none, you can use the index management policy if you like, which will operate at the index level, not at the doc level. You have a bit of wriggle room though in that you can create a patterndata-*and have more than 1 index,data-expiring-2020-...,data-keep-me.You can apply a template to the patterndata-expiring-*and set a transition to delete an index after lets say 20 days. If you roll over to a new index each day you will the oldest day being deleted at the end of the day once it is over 20 days.This method is much more preferable because if you are deleting individual documents that could consume large amounts of your cluster's capacity, as opposed to deleting entire shards. Other NoSQL databases such as DynamoDB operate in a similar fashion, often what you can do is add another field to yourdocssuch asdeletionDateand add that to your query to filter out docs which are marked for deletion, but are still alive in your index as a deletion job has not yet cleaned them up.

By using the--queryparameter you are able to modify the response you will receive back from the AWS API.This feature can be very useful in scenarios where you want to programmatically use the AWS CLI to extract parts of a response, in your example this is extracting theKeyMaterialattribute from the response but it could also be used to filter and extract attributes based on their values.For you usecase it means you will be able to get the plain text of the key and pump it straight into a text file rather than manually performing copy and paste (although this is benefited by the--outputflag).For more information take a look at theControlling command output from the AWS CLIdocumentation.ShareFolloweditedOct 24, 2020 at 15:22answeredOct 24, 2020 at 15:14Chris WilliamsChris Williams33.5k44 gold badges3434 silver badges7171 bronze badgesAdd a comment| | I came across the following command to create AWS SSH key-pair but failed to understand what "--query" parameter is doing here.aws ec2 create-key-pair --key-name MyKeyPair --query 'KeyMaterial' --output text > MyKeyPair.pemCan someone please explain me the significance of--queryparameter? | AWS SSH Key Pair Creation |

Or maybe that there is just no real pitfall and that the best approach is 'problem' --> 'solution' when those problems come up.I don't think it is an opinion-based question because I/O intensive database, queue systems, server calculation, etc have clearly some technical consideration in that kind of configuration.And to give you some example of problems that I think large scale social app can encounter, there is Facebook engineers with their early latency problem or Twitter engineers with their Bieber problem.I was able to avoid the first pitfall that Netflix couldn't avoid, which is not using Cloud and trying to build their own servers infrastructure at this scale. | Code and servers pitfalls to avoid when launching social application with many interactions? |
You probably have already found the solution, but I am leaving this for future visitors looking for the answer.Recently Amazon Cognito has started supporting the verification link as well with custom message template. Unlike verification code, the users won't be stuck if the window is closed as they can always click the link from the email.You can choose verification by email and under "Message Customization", use "Link" for "Verification Type". In your message template, you can use the placeholder{##Click Here##}for the actual link.If you are using terraform you can usethis resourcewhich would look something like:verification_message_template {
default_email_option = "CONFIRM_WITH_LINK"
email_subject_by_link = "Verify your account"
email_message_by_link = <<EOF
Hello,<br/><br/>
Thank you for signing up.<br/><br/>
<strong>Here is your Verification Link: {##Click Here##}.</strong><br/><br/>
Thanks,<br/>
EOF

Solution is:resource "aws_cloudwatch_metric_alarm" "cloudwatch_metric_alarm_down" {
alarm_name = "${local.name}-ecs-alarm-down"
comparison_operator = "LessThanOrEqualToThreshold"
evaluation_periods = var.evaluation_periods_down
threshold = var.downscale_threshold
metric_query {
id = "e1"
expression = "FILL(m1, 0)"
label = "0 if NoData"
return_data = "true"
}
metric_query {
id = "m1"
metric {
metric_name = var.metric_name
namespace = var.env_name
period = "60"
stat = var.metric_statistic
}
}
alarm_actions = [aws_appautoscaling_policy.down.arn]
depends_on = [aws_appautoscaling_policy.down]

Workflow of autoscaling should be like this:if in 1 minute we receive more than 10 values we need scale upwait 10 minutesif no values we need to scale downScale up works perfect but scale down doesn't work at all. We are getting this:Failed to execute action arn:aws:autoscaling:eu-central-1:BLA-BLA-BLA-fargate-scale-down.

Check the AWS docs out here for the fix on windows :https://docs.aws.amazon.com/codecommit/latest/userguide/troubleshooting-ch.htmlIt should be due to credential helper doesn't connect to the credentials properly for some reason.(I had the same issue on Mac. Once the aws credential helper and osxkeychain credential helper were restored as instructed in the doc, things were working fine.)See if that helps. - CheersShareFolloweditedSep 14, 2020 at 8:44answeredSep 14, 2020 at 8:29DhammikaDhammika54144 silver badges1010 bronze badgesAdd a comment| | I am trying to set up My AWS code commit to my local system.I am trying to clone the repogit clone https://git-codecommit.us-east-1.amazonaws.com/v1/repos/lambda-pipeline-repowhen I tried to do that I get this window where I enter my IAM user credentials.Soon after this, I getCloning into 'lambda-pipeline-repo'...
