The Distributed Load Testing Solution leverages managed, highly available and highly scalable AWS services to effortlessly create and simulate thousands of connected users generating a selected amount of transactions per second, originating from up to 5 simultaneous AWS regions. As a result, developers can understand the behavior of their applications at scale and at load to identify any bottleneck problems before they deploy to Production.
The solution is deployed using a CloudFormation template with a lambda backed custom resource. To simulate users from regions other than the region the solution is initially deployed in, a regional template must be deployed within the other desired regions. For details on deploying the solution please see the details on the solution implementation guide: Distributed Load Testing
source/api-services
A NodeJS Lambda function for the API microservices. Integrated with Amazon API Gateway, used to manage test scenarios.
source/console
ReactJS Single page application to provide a GUI to the solutions. Authenticated through Amazon Cognito this dashboard allows users to Create tests and view the final results.
source/custom-resource
A NodeJS Lambda function used as a CloudFormation custom resource for sending anonymized metrics, configuration for regional testing infrastructure, and iot configuration.
source/infrastructure
A Typescript AWS Cloud Development Kit (AWS CDK) v2 package that defines the infrastructure resources to run the Distributed Load Testing on AWS solution.
It also uses the AWS Solutions Constructs aws-cloudfront-s3 package to define the CloudFront distribution and the S3 bucket that stores the content that makes up the UI.
source/real-time-data-publisher
A NodeJS Lambda function used to publish the real time load test data to an IoT topic.
source/results-parser
A NodeJS Lambda function used to write the xml output from the docker images to Amazon DynamoDB and generate the final results for each test.
source/solution-utils
A NodeJS package that contains commonly used functionality that is imported by other packages in this solution.
source/task-canceler
A NodeJS Lambda function used to stop tasks for a test that has been cancelled.
source/task-runner
A NodeJS Lambda function that runs the Amazon ECS task definition for each test.
source/task-status-checker
A NodeJS Lambda function that checks if the Amazon ECS tasks are running or not.
The solution can be deployed through the CloudFormation template available on the solution home page: Distributed Load Testing.
To make changes to the solution, download or clone this repository, update the source code and then run the deployment/build-s3-dist.sh script to deploy the updated Lambda code to an Amazon S3 bucket in your account.
- Node.js 16.x or later
- S3 bucket that includes the AWS region as a suffix in the name. For example,
my-bucket-us-east-1. The bucket and CloudFormation stack must be in the same region. The solution's CloudFormation template will expect the source code to be located in a bucket matching that name.
- Clone the repository and make the desired code changes.
git clone https://github.com/aws-solutions/distributed-load-testing-on-aws.git
cd distributed-load-testing-on-aws
export BASE_DIRECTORY=$PWD- Run unit tests to make sure the updates pass the tests.
cd $BASE_DIRECTORY/deployment
chmod +x ./run-unit-tests.sh
./run-unit-tests.sh- Configure the environment variables.
export REGION=aws-region-code # the AWS region to launch the solution (e.g. us-east-1)
export BUCKET_PREFIX=my-bucket-name # prefix of the bucket name without the region code
export BUCKET_NAME=$BUCKET_PREFIX-$REGION # full bucket name where the code will reside
export SOLUTION_NAME=my-solution-name
export VERSION=my-version # version number for the customized code
export PUBLIC_ECR_REGISTRY=public.ecr.aws/aws-solutions # replace with the container registry and image if you want to use a different container image
export PUBLIC_ECR_TAG=v3.2.5 # replace with the container image tag if you want to use a different container image- Build the distributable.
cd $BASE_DIRECTORY/deployment
chmod +x ./build-s3-dist.sh
./build-s3-dist.sh $BUCKET_PREFIX $SOLUTION_NAME $VERSIONNote: The build-s3-dist script expects the bucket name without the region suffix as one of its parameters.
-
Deploy the distributable to the Amazon S3 bucket in your account.
- Make sure you are uploading the files in
deployment/global-s3-assetsanddeployment/regional-s3-assetsto$BUCKET_NAME/$SOLUTION_NAME/$VERSION.
- Make sure you are uploading the files in
-
Get the link of the solution template uploaded to your Amazon S3 bucket.
-
Deploy the solution to your account by launching a new AWS CloudFormation stack using the link of the solution template in Amazon S3.
This solution uses a public Amazon Elastic Container Registry (Amazon ECR) image repository managed by AWS to store the solution container image that is used to run the configured tests. If you want to customize the container image, you can rebuild and push the image into an ECR image repository in your own AWS account. For details on how to customize the container image, please see the Container image customization section of the implementation guide.
This solution collects anonymized operational metrics to help AWS improve the quality and features of the solution. For more information, including how to disable this capability, please see the implementation guide.
