Overview

The Distributed Load Testing on AWS solution automates software applications testing at scale and at load to help you identify potential performance issues before their release. It creates and simulates thousands of connected users generating transactional records at a constant pace without the need to provision servers. The solution also allows you to run tests across multiple AWS Regions.
Benefits

Test the load capabilities of your software using independent Amazon ECS on AWS Fargate containers.
Customize your application tests by creating custom JMeter scripts.
Schedule load tests to either automatically begin at a specified date or on recurring dates.
The solution's web console contains an option to view live data for a running test.
Technical details

The diagram below presents the architecture you can automatically deploy using the solution's implementation guide and accompanying AWS CloudFormation template.
Step 1
An Amazon API Gateway API to invoke the solution's microservices (AWS Lambda functions).
Step 2
The microservices provide the business logic to manage test data and run the tests.
Step 3
These microservices interact with Amazon Simple Storage Service (Amazon S3), Amazon DynamoDB, and AWS Step Functions to run test scenarios and provide storage for the test scenario details and run test scenarios.
Step 4
An Amazon Virtual Private Cloud (Amazon VPC) network topology contains the solution's Amazon Elastic Container Service (Amazon ECS) containers running on AWS Fargate.
Step 5
The containers include a Taurus load testing Open Container Initiative (OCI) compliant container image which is used to generate load for testing your application’s performance. Taurus is an open-source test automation framework. The container image is hosted by AWS in an Amazon Elastic Container Registry (Amazon ECR) public repository.
Step 6
A web console powered by AWS Amplify is deployed into an Amazon S3 bucket configured for static web hosting.
Step 7
Amazon CloudFront provides secure, public access to the solution’s website bucket contents.
Step 8
During initial configuration, the solution also creates a default solution administrator role and sends an access invite to a customer-specified user email address.
Step 9
An Amazon Cognito user pool manages user access to the console and the Amazon API Gateway API.
Step 10
After you deploy this solution, you can use the web console to create a test scenario that defines of a series of tasks.
Step 11
The microservices use this test scenario to run Amazon ECS on AWS Fargate tasks in the AWS Regions specified.
Step 12
In addition to storing the results in Amazon S3 and DynamoDB, once the test is complete the output is logged in Amazon CloudWatch.
Step 13
If you select the live data option, the solution sends the Amazon CloudWatch logs for the AWS Fargate tasks to a Lambda function during the test, for each Region in which the test was run.
Step 14
The Lambda function then publishes the data to the corresponding topic in AWS IoT Core in the Region where the main stack was deployed. The web console subscribes to the topic, and you can see the data while the test runs in the web console.
