Introduction

Distributed Load Testing on AWS helps you automate performance testing of applications at scale to find bottlenecks before release. It simulates thousands of connected users generating HTTP requests at a sustained rate, without provisioning servers, by running containers on Amazon ECS on AWS Fargate.

The source code is at aws-solutions/distributed-load-testing-on-aws on GitHub under the Apache-2.0 licence, with about 424 stars; the most recent commit was on 4 November 2026.

1. Serverless load generation: ECS on Fargate containers.
2. Scale: Simulate tens of thousands of users, per the README.
3. Web console: Create and schedule tests.
4. Multiple regions: Run tests from several regions; see docs.
5. Results: Stored and visualised in your AWS account.
