Generate high-scale load quickly and easily

Generate high-scale load without the need for complex infrastructure. Create tests quickly without prior knowledge of load testing tools, or run existing test scripts at scale with high-fidelity support for Apache JMeter. Streamline load testing with a fully managed service that automatically incorporates networking best practices to ensure a frictionless testing experience for public and private endpoints hosted on Azure or multicloud, on-premises, or hybrid environments.

Identify bottlenecks with actionable insights

Optimize your app's scalability and capacity by observing how a high load affects its performance. Get deep, actionable insights and recommendations from a comprehensive view of curated client and server metrics to understand and improve app performance at scale—all on a single dashboard. Visually compare load tests to see the effect of application and environmental changes, along with how tests affect all parts of your app.

Build load testing into your DevOps workflows

Easily build load testing into automated CI/CD workflows to help catch and block performance regressions early in the development lifecycle. Establish a performance baseline to compare tests against and set clear pass and fail criteria for load tests running in deployment pipelines. View load test summaries in GitHub and Azure Pipelines or get more details in the Azure portal.

Use a fully managed testing service for Azure

Experience a frictionless, cost-effective testing service that builds on other Azure services. Confidently generate load at any scale without having to worry about networking issues or overloads. Azure Load Testing automatically incorporates Azure networking best practices to avoid tests being mistaken for a security risk, and auto-abort sensors identify throttling and provide recommendations to improve runtime reliability.
