Azure Load Testing is a subscription-based service designed for developers and testers to generate high-scale loads and identify performance bottlenecks in applications. This fully managed service allows users to create tests quickly without requiring extensive knowledge of load-testing tools, or they can upload existing Apache JMeter scripts. The platform supports continuous improvement through automated CI/CD workflows, enabling users to optimize scalability and capacity by observing application performance under high-load conditions.

The service provides deep insights through a single dashboard that showcases curated client and server metrics, helping users understand and enhance app performance at scale. Azure Load Testing also allows for visual comparisons of load tests, enabling users to assess the impact of application and environmental changes effectively. With support for various organizational types and a free trial available, it's suitable for a wide range of users looking to improve their application's reliability.
