Knowing that your application is well-architected, scalable, and that introducing new features or components won't introduce bottlenecks is challenging. Not only do you need to understand the constraints of your application architecture on day 0, but you need to continually check that your infrastructure and automation will cope with an increase in load. Key business stakeholders will want to know much load your application can be under while remaining performant, and they'll look to you for answers to questions such as:

- How many users can our application support?
- Do you know what the current bottleneck of the application is?
- You've told me we've got this fancy "auto scale" turned on for our cloud components, but have we tested it works as expected?
- We're about to introduce a new feature to the application which required additional infrastructure. Are you confident this won't introduce bottlenecks to the performance or scalability of the application?

If you'd struggle to answer some of these questions with data to back up your statements, then this is the session for you!

Azure Load Testing is a (preview) managed service allowing you to easily generate high-scale load to test your applications. Your application doesn't need to be hosted in Azure, but if it is, you can gain additional insights into how the components of your applications are performing when the application is under load.

In this session, we'll start by understanding how the Azure Load Testing service works, and then move into some hands-on demos starting with a basic load test, understanding Jmeter, load testing private endpoints in Azure, and integrating the Azure infrastructure being load tested with Azure Monitor for end-to-end observability. Whether you're an architect, engineer, administrator, or developer, you'll leave the session with a fundamental understanding of what the Azure Load Testing service can provide for you, with the practical knowledge to start using the service to test your application performance and scalability.
