Analyzing and debugging production distributed applications built using a service-oriented or microservices architecture is a challenging task. In this session, we will introduce AWS X-Ray, a new service that makes it easier to identify performance bottlenecks and errors, pinpoint issues to specific service(s) in your application, identify the impact of issues on users of your application, and visualize a request call graph and service call graph for your applications. We will show interactive demos, and code samples for the demo will be available to all session attendees.
