Before we finish, let's do a quick review of what we have been through. We learned the core aspects of application instrumentation and telemetry. We gained an understanding of core AWS X-Ray concepts. We learned about AWS X-Ray as a fully managed service by Amazon, providing visualization and tracing tools. We implemented a locally hosted Dockerised microservices architecture. We reviewed how to leverage the AWS X-Ray SDK within our application. And finally, we learned how to monitor and debug our microservices architecture using the AWS X-Ray console. As a reminder, the X-Ray instrumented source code for the calculator application as presented within this course is available from Cloud Academy's public GitHub repo. Thank you for your participation! I do hope you have enjoyed this course on AWS X-Ray. Feel free to connect with Jeremy Cook with regard to any questions at support@cloudacademy.com.
