AWS X-Ray vs OpenCensus: What are the differences?
What is AWS X-Ray? An application performance management service. It helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. With this, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors. It provides an end-to-end view of requests as they travel through your application, and shows a map of your application’s underlying components.
What is OpenCensus? A single distribution of libraries that automatically collect traces and send them to any backend. It is a set of libraries for various languages that allow you to collect application metrics and distributed traces, then transfer the data to a backend of your choice in real time. This data can be analyzed by developers and admins to understand the health of the application and debug problems.
AWS X-Ray and OpenCensus can be categorized as "Performance Monitoring" tools.
