AWS ____ makes it easy for developers to analyze the behavior of their production, distributed applications with end-to-end tracing capabilities. You can use ____ to identify performance bottlenecks, edge case errors, and other hard to detect issues. ____ supports applications, either in development or in production, of any type or size, from simple asynchronous event calls and three-tier web applications to complex distributed applications built using a microservices architecture. This enables developers to quickly find and address problems in their applications and improve the experience for end users of their applications.
