**What is AWS X-Ray?** AWS X-Ray is a service provided by Amazon Web Services (AWS) that allows developers to analyze and debug distributed applications. It provides insights into how applications are performing by tracing requests as they travel through various AWS services and components. With X-Ray, developers can identify performance bottlenecks, pinpoint errors, and optimize application performance.

**What is Provisioned concurrency configurations in AWS?** Provisioned concurrency configuration in AWS allows users to specify a pre-defined number of instances of a function to be ready and available to handle incoming requests at all times. This helps in reducing cold starts and ensures consistent performance for functions with varying loads.
