Explanation:

API Manager is a component of the Anypoint Platform's control plane. The control plane in Anypoint Platform is responsible for managing, securing, and monitoring APIs and integrations. API Manager specifically provides tools for API governance, including policy enforcement, analytics, security, and lifecycle management. It allows organizations to manage APIs centrally, ensuring they adhere to compliance and security standards while providing insights into API usage and performance.

Explanation:

To track the entire lifecycle of each request across different microservices, the DevOps team should consider adopting tracing. Distributed tracing allows teams to follow a request as it travels through the various microservices, providing visibility into how long each part of the request lifecycle takes and where any bottlenecks or failures occur. Tools like Zipkin, Jaeger, and AWS X-Ray are commonly used for this purpose. Tracing complements metrics and logging by providing detailed insights into the interactions and dependencies between services.

Explanation:

In MuleSoft's Anypoint Exchange, a complete API specification in RAML (RESTful API Modeling Language) or OAS (OpenAPI Specification) format is represented as a "REST API". This asset type provides a comprehensive description of the API, including endpoints, methods, request/response structures, and other relevant details. It serves as the blueprint for implementing and consuming the API, ensuring that all stakeholders have a clear understanding of its functionality and design.

Other asset types like connectors, API spec fragments, and SOAP APIs represent different components or partial specifications, but only REST APIs provide the full specification in the mentioned formats.

Explanation:

In a microservices architecture, a service mesh manages the communication between microservices. This involves handling service discovery, load balancing, failure recovery, metrics, and monitoring. Service meshes also provide more complex operational requirements like A/B testing, canary releases, rate limiting, access control, and end-to-end authentication. By abstracting these functionalities away from individual microservices, a service mesh allows developers to focus on business logic while ensuring reliable and secure inter-service communication.
