This "podcast episode" provides an in-depth guide for architects navigating the complexities of microservices, focusing on integration and communication patterns. It begins by addressing foundational challenges like the "Fallacies of Distributed Computing" and the CAP Theorem, before delving into the core dilemma of synchronous versus asynchronous communication. The discussion then covers various patterns, including client-facing solutions like the API Gateway and Backend for Frontends, and delves into internal service-to-service communication patterns such as the Service Mesh, Sidecar, and Ambassador patterns. It further explores the nuances of asynchronous and event-driven architectures, distinguishing between Choreography and Orchestration, and concludes with strategies for migrating legacy systems using patterns like the Strangler Fig.
