Patterns for reliable inter-service communication at scale
Microservices communication covers the patterns and technologies for services to interact reliably: synchronous (REST, gRPC), asynchronous (message queues, event streaming), and hybrid approaches. Understanding when to use each pattern and handling distributed system challenges (consistency, ordering, idempotency) is essential for modern backend development. This skill encompasses API gateways, service meshes, event-driven architecture, saga patterns, and circuit breakers that make microservice architectures production-ready.
