Summary We’ve looked at a number of different options around integration, and I’ve shared my thoughts on what choices are most likely to ensure our microservices remain as decoupled as possible from their other collaborators: Avoid database integration at all costs. Understand the trade-offs between REST and RPC, but strongly consider REST as a good starting point for request/response integration. Prefer choreography over orchestration. Avoid breaking changes and the need to version by understanding Postel’s Law and using tolerant readers. Think of user interfaces as compositional layers.
