Microservices Best Practices

Microservices can accelerate delivery, but only when service boundaries and operational discipline are clear.

Start with domain boundaries

Use business capabilities to define services. Avoid splitting by technical layers, which creates noisy cross-service dependencies.

Keep APIs stable

Version intentionally, avoid breaking changes, and publish clear API contracts. Consumer trust is a performance feature.

Build resilience by default

Use timeouts, retries with backoff, and circuit breakers. A partial outage should not cascade across the platform.

Treat observability as a product

Make logs structured, propagate correlation IDs, and invest in dashboards tied to real SLOs.
