Monolith, Microservices or Both: Modern application development using Service Weaver
summary
Service Weaver is an open source Go framework that lets a single modular binary run locally, across processes, or as microservices without code changes; runtime features include a custom TCP transport, zero-overhead encoding, collocation to keep chatty components in-process, and routing for key affinity. Benchmarks on Google Cloud examples show up to ~40% fewer Go lines and orders-of-magnitude config reduction (1500 → 5 lines), lower CPU and p99 latency. Deploys to Kubernetes via a GKE deployer, integrates with OpenTelemetry, and demos run, deploy, trace and roll out successfully.
