Contrarian View: Microservices Are Dead – Use Modular Monoliths with Go 1.23 and gRPC

The software industry has spent the last decade evangelizing microservices as the gold standard for scalable, maintainable systems. But for 80% of teams, microservices introduce more problems than they solve. It’s time to embrace a better alternative: modular monoliths, supercharged by Go 1.23 and gRPC.

The Microservices Hangover

Microservices promised independent deployments, fault isolation, and technology heterogeneity. But in practice, most teams adopting microservices face a laundry list of pain points:

Distributed complexity: Tracing requests across 10+ services requires expensive tooling like Jaeger or Zipkin, and debugging becomes a nightmare.

Network overhead: Every inter-service call adds latency, serialization costs, and potential points of failure.

Operational bloat: Managing service discovery, load balancers, container orchestration, and CI/CD for dozens of services requires a dedicated platform team most…
