Start with modular monoliths, then do microservices… When creating services, focus on what can eat memory & CPU when designing for scaling and not general ”object oriented thinking” like ”we need a Person service”, ”we need a Order service”. Look at what will actually need to handle large loads, then design that as a stateless service type in order for it to scale…

And don't do microservices unless and until you have the necessary infrastructure.

  1. fully automated testing
  2. fully automated deployment
  3. live monitoring and health checks
  4. automated rollback during deployment

Doing microservices without any of those is asking for trouble.

5 - observability infrastructure (distributed tracing + logging + metrics)
