Microservices architecture for companies in Spain: when it's worth it and when it isn't

Microservices solve real problems of scale and independent deployment — but add operational complexity that a company without a mature DevOps team cannot sustain. Architecture must fit team size, not the other way around.

• •Microservices make sense when: you have different teams deploying independently, the system has parts with radically different scalability requirements, or you need a failure in one module not to bring down the whole system.
• •The most common trap: adopting microservices out of fashion when the team has <8 developers. Orchestration complexity (Kubernetes, service mesh, distributed tracing) consumes more time than it saves.
• •The pragmatic approach: start with a well-structured modular monolith. Extract services when the monolith generates real deployment friction or when scale requires it. Not before.
