Microservices are popular.
But most systems don’t actually need them.

After working on backend systems for more than 20 years – especially in e-commerce – I’ve seen many teams move to microservices too early.

The idea sounds attractive:
independent services, scalability, flexible deployments.

But in real business projects the trade-offs are often underestimated.

A microservices architecture introduces significant complexity:

  • distributed systems communication
  • service discovery and monitoring
  • network latency between services
  • complex deployments and infrastructure
  • data consistency challenges

For many products – especially in early and mid stages – a well-structured monolith works better.

A modular monolith can provide:

  • faster development
  • simpler deployments
  • easier debugging
  • clearer data consistency
  • lower operational overhead

In many PHP backend systems built with frameworks like Laravel, a clean modular architecture scales surprisingly far before microservices become necessary.

The real problem is not monoliths.

The real problem is poorly structured monoliths.

In practice, the best strategy is often:

Start with a modular monolith.
Introduce clear boundaries between domains.
Extract services only when scaling truly requires it.

Architecture decisions should follow product growth – not technology trends.
