Microservices vs Monolithic Architecture

A monolith ships as one deployable unit; microservices split the same system into many small, independently deployable services.

  • Monolith — simpler to develop and deploy initially, but scales and deploys as one unit
  • Microservices — independent scaling and deployment, but adds network, data consistency and operational complexity
  • Teams usually start monolithic and extract microservices once specific parts need independent scaling
Tip

Never say 'microservices are always better' — a good answer acknowledges the added operational complexity.
