Microservices vs Modular Monolith
Microservices split an app into independently-deployable services; modular monoliths split internally but deploy as one.
Definition
A modular monolith keeps the application as a single deployable unit but enforces strong internal boundaries (modules, packages, domain seams). Microservices split the same application into independently-deployable services that communicate over the network. Microservices add operational complexity (service discovery, distributed tracing, network failures) but enable independent scaling and language choice per service.
Why it matters
Most teams reach for microservices too early. A modular monolith with clean internal boundaries gives you 80% of the architectural benefits with 20% of the ops cost. Split into services only when scale, organisational structure or independent-deploy needs actually demand it.
