Intermediate Topic 34 of 50 Software Engineering

Microservices

Systems composed of small independently deployable services.

How it works

Microservices split a system into small services owned by teams, each with its own data store and deployed independently, communicating over APIs or events.

Where it is used

Large organizations needing independent scaling and deployment.

Common pitfall

Distributed-system complexity: network failures, versioning, observability.

Where it fits in the course

Microservices is topic 34 of 50 in Software Engineering, rated Intermediate. It follows Domain-Driven Design. The next topic is Monolith vs Microservices.
