Microservices Foundations

What microservices are, why and when to use them, communication patterns and how to adopt them.

When developing software, it starts small — a few features. But as features are added, complexity accumulates. When all this complexity stays in the same program, it's called a monolithic architecture — a monolith.

A monolith is not necessarily bad. A well-maintained monolith often has a modular architecture with abstractions that facilitate maintainability. But everything lives in the same application.

Microservices work differently: it's a collection of independent programs that collaborate to solve business problems, rather than having all business logic in the same program.
