Microservices Fundamentals
Microservices are an architectural style in which independently deployable services implement distinct business capabilities and communicate over a network. They can let teams change parts of a system separately, but they add distributed-systems failure, data, and operational work.

Intro
Microservices Fundamentals
A microservices architecture splits an application into services that each implement a focused business capability. A service owns its code, runtime behavior, and usually its data. Services communicate through network APIs or messages rather than in-process function calls.
The goal is not a high service count. The goal is an independently changeable boundary where separate deployment, ownership, and scaling produce more value than the distributed-system cost. A monolith remains a valid architecture when one deployment unit and one data model keep delivery and operations clearer.
