## AI overview

This article explains how microservices replace a tightly coupled monolith with independently deployable services aligned to business capabilities. It covers benefits such as independent scaling, fault isolation, team autonomy, and technology flexibility, while noting the added costs of communication, observability, operations, and data management. It recommends using microservices when domain complexity and scale justify the operational cost, organizing services around bounded contexts, and extracting one domain at a time.

## Source excerpt

Microservices trade deployment simplicity for independent scaling, fault isolation, and team autonomy, and they only pay off once domain complexity and scale justify the operational cost. Align services to bounded contexts, give each its own data store, and extract one domain at a time rather than splitting by technical layer.
