Microservices Architecture

An architectural style that structures an application as small, independently deployable services communicating over APIs.

Definition

Each service owns its data and can be scaled and released independently, enabling team autonomy and faster delivery. Trade-offs include distributed-system complexity, network latency, and observability needs, unlike a monolith.

Example

An e-commerce app splits catalog, cart, and payment into separate services deployed on Kubernetes.

Exam tip

Microservices increase deployment independence but require distributed tracing, service discovery, and resilience patterns.
