Microservices

Microservices is an architectural style where an application is built as a collection of small, independent services. Each service is responsible for a specific function and communicates with other services over a network.

For example, in an e-commerce app, one service might handle user accounts, another processes payments, and another manages orders. Each service can be developed, deployed, and scaled independently without affecting the others.

Why Teams Use Microservices

• Scale individual parts of an application without scaling everything
• Deploy features independently with less risk
• Allow different teams to work in parallel
• Use different technologies where appropriate

When Microservices May Not Be the Right Choice

• Small applications with limited complexity
• Teams without experience in distributed systems
• Projects that don’t require independent scaling or deployment

Microservices vs Monolithic Architecture

Microservices	Monolith
Multiple independent services	Single, unified application
Independent deployments	Single deployment
More operational complexity	Simpler to build and manage
