Introduction to Microservices

Microservices is an architectural style that structures an application as a collection of small, loosely coupled services. Each service is:

Focused on a single business capability

Independently deployable

Independently scalable

Potentially written in different programming languages

Potentially using different data storage technologies

Microservices architecture enables faster development cycles, better scalability, and improved resilience compared to traditional monolithic applications.

Monoliths vs Microservices

Aspect

Monolithic Architecture

Microservices Architecture

Structure

Single, unified codebase

Multiple small services

Deployment

Entire application deployed at once

Services deployed independently

Scaling

Entire application must scale together

Individual services can scale independently

Development

Single technology stack

Potentially different technologies per service

Team Structure

Often a single team

Multiple teams, each owning specific services

Complexity

Simpler architecture, complex codebase Complex architecture, simpler individual codebases
