Introduction to Microservices Architecture
Understand the benefits and challenges of microservices, and how to design distributed systems.
What are Microservices?
Welcome to the world of microservices! This architecture breaks down a large application into smaller, independent services.
Each microservice focuses on a single business capability and runs in its own process. Think of it like a team of specialists, each handling a specific job.

Monoliths: The Traditional Way
Before microservices, many applications were built as monoliths. A monolithic application is a single, tightly coupled unit where all components (UI, business logic, data access) are bundled together.
While simpler to start, monoliths can become complex, slow down development, and be harder to scale as they grow.
