🧩 1. What Are Microservices (Real Definition)

A Microservice Architecture is a system design style where an application is built as a collection of small, independent services, each responsible for a specific business capability.

Each service:

• Has its own codebase
• Can be deployed, scaled, and updated independently
• Communicates with others via APIs or messages
