Scaling with Microservices Architecture

Imagine a large, single application where all its parts are tightly connected. This is a monolithic architecture.

While simple to start, monoliths can become difficult to scale efficiently. If one small part of the application experiences high traffic, you often have to scale the entire application, even parts that aren't busy.

Microservices architecture breaks down that large monolith into a collection of small, independent services.

• Each service focuses on a single business capability (e.g., User management, Product catalog, Order processing).
• They are loosely coupled, meaning they can be developed, deployed, and scaled independently.
• They communicate with each other, often using lightweight mechanisms like APIs.
