Most applications start as monoliths โ a single, unified structure where every component is tightly coupled, like an e-commerce app with all its services bundled together. While this works initially, it often becomes unwieldy as the system scales.
Microservices: a modern architectural approach that divides the monolith into smaller, independent services.
Each service, such as a Catalog API or Basket API, focuses on a specific function. These services communicate seamlessly using tools like RabbitMQ and leverage specialized databases like MongoDB, Redis, or MySQL.
The result? Greater scalability, flexibility, and the ability to develop, deploy, and scale each component independently.
