What is Microservices Architecture?

Microservice architecture is the approach of designing an application not as a single monolith but as small services that talk to each other via APIs. For example: payment service, user service, inventory service, etc.

Why Microservices?

• Independent Deployment: You do not need to shut down the entire system to update one piece.
• Scalability: You only scale the service that is under heavy load.
• Technology Flexibility: Different services can be built with different technologies.
• Fault Isolation: When one service has an issue, the whole system is not paralyzed (with the right design).

Challenges

Microservices require operational maturity in areas such as monitoring, logging, network communication and data consistency. Therefore, they are not "always the right choice" for every project. The right call is made based on product scale, team structure and growth targets.
