In which cases is it recommended to divide an application into separate microservices?

It is recommended to divide an application into microservices in the following cases:

• When the application becomes too large and complex to support as a monolith.
• If different parts of the application have different scaling requirements.
• For independent deployment and updating of individual components.
• When development teams work independently on different functional areas.
• To increase fault tolerance: a failure of one microservice does not lead to the failure of the entire application.

This approach helps improve scalability, accelerate development, and simplify maintenance, but requires organization of interaction between services and management of a distributed system.
