In which cases is it recommended to use microservices architecture in a project?

Microservices architecture is recommended in the following cases:

• When the project is large and complex enough to be divided into independent business functions.
• If high scalability of individual components is required, rather than the entire application.
• When different parts of the system can be developed and deployed independently by different teams.
• To increase fault tolerance: the failure of one microservice does not lead to the failure of the entire system.
• If it is necessary to use different technologies and databases for different services.

Example: an online store where separate microservices are responsible for the product catalog, cart, payment, and delivery. This allows each service to be developed and scaled independently.
