Why are microservices popular?

Microservices are trending for several reasons:

• Scalability: each service can be scaled independently, saving resources.
• Development flexibility: teams can work on different services in parallel, using different technologies.
• Resilience: a failure of one microservice does not lead to the collapse of the entire system.
• Rapid deployment: updates can be rolled out incrementally without stopping the entire application.

However, microservices require good organization, automation, and monitoring, so their implementation is justified in large and complex systems.
