What problems does the microservices approach solve?
The microservices approach solves problems that arise in monolithic systems when an application becomes too large and hard to maintain.
1. Complexity of changes and releases
In a monolith, any update requires rebuilding and restarting the whole application. Microservices let you update individual modules without touching the rest, faster and more safely.
2. Poor scalability
In a monolith, load grows on the whole application even if only one module is overloaded. Microservices scale selectively: you can increase the capacity of only the service that needs it (for example, payments).
3. Difficulties in team development
When dozens of developers change one codebase, conflicts appear. In microservices, each team is responsible for its own service, with its own codebase and release cycle.
4. Different technologies for one system
A monolith is limited to one stack. Microservices give freedom: different services can be written in different languages and frameworks.
5. Low fault tolerance
In a monolith, a failure in one part can bring down the whole application. In microservices, the failure is isolated, and the rest of the system keeps working.
Summary: Microservices solve problems of growth, speed of change, and scaling, making the system flexible, modular, and resilient in the long run.
