Does each microservice have its own database?

Question

Yes.In a microservice architecture (MSA) services own their data. A service's database is part of its implementation and is private. The data is exposed indirectly via the service's API.

Do we need separate database for microservices?

You can use a single shared database with tables that owned by different microservices if your data is heavily related. Also in case you have strong requirements on data consistency and availiblty of a service.

Does each microservice need its own server?

Microservices are decentralized and run on different servers, but they still work together for an application. Ideally, each microservice serves a single function, which enables simple routing between services with API communication.

Should each microservice have its own repository?

Perhaps the most obvious strategy for a microservices project is to put each microservice and each shared library into a separate repository. Then set up the CI and CD pipelines for each repository, where every repository represents a unit of deployment.
