Can microservices share a database?

Is it a good idea for microservices to share a common database?

Microservices with shared databases can't easily scale. Changes related to the database could impact multiple services. Besides, microservices won't be independent in terms of development and deployment as they connect to and operate on the same database.

Should two microservices share a database?

You are not likely to benefit from a Microservices architecture if all the services share the same database tables. This is because you are effectively tightly coupling the services. If a database table changes all the services will have to change.

How do microservices interact with database?

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.

Should microservices have separate databases?

Each microservice should have its own database and should contain data relevant to that microservice itself. This will allow you to deploy individual services independently. Individual teams can now own the databases for the corresponding microservice.
