Can microservices share the same 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.

Does each microservice have its own 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.

How data is share between microservices?

A basic principle of microservices is that each service manages its own data. Two services should not share a data store. Instead, each service is responsible for its own private data store, which other services cannot access directly.
