How do microservices share databases?

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.

Does each microservice need to have its own database?

The short answer is yes. If two or more microservices were to share persistent data then you need to carefully coordinate changes to the data's schema, which would slow down development. ... There are a few different ways to keep a service's persistent data private.

Should microservices share data?

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.

How are databases shared?

A Shared Database allows you to store your documents in your favorite relational (SQL) database rather than on the file system. This means that multiple users can concurrently use the same synchronized storage location without any problems.

How do I manage multiple databases in microservices?

Create a single database for different microservices is anti-pattern, then the correct way is to create a database for each microservice.

Is a shared database in microservices actually an anti pattern?

Indeed it is. It is analogous to having each microservice storing data communicating with the other services using a big API, namely the database schema.
