Do microservices need their own database?

Should each microservice have separate database?

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.

Does microservices use single database?

Yes, it's possible to integrate a database for microservices. You can create a single shared database with each service accessing data using local ACID transactions.

Does microservices use a common database?

The use cases of using a shared database with microservices aren't common. An example could be a temporary state while migrating the monolith to microservices. The primary benefit of the shared database over per service is transaction management. There is no need to span the transactions over the services.

What database do you use for microservices?

Redis as a Multimodel Database — so microservices designers can organize their data using the data structure that best suits their performance requirements. Redis simplifies your application and data architecture.
