Does each microservice need to have its own database?

Contents
  1. Can two microservices use same database?
  2. Why microservices have separate databases?
You do not need to provision a database server for each service. For example, if you are using a relational database then the options are: Private-tables-per-service – each service owns a set of tables that must only be accessed by that service.


Can two microservices use same 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.

Why microservices have separate databases?

Databases should be treated as private to each microservice. This helps you to achieve consistency across different services. Event-Driven Architecture is a common pattern to maintain data consistency across different services.
