How does microservices communicate with database?

How does microservices interact with database?

Microservices database challenges 101 A monolithic application interacts with a single database. The data is shared between all application's components. By contrast, in a microservices app, data ownership is decentralized. Every service is autonomous and has its own private data store relevant to its functionality.

How do microservices communicate?

The most common type is single-receiver communication with a synchronous protocol like HTTP/HTTPS when invoking a regular Web API HTTP service. Microservices also typically use messaging protocols for asynchronous communication between microservices.

Does Microservice include 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.

Do we need separate database for microservices?

You can use a single shared database with tables that owned by different microservices if your data is heavily related. Also in case you have strong requirements on data consistency and availiblty of a service.
