Saving data is always something very important in any kind of an application; microservices are no different. The main point is that with a distributed application, there is more flexibility to distribute our data.
There are good practices for treating storage in microservices. Obviously, patterns as CQRS are very useful, but are not always sufficient when it comes to performance. The regionalization and depreciation of data are very useful for the health of the application.
Observing the process run for the creation of containers, we can see that not only for the container of the application itself, in the case of UsersService, that there are also specific containers for the data storage layer for both, as a cache for the database itself.
