Isn't it better to store microservice databases separately from containers?

Question

Service Oriented Architecture

Is it necessary to store microservice databases in containers? That is, one microservice + base and all this in a container, and so on. Isn't it better to store only the logic itself in the container. And bases separately not in containers? As it would not be desirable base to rigidly bind to a certain container.
How will it be more productive when the base is in a container? Or if it is outside, i.e. not in a container, will performance decrease?

Answer 1

Databases are generally not recommended to be stored in containers unless you know exactly why you need it and what you are doing.
So yes, your thoughts are correct.
In terms of performance, it depends on everything, but if you decide to do microservices, then these delays will not be so significant for you.
