docker-compose. Should two identical containers be used?

Question

Node.js

Good day!
A container with a NodeJS application spins on the server, performs the function of integrating 1C and the Oracle database. To be more precise, we send GET / POST requests to the server from 1C and do some manipulations with the Oracle database.
One service (transport) works with this container, and a certain programmer is responsible for the development of the functionality.
So there was a need for integration with accounting, is it worth launching a new application in a separate container? There will also be another developer here.
Or is it still limited to one and make divisions inside the application?

Answer 1

Sometimes it is useful to read about design patterns, you are currently using a microservice, and accordingly you need to raise 1 more in a new container and a separate git repository. And it doesn't even matter what programming language will be used in these services.

Answer 2

Of course, it's better to run a new application in a new container.
