Straight forward way to replace the direct Mongo Connection with a service layer in between?

[saikiran2197]

Context:
We would like a few concurrent users to use this at once and hence wouldn't like a bunch of individual connections to our mongo instance.

Will it be straightforward to replace all instances of direct mongo get/update/delete calls with a service layer in between.

The aim would be to interact with a custom middle layer that redirects these requests to mongo

Thanks
