Hi @Amir_Osman
It’s been a while since you posted this. Have you reached a conclusion yet?
In terms of capabilities, there’s not much difference between Community edition & Enterprise edition; they both use the same WiredTiger storage engine, and both are capable to be used as a main database in large applications (when properly done). The main difference is that the Enterprise edition contains more “Enterprise”-needs features such as auditing, Kerberos, encrypted storage engine, and others. See MongoDB Enterprise Advanced for more information.
In terms of “can it handle a lot of users”, there are many success stories that you might want to peruse.
Alternatively you can also use Atlas to have the ops side of things managed for you. Notably, Atlas uses MongoDB Enterprise edition.
Best regards
Kevin
