Working with several projects on one NLU server

Hello everybody! Today I faced with a problem with handling multiple Rasa projects in one NLU server. I know that this feature was removed from Rasa. Of course I can use some technology like kubernetes but my solution must be flexible, so I don’t want to use some specific platform. Additionally, I mean that when I will change cloud platform, the code won’t have to be changed. Can you please suggest me the best practices to do it. Thanks!
