As far as I know multi-tenancy normally handled at application level either using single database or multiple databases.

But From your explanation what I am getting feel is you want to provisioning of single application on multiple servers for multiple clients each having a separate application and database instances.

I am not sure of any open source framework available but I am sure this is possible on AWS with automation scripts in shell.

If you found any such framework then please let me know

Thanks
