How to deploy your BackUP hosting?

Question

linux

Good day!) The task was to sell BackUP hosting.
I need:
- I need a web interface
- Limitation on the number of files, disk, traffic, Internet speed
- Integration with WHMCS is desirable
- Access to Ftp / sftp
- Access to the shell is desirable

I looked towards ownCloud, but it is too suspicious

Answer 1

Any hosting control panel. ISPmanager for example.
