Greetings:
We use and recommend H-Sphere (
http://www.psoft.net/).
H-Sphere provides complete shared hosting automation.
Some of the applications you mentioned are "just" control panels. They automate a portion of hosting, but not 100%.
H-Sphere is complete shared hosting automation.
It seamlessly allows you to host RedHat Linux, FreeBSD, and Windows 200x servers distributed across multiple data centers; and manage all of those servers from one browser-based area.
It easily allows you to have various services such as mail, mySQL, postgresql, and other Internet-based services run on their own servers, and yet interact with individual servers transparently.
H-Sphere lowers licensing costs for Windows 200x as you can run qmail along with anti-virus scanning and SPAM prevention from a FreeBSD or RedHat Linux box; you can also easily have your Windows 200x customers use mySQL and postgresql as alternatives to Microsoft SQL Server.
Since moving to H-Sphere over a year ago, we’ve found our total cost of ownership (TCO) for operating a hosting business to be much lower and easier to manage.
The community forum at
http://forum.psoft.net/ is relatively active, and filled with very nice people who don’t mind sharing their years of experience.
If you want just a control panel, there’s a lot to choose from in the basket of just control panels. If you want complete shared hosting automation, then there is H-Sphere.
Thank you.
