Virtualized file system for shared hosters cages each customer within its own virtualized file system.

CloudLinux Inc., a software company dedicated to serving the needs of hosting service providers, yesterday announced the release of CafeFS 3, a virtualized file system for shared hosters that cages each customer within its own virtualized file system.

The company says that CageFS becomes part of CloudLinux OS at no additional charge. CloudLinux OS, a commercially-supported Linux OS made specifically for shared hosting, substantially increases server stability, density and security to bring far greater efficiency to the web hosting business. CloudLinux OS is fully-compatible with Red Hat Enterprise Linux (RHEL) and CentOS, as well as being integrated with Parallels Plesk Panel and most other major control panels.

It articulates that to eliminate potential security issues, CageFS ensures that users will not see any other users and will have no way to detect the presence of other users on the server. As an additional precaution, users are not able to see server configuration files, such as Apache config files. Meanwhile, the user's environment is fully functional and is not restricted in other ways. Beyond providing safe web hosting, CageFS offers the necessary functionality and security to provide safe IRC, shell and backup hosting.

"This is all part of our mission to deliver technology specifically developed for the needs of shared hosting companies," said Igor Seletskiy, CloudLinux CEO. "Each shared hosting site gets security on par with VPS, but without all the VPS administrative overhead. That in turn leads to a better experience for the customers, and better margins for the hosters."

"Parallels strives to help service providers to be more efficient and secure," said John Zanni, Parallels VP of Service Provider Marketing and Alliances. "We are very happy to collaborate with CloudLinux to improve the shared hosting experience."
