When To Use Cloudlinux On Your Virtual Private Server (VPS)

If you’re using your VPS hosting package to resell web hosting, then you probably want to look into using Cloudlinux. Cloudlinux allows you the ability to set cPanel specific limits where you can define a set amount of member, I/O usage, Inodes (files), etc. protecting the entire machine from becoming overloaded. Back in the “old days” when one customer started using too many resources, entire servers would become sluggish creating a bad experience for everyone.  This also created the need for a number of reboot requests, crushing uptime. We use Cloudlinux on both our Shared and Reseller hosting packages and publish our cPanel specific limits so our customers know exactly what to expect.  If a customer needs more resources, we recommend upgrading to our  Basic Business package or to a VPS. PHP Selector Another tremendous benefit to using Cloudlinux is their PHP selector that displays inside each cPanel account.  This allows your web hosting customers the ability to set their own versio...
