I’ve been a long time user of Debian to run my stack, and it’s been pretty resilient on my small websites. Alas, as my websites grow in traffic I wanted something to provide more security and isolation, while offering individual limitations for non-priority resources.
I first spotted Cloudlinux when researching shared hosting isolation, and it sounded like the perfect match. It offered better isolation, limitations and was very affordable. It works with Plesk and I found their entire ecosystem of tools like KernelCare and Imunify360.
I decided to give it a try, and upgraded my CentOS 7 and Plesk installation to Cloudlinux. I immediately saw performance gains on all my websites and server in general.
Cloudlinux allowed me to put limits on my non-priority websites, so when this blog gets tons of traffic as well as my smaller sites, it’ll make the smaller site have an out of resource page instead of both sites being incredibly slow.
I’m impressed with Cloudlinux, and will definitely continue to use it for hosting all production websites.
