Advantages and Disadvantages of CloudLinux

CloudLinux is an extremely powerful operating system built on top of the open source operating system, CentOS. We’re proud to offer it – and it works tremendously well on the infrastructure. Just recently our company switched their shared hosting servers over to CloudLinux, and have seen loads drop dramatically on their servers. Does that mean that CloudLinux is right for you?

Do I have to run CloudLinux with Whitesystem? Does CloudLinux make me a cloud provider?

Despite its name, CloudLinux is not required to be used on cloud hosting infrastructure, nor is it required to be used on our network. We offer multiple operating systems, including CentOS, FreeBSD, Ubuntu, Windows and many more. Cloud Linux can also be used on dedicated servers, and traditional VPS servers without problem. As well, using CloudLinux does not make someone a cloud hosting provider. Cloud hosting is single-handedly derived from the underlying infrastructure; typically cloud hosting requires that there multiple servers working together to provide resources on demand, however a formal definition has not exactly been defined.

Is CloudLinux right for me?

Depending on how you’re using your cloud VPS from us determines whether you really need CloudLinux. While it’s an extremely stable operating system, with numerous security enhancements it may not be something that is necessary for you to run. CloudLinux really shows its value when you’re hosting multiple websites on the same server. It does this by placing each user inside what it calls a LVE (Lightweight Virtual Environment). This LVE limits the amount of available resources to each user, which makes it so one single user cannot bring down the entire server. The actual resources limited include the CPU, RAM, and the total number of processes running by the user, like PHP scripts. The amount of resources that the user is limited to is completely definable by you, so CloudLinux actually makes it possible to offered structured shared hosting plans based of CPU/RAM usage, instead of the usual disk space and bandwidth. When a user reaches the defined resource limits, a 503 error is displayed to the website’s visitor, preventing the user from using up additional resources.

Conclusion – We have received several tickets from our customers asking why their sites are loading so slowly, or showing up some apache errors when running some applications or accessing their websites, and if we study their cases, practically 99% of them are high-demanding sites, with more than 10K daily page views, busy forums and communities with several members connected at once. If this is happening to you, do not hesitate to contact us, we can apply some changes to the LVE to make drastic performance changes and improve the speeds on your site, but always remember that you are on a shared service.

Coming up next a post about solidarity!
