CloudLinux OS - ideal for shared hosting

Dear blog readers, we warmly welcome you again to our latest update. Today we have another newcomer in the software sector and this one will surely inspire some of you. Some of you have already spoken to us about CloudLinux OS in the past and now the time has come, we are adding CloudLinux OS to our software line-up. Well, some of you know exactly what this is about, but there is bound to be one or the other information nugget that is new to the experts among you. So let's get started!

In short - what is CloudLinux OS?

As the name suggests, this is a Linux-based operating system. Of course, it is not an arbitrary basis, but a renowned distribution: CentOS. CentOS forms the basis for this and is supported with a modified OpenVZ kernel. The operating system receives all the features of the OpenVZ kernel and more. The focus here is on the Lightweight Virtual Environment or LVE for short. We'll come back to the LVE in the course of the blog post. What sets this operating system apart from others is the all-in-one component for shared hosting infrastructures. The entire system has been specially designed for the provision of virtual servers. In addition, the OS itself is relatively light on the system and only makes minimal use of the resource pool.

LVE and other features

The LVE and the associated LVE Manager are the heart of this software. Shared hosting includes managing multiple customers and their virtual instances. The LVE Manager is brought into play so that this can be carried out as easily and conveniently as possible. With this tool it is possible for the administrator to give all customers exactly the amount of resources - vCores, RAM, storage etc. - that they are entitled to. If the limits are reached by individual customers, the LVE manager intervenes and prevents this. Here the administrator can individually set the limit and also save the settings as a "package" for the future and design parameters for products.

Security is also taken care of. The most important feature in this Spate, the CageFS, ensures that customers do not have any insight into the instances or information flows from other customers. In addition, common attacks on shared hosting systems are avoided, including privilege escalations and information enclosure attacks. Speaking of "attacks" with the next security feature, namely SecureLinks, symlink attacks are repelled. Finally, HardenedPHP comes into the mix. With this integrated function, old or unsupported PHP versions can be automatically updated. This prevents security gaps that might otherwise slip under the radar. 

We hope that with this post we were able to give you a little insight into the new CloudLinux OS. You can find more information here. We are happy to answer any questions you may have. Just write an email - with your questions - to or use our conveniently Contact form.
