What is the role of CloudLinux in the performance of your VPS? Let’s find out!
What exactly is it?
It’s not exactly a ‘cloud’ and it’s not exactly ‘Linux’, but it definitely does draw influence from both of these. It gives a big helping hand in the operation and management of Cloud Hosting, and in essence, it is an operating system (OS) for shared hosting companies that help provide a more stable and secure hosting environment.
CloudLinux increases the security and performance of any server, and this is accomplished by protecting individual sites against the ‘bad neighbour’ effect. Basically, this means that it will prevent a single site from crashing the server — metaphorically, it stops the one house that’s lost power from making the whole block lose power.
As well as this, when a single site starts consuming too much of the server’s resources, CloudLinux will throttle that site to allow it to continue operating up to a safe server level, whilst fully protecting your site from this ‘bad neighbour’.
Why is it great for VPS users?
CloudLinux is an effective and efficient tool in many ways. It isolates each cPanel account to its own Lightweight Virtualized Environment (LVE) and allocates a predetermined amount of resources. This isolation increases security and reliability if one of the websites is compromised with malicious scripts or has a runaway script — no other websites on the server will be affected.
CloudLinux has developed the Lightweight Virtual Environment that handles isolation and resource monitoring. This improves the density and stability of your hosting environment, ensuring that one hosting account cannot bring the whole server down.
Multiple PHP Versions
CloudLinux comes with the CloudLinux PHP Selector, that is built into the cPanel, which gives your customers the flexibility to choose the version of PHP they need. They can change the version of PHP instantly — with the click of a button.
CloudLinux also ensures that the PHP versions are updated lightning-fast, which results in secure sites and happy customers.
Enforceable Resource Limits
MySQL limits the allowable resources for each cPanel account on a global or per account basis, including CPU quota, IO, memory limits, number of processes, and concurrent connection limits. MySQL gives hosters full control over these statistics so that they can now limit abuses while allowing good customers to see what they need.
The new MySQL Governor tracks exact CPU and IO usage as it happens, so you can instantly detect abusers and throttle them.
CloudLinux has developed CageFS, which is a virtualized per-user file system, that essentially encapsulates each individual customer and prevents users from seeing each other and viewing sensitive information.
CageFS locks down the file system, preventing users viewing sensitive files and information. This also prevents a large number of attacks by malicious scripts from spreading through an entire server.
Secure Links is another security-enhancing technology that prevents the all-known symbolic link attacks. This furthers the servers’ level of security.
Overall, CloudLinux ensures that your sites and servers are as secure, stable, and reliable as they’ll ever be — at least in this day and age. With so many features that improve performance, your website(s) will be a stronghold of the online world.
