CloudLinux: It’s definitely worth it

CloudLinux: It’s definitely worth it

CloudLinux has dramatically changed the way we oversee things, along with contributing to security, stability and reliability. We have recently installed CloudLinux onto all of our servers at localnode. We suspended installing it for a long time for it to become as good and as stable as it is today – to meet the standards our customers (you) expect.

So technically, what is CloudLinux?

Before CloudLinux, there was no restrictions for any user (besides disk space, bandwidth, PHP memorym etc). In case of any trouble, system administrators would catch the user causing problem and suspend his/her activity. We had to have our systems admins login to the machine, locate the offending user and suspend their resource hogging activity.

Now, CloudLinux comes into the scene, it will benefit not only the users but also hosting providers like us. CloudLinux enables us to host each account in such a flawless manner that we can set a resource limit for every individual account. Nobody can hijack and occupy every CPU in a server because they want to. As a user, one will get reduced loading time and minor interventions. We will have the advantage of less resource allocation for service issues, reduced disturbances and enhanced speed of user websites.

What evoked our interest in CloudLinux?

CloudLinux, created in 2009, is the first commercial operating system which is designed specifically for hosting providers. CloudLinux has been bestowed upon with enormous applause and multiple awards. It’s no wonder that today thousands of companies have incorporated CloudLinux in their systems. We believe in serving our users in the best possible way, hence we moved on to CloudLinux for a faster and more secure way.

CloudLinux Features: What makes CloudLinux so different?

LVE: LVE short for Lightweight Virtual Environment, is the technology behind the CloudLinux functioning. LVE is a collaboration of Apache modules and Linux kernel, which altogether isolates and assists in monitoring of resources on CloudLinux. So the stability of server is strengthened now, and the clients are protected from external resources.

SecureLinks: Depending upon the kernel based technology, SecureLinks add on to the security advantage of CloudLinux. This adds comprehensive protection against symbolic link attacks that are popular in a shared hosting environment.

PHP Selector: Every user runs in a personal virtual environment, so there is no longer requirement of using similar version of PHP. In the cPanel interface, users can choose between various versions of PHP. With the help of this feature you can opt for desired version of PHP running on server. It also enables anyone to modify any PHP module and even add PHP extensions.

Python Selector: Just like PHP selector, this feature enables users to opt for the desired version of Python as an application. Not only installation, even the modification of additional modules is quite easy. With the help of mod_passenger, user can get the best performance from Python.

Ruby Selector: Following with Python and PHP Selector, the Ruby selector allows end users to choose the Ruby version for applications. This also allows them to install additional modules (gems) to the application environment. Ruby Selector uses mod_passenger for optimum performance.

CageFS: CageFS is a virtualised per-user file system that works in a unique way that encapsulates each customer. It prevents users from seeing one another and viewing sensitive information about the server they are on.

However, this doesn’t mean that there is a ban on users, they can still view their files and other system-files that they need to follow. The only difference is that they can’t view each other’s files which would compromise the servers security.

MySQL Governor: Through this feature called as MySQL Governor, we can control any user who occupies more resources in shared hosting. This can be integrated in system to track all these users and throttle them.

This feature provides assistance to the system administrator by providing more flexibility over CPU, RAM etc. It also helps to manage connection issues, such as runaway PHP scripts. This feature can also diminish the number of support related inquiries.

OptimumCache: This feature comes into play when administrators have to deliver stable servers to all users. The feature can help in reducing server load by 20-30%. OptimumCache solves the issue of I/O and server memory by making a cache of duplicate files. These duplicate files create only one occurrence in memory cache. With improved speed of reading replica files and reduced memory footprint, load on hard disk gets automatically lowered. Users using web applications like Wordpress will benefit the most from this feature.

Hardened PHP: PHP is the most widely used server side script. Due to such a wide usage, it gets attacked often by hackers. Moreover, almost 85% of PHP sites are not supported by PHP.net. HardenedPHP secures all unsupported versions of PHP by patching them up along with saving them from potential vulnerabilities.

If any PHP version has become outdated and you can no longer update it, HardenedPHP will help you avoid re-writing of PHP version. This feature helps in providing more flexibility and security to all users.
