The CloudLinux OS
The CloudLinux OS improves server stability, security, flexibility, and allows system administrators to track heavy resource usage in shared hosting environments. Users on the dedicated server are reminded when they are at their resource limit, which avoids the penalty of shutting the entire website down. They can also track CPU, memory or disk I/O with graphs on their dashboard.
In a typical server environment, there are no hard limits in place for each user. There are of course things you can limit (PHP memory use, cron job execution, disk space, bandwidth, etc), but those aren’t the things users do that will hit you where it hurts. The majority of resource problems stem from CPU use, or disk IO, bad MySQL queries, and other runaway scripts. Before Cloud Linux, it was always a game of cat and mouse. We had to have our sysadmins get notified of the issue, login to the machine, locate the user and suspend whatever activity they were doing which was causing the problems. Pretty lame, right? We thought so too. Cloud Linux changes the game, not only for the end user like yourself but for us.

What are the benefits of using CloudLinux vs. CentOS for web hosting providers?
CloudLinux Improves Server Stability
The primary benefit of using CloudLinux is the user resource limitation features it offers. Prior to CloudLinux, it was nearly impossible to allocate specific memory, CPU, and disk I/O limits onto shared hosting customers. CloudLinux breaks each user into a tenant, similar to how virtual private server’s function, by creating a file system for each user with resource limits that the web host defines. When a user maxes out CPU resources, their web pages will be gracefully slowed down for users rather than having to suspend the site. Should they max out on memory or disk I/O, web hosts have the option to set their own custom error page to alert users of the resource usage issues. This allows dedicated hosting customers to step in and optimize their site, or plan an upgrade. No longer are users able to overload a dedicated server, which means an incredibly stable hosting environment for users.
CloudLinux provides detailed usage tracking
Not all identity thieves are looking to score your credit card information. Many will use your information to try to gain control of your site, create accounts in your name or otherwise spread digital mayhem. WHOIS privacy reduces the risks of losing your identity to those who have malicious intent.
Another way CloudLinux improves profits for a host is with the detailed usage information graphs we outlined earlier. Many web hosts gather information on their client’s resource usage and reach out to their high usage customers to offer them solutions more suited for their needs. This can generate additional products being sold to a customer like a VPS, or a shared hosting plan with additional resources. This provides alternative revenue streams for web hosts, and makes their customers more satisfied with the service at the same time.
CloudLinux is easy to use and trusted globally
CloudLinux is utilized in over 100 data centers, 2000+ web hosting companies, 25,000+ servers, and has been in development for over 5 years. This robust development cycle means a piece of software that is incredibly stable and well tested. CloudLinux offers hundreds of additional features to make providing web hosting easier.

Cloud linux Features
Lets take a look at how CloudLinux can improve a shared hosting environment.
1. Personal set of server resources for each customer
With the LVE (lightweight virtualized environment) technology in cloud linux, each customer's website account has a seperate set of allocated resources such as Memory, CPU etc. The LVE technology makes sure that these resources are not shared with any other website accounts.
2. Stable Hosting Environment
Sudden traffic spikes from other website accounts will never mean downtime for any website account or the server as a whole. Since every website account has its own allocated resources protected keeping the website running though there is a sudden spike in server resource usage from other websites hosted on the server.
3. Secured & Hardened Kernel
CloudLinux’s hardened kernel helps prevent malicious users from attacking other website accounts hosted on the server.
4. Multiple version of PHP
Cloud linux has a feature called PHP selector. It allows end users to select the specific version of PHP they need. It allows ultimate flexibility by offering all popular versions of PHP, with more than 120 PHP extensions to choose from. CloudLinux packages PHP versions 5.3, 5.4, 5.5, and 5.6. The convenient UI lets a customer switch between versions, select the extensions, and adjust PHP settings.
5. Stable Mysql Database Performance
MySQL often becomes a major headache for system admins in shared hosting environments. Keeping MySQL stable might be difficult, and customer queries can easily slow everything down. The MySQL Governor Feature of Cloud linux helps system admins to pinpoint abusers and throttle them in real time. With support from the latest versions of MySQL and MariaDB, it is a must-have for any shared host. The MySQL Governor feature tracks CPU and disk IO usage for every website account in real time and throttles MySQL queries by using same-per-user LVE limits.
With such features and the advanced technolgies of CloudLinux, maintianing a shared hosting environment stable gets easier and clients stay happy.
