CloudLinux Announces 2012 Year in Review

Princeton, NJ (PRESS RELEASE) February 13, 2013 – Leading shared hosting operating system (OS) developer CloudLinux ( announced today its impressive developmental and business milestones achieved in 2012. From improvements to the CloudLinux OS to the addition of new features, these key events represent a continued commitment to helping shared hosting providers maximize performance and revenue from their servers.

The most significant new features and improvements launched in 2012 include:

  • Support for limits on disk I/O, physical memory, and number of processes

  • The new ability to define per-package limits

  • The latest version of CageFS (4.0), a per customer virtualized file system that greatly improves security

  • SecureLinks to protect against hackers that use symbolic links to access files

  • A new, simplified version of MySQL Governor

  • PHP Selector, a tool which allows customers to select a version of PHP that a customer might need

Many of these features were launched in response to customer demand or as a natural evolution of the CloudLinux OS.

“At CloudLinux, we have built a reputation of looking toward the future,” says Igor Seletskiy, Founder and CEO at CloudLinux. After all, we brought significant innovation to the world of Linux distributions with an OS that finally met the unique requirements of shared hosting companies. But it is important that we take the opportunity to look back on how we have performed and, over 2012, how we have made CloudLinux better than ever before.

CloudLinux was developed and launched with the goal of helping hosting providers make shared hosting more predictable. While a traditional OS used in shared hosting assigns hardware resources such as RAM and CPU on an as-needed basis, CloudLinux allows hosting companies to assign fixed resource allocations to each individual account. As a result, servers can contain the maximum number of shared hosting plans without the risk of a few users overusing hardware power. In 2012, CloudLinux added support for disk input-output (disk I/O) limits, physical memory limits, and a number of processes limits, giving hosting providers more ways to control how shared hosting plans are used. In addition, the much-requested feature of per-package limits became available for the first time, enabling hosting providers to sell tiered web hosting services with pre-defined resource limits.

At the core of CloudLinux, we added several new limits in 2012, as well as releasing CageFS 4.0, the latest version of virtualized per customer file system that improves server security says Seletskiy. We also added SecureLinks to protect against hackers that use symbolic links to access files. While these changes do not overhaul the existing OS our customers know and love, they refine the experience to give hosting companies even more control over their plans, along with significantly improved security. In addition to these changes, which were largely the result of requests from our users, we improved some useful tools that make up the overall CloudLinux experience, and even added some new functionality.

CloudLinux enables hosting providers to control a wide range of resource limits, but there is also a need to control other components related to shared hosting. While hosting providers require control over disk I/O, RAM, and CPU, it is also essential that dynamic web development tools, such as MySQL and PHP, can be configured and customized for each user. In 2012, CloudLinux released a new, simplified version of its MySQL Governor software, which hosting companies can use to control how webmasters use MySQL databases. In addition, CloudLinux launched PHP Selector. PHP Selector lets customers select which version of PHP they need, allowing some shared hosting customers to run their older legacy applications effectively, while neighboring accounts can use a more recent PHP release. Seletskiy believes a busy 2012 has delivered direct results in terms of company success.

Throughout 2012, we worked hard to give hosting providers even more of the features they need, says Seletskiy. Looking back, we acquired1,000 new customers with licenses, which brought us to 10,000 servers, doubling our revenue with growth of 115 percent. I believe this growth comes as a result of our determination to keep improving CloudLinux. In 2012, we also doubled the size of our development team to maintain the constant evolution of CloudLinux. The entire team is now focused on delivering the most advanced features in the industry as we move into 2013.

Since launching in 2009, CloudLinux has grown to become a leading name in the web hosting industry, with an OS that shared hosting companies and their users depend on for exceptional performance. Following such a busy and successful 2012, the team is now focused on an even more exciting 2013.
