Inside CloudLinux's New Linux-Based Cloud OS

(WEB HOST INDUSTRY REVIEW) — For the past 13-years, Igor Seletskiy has developed a series of innovative new products for the hosting industry, including the control panel H-Sphere, container-based virtualization product FreeVPS, single server control panel CP+, Web-based file manager WebShell, and website building tool SiteStudio.

Now, Seletskiy is set to launch CloudLinux (www.cloudlinux.com), the first Linux–based, commercially supported operating system optimized for shared hosting providers and data centers, at the upcoming Parallels Summit 2010 (www.parallels.com/summit).

The operating system increases server density by improving stability and reliability using isolation technology to create Lightweight Virtual Environments.

The CloudLinux proprietary environments deliver more effective resource management by reducing the amount of resources any website can use, so that no single account can slow down a whole server.

Seletskiy admits that the idea of CloudLinux isn’t entirely different than other Linux OS’s available in the industry, such as Centos or Red Hat. But where it distinguishes itself is that CloudLinux is more effective.

“If you look at our OS it’s very similar to Centos or Red Hat,” says Seletskiy. “Yet Centos or Red Hat are optimized for enterprises. Shared hosting market has specific needs like density, performance, stability that are very different in how they are perceived and executed. No one targets this market and no one has an OS for this hosting market… What I’m trying to do is create an OS that is actually better for this market.”

LVEs offers many other advantages, including better security by running all processes under the correct user and in their own lightweight container, and protects the server from hackers and poorly written scripts that take up resources for other tenants.

The proprietary isolation technology provides a range of benefits for shared hosts, including increasing the number of accounts per server, as well as reducing hardware, electricity, data center space and management costs.

As for data centers, it provides customers with a well tested, commercially supported and maintained OS, better security reduces churn and the costs associated with security support issues, and drives extra revenue via upsell to commercially supported distribution that was optimized for Web.

“We just started offering the beta,” says Seletskiy. “So far the reaction has been very good. It’s easy for us to it’s fully interchangable with Centos or Red Hat Enterprise Linux. Anyone today can take a server and within five minutes switch to CloudLinux and get much stability and density for the shared hosting environment.”

The company has been offering CloudLinux 5.4 beta 1 since January 13th, available on its website.

Cartika Hosting is just one of the customers that is bundling the OS as part of their hosting services packages.

Once officially launched at Parallels Summit 2010, CloudLinux OS will cost $14 per month for new customers, and $4 to $8 per month for partners.

At the conference and tradeshow, Seletskiy will discuss how to find the balance between the number of users per server and the load the server can carry. And as Seletskiy explains, CloudLinux will help shared hosting providers do this more effectively than any other OS on the market.

“We believe with our OS,” says Seletskiy, “hosters can double the number of hosting accounts on their servers yet have their servers more stable. And that’s one of the most critical aspects hosters look for when they are choosing an OS.”
