VPS.NET first to Join CloudLinux Preferred Partner Program

CloudLinux Announces Preferred Partner Program first to join initiative

ANN ARBOR, Mich., November 22, 2011 -- CloudLinux, Inc., developers of the only commercially-supported Linux server operating system made specifically for shared hosting, today announced its Preferred Partner Program with the first to join., based in Salt Lake City, Utah, with operations and data centers all over the world, is part of UK2 Group, which provides web hosting and Internet services to a million customers worldwide. With offices in London and Utah, the UK2 Group employs more than 200 staff. provides a high-performance, optimized and scalable cloud hosting service, which includes the CloudLinux OS, which it offers to all of its customers worldwide.

“The combination of CloudLinux OS with service from gives shared hosters ready access to deliver to their customers,” said Igor Seletskiy, CloudLinux CEO. “The enhanced security and stability offered by CloudLinux OS provides an unmatched experience for shared hosting customers and is proven on over 5,000 production servers running CloudLinux OS.”

"The opportunity to expand our relationship with CloudLinux made perfect sense for us,” said Terry Myers, chief evangelist, “They deliver a product that is in high demand from our customer base and offer an innovative solution addressing common problems faced in shared hosting environments."

CloudLinux cages each user account within its own Lightweight Virtual Environment (LVE), allowing system administrators to limit CPU, memory, and concurrent connections available to each tenant. LVE effectively prevents the, “bad neighbor effect,” wherein one tenant can slow or take down an entire server. By limiting abuse, shared hosters can substantially increase server density, bringing far greater efficiency to their business.

Also, CloudLinux OS includes MySQL Governor, which enables tight control over the MySQL resources available to users, and will soon release CageFS, the industry’s only virtualized file system for shared hosters. CageFS assures that user files are only available to, and viewable by, their owner. CloudLinux also offers the fastest updates in the industry, with professional support available 24/7.

Creating a CloudLinux Cloud VPS with KSplice on VPS.NET

We've already gone over what CloudLinux does, and who should be using it, but more importantly, lets go over how to maximize your use of CloudLinux. In this post, we'll walk you through the steps of creating a CloudLinux VPS, and utilizing the free KSplice license at VPS.NET.

Creating a New VPS with CloudLinux & KSplice
To get started we're going to go to the new VPS page of the VPS.NET control panel. From there we'll choose how many nodes we're going to use for this Cloud VPS. In my example, I'm going to choose 4 nodes, located in our Atlanta datacenter. I've also chose to use Snapshot and Rsync backups, along with cPanel, RVSkins, Softaculous and LiteSpeed. They're not necessary for CloudLinux or KSplice, however I certainly recommend them as they add considerable value to the hosting experience.

Once you click the create button, you're all good to go with CloudLinux. We still have a few steps to go in order to get KSplice, which allows for rebootless updates, installed.

Installing KSplice
Before we can install KSplice, we first have to license it inside of the VPS.NET control panel. KSplice is totally free, so there's really no reason not to use it. To license it, simply go to the KSplice section of the VPS.NET control panel. From there, click on the Add KSplice license and then follow the steps as outlined on the KSplice page.

Once that is complete, you've successfully setup your first CloudLinux VPS with KSplice.

Should I be using CloudLinux?

CloudLinux is an extremely powerful operating system built on top of the open source operating system, CentOS. We're proud to offer it - and it works tremendously well on the VPS.NET infrastructure. Just recently our sister company Midphase switched their shared hosting servers over to CloudLinux, and have seen loads drop dramatically on their servers. Does that mean that CloudLinux is right for you?

Do I have to run CloudLinux with VPS.NET? Does CloudLinux make me a cloud provider?
Despite its name, CloudLinux is not required to be used on cloud hosting infrastructure, nor is it required to be used on VPS.NET. We offer multiple operating systems, including CentOS, FreeBSD, Ubuntu, Windows and many more. CloudLinux can also be used on dedicated servers, and traditional VPS servers without problem. As well, using CloudLinux does not make someone a cloud hosting provider. Cloud hosting is single-handedly derived from the underlying infrastructure; typically cloud hosting requires that there multiple servers working together to provide resources on demand, however a formal definition has not exactly been defined.

Is CloudLinux right for me?
Depending on how you're using your cloud VPS from VPS.NET determines whether you really need CloudLinux. While it's an extremely stable operating system, with numerous security enhancements it may not be something that is necessary for you to run. CloudLinux really shows its value when you're hosting multiple websites on the same server. It does this by placing each user inside what it calls a LVE (Lightweight Virtual Environment). This LVE limits the amount of available resources to each user, which makes it so one single user cannot bring down the entire server. The actual resources limited include the CPU, RAM, and the total number of processes running by the user, like PHP scripts. The amount of resources that the user is limited to is completely definable by you, so CloudLinux actually makes it possible to offered structured shared hosting plans based of CPU/RAM usage, instead of the usual disk space and bandwidth. When a user reaches the defined resource limits, a 503 error is displayed to the website's visitor, preventing the user from using up additional resources.

So why doesn't it work well for single sites?
If you're only hosting a single site it simply doesn't make sense to a limit the amount of resources available to it. Usually if you just have one site on the server, you want the site to be able to use the whole server, which CloudLinux prohibits. If you're looking for the security and stability of CloudLinux, CentOS is actually a free alternative, and offers an environment just as stable and secure.

How do I get CloudLinux for my VPS.NET Cloud VPS?
If you're ready to build your first Cloud VPS with VPS.NET, simply choose the CloudLinux operating system from the "Build my VPS" screen and everything will be handled for you. If you already have the server built and are using CentOS then go to the CloudLinux templates page, and purchase a CloudLinux license for $7.50 a month. Once there, you'll be able to choose the server to license it to and install the necessary addons that let CloudLinux works its magic!

Coming up next we'll show you how to tweak CloudLinux to your exact specifications, using both command line and the cPanel/WHM plugin.
