KVM vs OpenVZ: Which VPS Virtualization is Best for Your Enterprise?

December 29th, 2017

“Which virtualization is better, KVM or OpenVZ?” This question comes up often when a customer is looking into a VPS, Virtual Private Server. Once you have compared RAM and disk space specs, take a look into which virtualization web hosts offer. While there are many options to choose from, like Hyper-V, Xen, VMware, let’s examine and differentiate between the 2 current common types: KVM and OpenVZ.

 

 

The Differences Between KVM and OpenVZ

 

 

First of all, the most basic difference between OpenVZ and KVM is that OpenVZ can ONLY host Linux operating systems, while KVM is more flexible and can host Linux, Windows, and custom OS options.

Both a pro and a con of OpenVZ is the complete sharing of resources it allows. OpenVZ uses a shared kernel with a layer of virtualization on top of the actual Linux OS. Since this kernel is shared by all VPS users on this node, the kernel is not customizable. Once you have hit your allocated RAM provided to you by the host, the remaining RAM becomes a free-for-all for users on the server. This is not a problem if you run small applications, but you may be in trouble if you are running something more resource intensive.

KVM allows you to set maximum and minimum values to your resources, so that you only use the resources your applications need. This is real hardware virtualization, meaning better performance from lower requirements on the hypervisor. 100% of the RAM and disk resources are dedicated to one individual user. KVM provides a more isolated environment and gives users their own kernel.

The risk of overselling: Overselling is where a host will overcommit resources to certain accounts hoping that not every account uses up all those resources. While everything can be oversold, beware of shady hosting companies overcommitting OpenVZ systems and putting you on a system with too many containers. KVM can also be oversold, but it’s better isolated. Since OpenVZ hosts are often oversold, OpenVZ servers are typically a cheaper cost than KVM servers.

OpenVZ provides the end-user with speed and scalability, and it’s more affordable. KVM offers private virtualized hardware including network card, disk and graphics adapter, and guaranteed resources for increased reliability and customizability. KVM packages are ideal for serious resellers, game servers, small businesses, and medium-sized enterprises.

NOTE: If you are a host selling to your clients, OpenVZ is easier to set-up and maintain properly, while KVM takes much more networking knowledge. OpenVZ and their templates are more beginner friendly in that aspect. If you are simply an end-user, don’t worry and go with a managed infrastructure provider.

What is Linux VPS ?

December 24th, 2017


We’ll explain, What is Linux VPS Hosting? If you have a site that gets a lot of traffic, or at least, is expected to generate a lot of traffic, then you might want to consider getting a Linux VPS hosting package. A Linux VPS hosting package is also one of your best options if you want more control over the things that are installed on the server where your website is hosted at. Here are some of the frequently asked questions about Linux VPS hosting, answered.

What does Linux VPS stand for?

Basically, Linux VPS stands for a virtual private server running on a Linux system. A virtual private server is a virtual server hosted on a physical server. A server is virtual if it runs in a host computer’s memory. The host computer, in turn, can run a few other virtual servers.

So I have to share a server with other users?

In most cases, yes. However, this does not mean that you will suffer from downtime or decreased performance. Each virtual server can run its own operating system, and each of these systems can be administered independently of each other. A virtual private server has its own operating system, data, and applications that are separated from all the other systems, applications, and data on the physical host server and the other virtual servers.

Despite sharing the physical server with other virtual private servers, you can still enjoy the free vps benefits of a more expensive dedicated server without spending a lot of money for the service.

What are the benefits of a Linux VPS hosting service?

There are many benefits when using a Linux VPS hosting service, including ease of use, increased security, and improved reliability at a lower total cost of ownership. However, for most webmasters, programmers, designers, and developers, the true benefit of a Linux VPS is the flexibility. Each virtual private server is isolated with its own operating environment, which means that you can easily and safely install the operating system that you prefer or need—in this case, Linux—as well as remove or add software and applications easily whenever you want to.

You can also modify the environment of your VPS to suit your performance needs, as well as improve the experience of your site’s users or visitors. Flexibility can be the advantage you need to set you apart from your competitors.

Note that some Linux VPS providers won’t give you full root access to your Linux VPS, in which case you’ll have limited functionality. Be sure to get a Linux VPS where you’ll have full access to the VPS, so you can modify anything you want.

Is Linux VPS hosting for everyone?

Yes! Even if you run a personal blog dedicated to your interests, you can surely benefit from a Linux VPS hosting package. If you are building and developing a website for a company, you would also enjoy the benefits. Basically, if you are expecting growth and heavy site traffic on your website, then a Linux VPS is for you.

Individuals and companies that want more flexibility in their customization and development options should definitely go for a Linux VPS, especially those who are looking to get great performance and service without paying for a dedicated server, which could eat up a huge chunk of the site’s operating costs.
