What is a VPS (Virtual Private Server)
Many types of Virtualization technologies exist in the market today and all of the these technologies take a slightly different approach to the same end result, which is a large physical server sliced up into a number of smaller "Virtual Servers". Web24 provides four different virtualization technologies to customers as each have their own purpose and excel in different application.
Simplistically stated (ignoring paravirtualization, emulation and full virtualization) we can group virtualization into two categories.
Operating System Level Virtualization
Hypervisor Based Virtualization
So what is "Operating System Level Virtualization"?
OS Level Virtualization is a way of creating very efficient "containers" or "virtual environments" by utilizing a single base operating system with strong resource sharing and isolation for the guest containers. Virtuozzo VPS's look and feel just like a separate machine with its own file systems, IP addresses and software configurations. Because there are no overheads for tasks such as virtualizing CPU's and virtualizing disks to the containers (there is no virtual machine manager or hypervisor) the performance and efficiency of OS Level Virtualization is probably one of the best available on the market today.

Virtuozzo VPS Benefits
One of the most significant benefits in using a Virtuozzo VPS is that there is less duplication of resources and much more efficient ways of using them. For example, each container does not require its own private kernel because they would all be identical, a single kernel runs on the base hardware node and is used across all containers. This type of efficiency reduces RAM consumption and Disk space across all containers and is not limited to just the Kernel. As a side note, having a single kernel also allows us to ensure that all kernel security patches are applied and kept up to date across all Virtuozzo VPS's automatically. Our systems allow us to patch and update Linux Virtuozzo Nodes without the need for a host node reboot.
When to use a Virtuozzo VPS
Even if you have a dedicated server, you will still want to give serious consideration to having a virtualization layer in place. There are many benefits to this approach, and with OS Level virtualization having such a small overhead (1-3% compared with up to 20% for hypervisors) there are very few penalties. Probably the key reason that you will use a Virtuozzo VPS is for the ability to run standard applications (apache, mysql etc) in a small sized container. The memory and disk efficiencies of OS Level Virtualization will allow you to do much more with a Virtuozzo VPS than compared to a Hypervisor VPS.
