KVM’s popularity has been moving up on the list of virtual machine software’s due to its success with OpenStack. Marrying the 2 products together gives similar functionality as VMware vSphere, although there are some limitations with hosting Windows VMs, which are now taken care of by OpenStack’s ability to also support Hyper-V and ESXi.

Our VPS Hosting plans all come with a high availability feature that essentially takes your VPS container, and empowers it with a cloud infrastructure. How does this work? We put a premium on your server's uptime, so we created an infrastructure of redundant hardware clusters that provides your partition with real-time redundancy. If for some reason there is an error on your server, there is another server in the cluster with that backup information ready to spin up. We utilize Virtuozzo, a virtualization solution built on top of OpenVZ.
Self-Managed VPS customers have to make sure everything works the way they configure them and perform updates themselves. Obviously, this is not a job for novice users. It is probably not even a job for someone who does not feel comfortable managing services and scripts themselves. If in doubt, you should probably stick with a Managed VPS product and focus, instead, on growing your business and optimizing your site.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
