Virtualization technology has been around for quite a while now and especially so in leading-technology outfits. This technology has mostly developed into VPS hosting with many organizations opting to move their operations to the cloud rather than operate physical servers that require high levels of maintenance and configuration. There is one development that has, however, not been apparent in the near blanket embracing of cloud computing and VPS hosting; this is the difference between hardware level virtualization and OS level virtualization.
Hardware level virtualization was the initial technological breakthrough that saw virtualization companies virtualizes every single piece of hardware on a server in order to create a new virtual machine. This cloning event included the cloning of the server OS and all other applications running on that server. This, of course, creates a number of challenges. The first challenge is the use of resources or space on the server.
Due to the virtualization of a large number of resources, this simply moved physical server requirements into a virtual environment but retained the resource allocations. Another challenge faced is the administration of multiple OS’s that each run independently. This reduces the overall efficiency and flexibility of the server as each application has to process through two layers of OS. Finally, with the constant changes in hardware configurations in the IT space, keeping up with these changes on the virtualized environment becomes tricky.
Virtuozzo VPS however creates a completely different approach to the virtualization issue. This they achieve through the deployment of OS level Virtual Environments or VEs. These VEs are all deployed on top of a single OS and this in turn introduces a whole new set of advantages. The first advantage is the use of one OS. This in effect removes any licensing issues that may arise with using a number of virtualized copies of the same OS.
Secondly, OS level virtualization using Virtuozzo Containers makes it easy to support any and all new technologies. This is because it utilizes existing hardware and OS resources that can be reconfigured independently from the VE’s without affecting their operations. Finally, OS level Virtuozzo VPS allows for unlimited flexibility, scalability and manageability that allows for the creation of hundreds of VE’s which can all be configured and run independently yet managed from one administration hub. These advantages clearly place Virtuozzo Containers OS level virtualization solution at the very head of the virtualization pack.
