Virtuozzo Containers is a widespread virtualization platform, which is used to set up virtual servers on physical machines. Every VPS created with it is an independent software emulation of a website hosting server, so it has its own OS. The resources are also predefined, thus when you buy a VPS package with certain CPU, RAM and disk space allocations, they are always readily available and won't be shared with any other client on the physical server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you don't have a lot of experience, you'll be able to control your entire server with a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot your virtual machine, manage firewall rules, install server-side software programs and perform a variety of maintenance tasks. You may also track what amount of resources your web sites are using in real time and all this data will show you whether you will need upgrading while you expand your web presence. When needed, you will be able to even reset the whole VPS to its original software setup.
