Virtuozzo Containers is a popular virtualization platform, that's used to make virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, therefore it has its own Operating System. The resources are also preset, so if you order a VPS plan with certain disk space, RAM and CPU quotas, they will always be readily available and will not be shared with another client on the server. The Virtuozzo Containers software is truly intuitive and easy to use, so even if you don't have much experience, you'll be able to control the whole server through a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot your virtual machine, set firewall rules, install server-side software applications and perform a range of maintenance tasks. You can also watch what amount of resources your sites are using in real time and all this info will inform you if you'll need upgrading as you expand your web presence. When needed, you can even reset the whole VPS to its original software configuration.
