Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Every VPS created with it is an independent software emulation of a hosting server, so it has its own Operating System. The resources are also fixed, thus when you get a VPS plan with certain disk space, RAM and CPU quotas, they are always at your disposal and won't be shared with another customer on the server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you do not have much experience, you'll be able to manage the whole server using a web-based graphical interface. With a couple of clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software programs and do plenty of maintenance tasks. You can also monitor what amount of system resources your web sites are using in real time and all of this information will tell you if you'll need an upgrade when you expand your online presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
