Virtuozzo Containers is a widely used virtualization platform, which is used to make virtual servers on physical machines. Each VPS created with it is an independent software emulation of a server, which means that it has its own Operating System. The resources are also fixed, therefore when you purchase a VPS plan with certain CPU, disk space and RAM allocations, they'll always be available to you and will not be shared with another client on the server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you don't have much experience, you can control the entire server using a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, install server-side software applications and perform various maintenance tasks. You may also monitor what amount of system resources your sites are using live and all of this info will tell you if you will need upgrading while you expand your online presence. If needed, you're able to even reset the entire VPS to its original software configuration.
