Virtuozzo Containers is a popular virtualization platform, that is used to create virtual servers on physical machines. Every VPS created with it is a separate software emulation of a server, so it has its own Operating System. The resources are also fixed, thus when you purchase a VPS plan with certain CPU, disk space and RAM allocations, they're always readily available and will not be shared with some other customer on the physical server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you do not have a lot of experience, you will be able to manage the whole server with a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software applications and perform plenty of maintenance tasks. You can also monitor the amount of resources your sites use in real time and all this info can show you if you should have upgrading as you expand your web presence. When needed, you can even reset the whole VPS to its original software installation.
