Virtuozzo Containers is a widely used virtualization platform, that is used to create virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a server, so it has its own Operating System. The resources are also preset, thus if you buy a VPS plan with certain disk space, CPU and RAM allocations, they will always be available to you and won't be shared with any other customer on the server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have much experience, you can control the whole server using a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software and do a variety of maintenance tasks. You can also track the amount of resources your sites use in real time and all this data will show you if you will need an upgrade when you expand your web presence. When needed, you will be able to even reset the entire VPS to its original software setup.
