Virtuozzo Containers is a popular virtualization platform, which is used to create virtual servers on physical machines. Each VPS made with it is an independent software emulation of a hosting server, so it has its own OS. The resources are also preset, so when you get a VPS plan with certain CPU, disk space and RAM allocations, they will always be at your disposal and won't be shared with another customer on the server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you don't have much experience, you can control the whole server with a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software programs and perform a number of maintenance tasks. You may also keep track of the amount of system resources your Internet sites are using live and all this info will show you whether you need upgrading while you expand your web presence. If needed, you will be able to even reset the entire VPS to its original software configuration.
