Virtuozzo Containers is a widely used virtualization platform, which is used to create virtual servers on physical machines. Each VPS created with it is an independent software emulation of a website hosting server, so it has its own OS. The resources are also predefined, therefore if you buy a VPS plan with certain disk space, RAM and CPU allocations, they will always be readily available and will not be shared with some other client on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have a lot of experience, you will be able to control the whole server with a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot the virtual machine, set firewall rules, install server-side software and do a variety of maintenance tasks. You can also watch how much resources your Internet sites use in real time and this information can inform you if you will need an upgrade while you expand your web presence. When needed, you will be able to even reset the entire VPS to its original software setup.
