Virtuozzo Containers is a widely used virtualization platform, which is used to create virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The system resources are also fixed, therefore when you get a VPS plan with certain CPU, RAM and disk space quotas, they are always available and won't be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have a lot of experience, you can control the whole server with a web-based graphical interface. With only a few clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software programs and perform numerous maintenance tasks. You can also watch what amount of resources your Internet sites are using in real time and all of this data will show you whether you need upgrading as you expand your web presence. If needed, you can even reset the whole VPS to its original software installation.
