Virtuozzo Containers is a well-liked virtualization platform, that's used to make virtual servers on physical machines. Each VPS made with it is a separate software emulation of a hosting server, so it has its own OS. The system resources are also preset, so if you obtain a VPS package with certain CPU, disk space and RAM quotas, they are always available to you and will not be shared with any other user on the physical server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to manage the whole server through a web-based graphical interface. With only a few clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software and perform many different maintenance tasks. You may also track what amount of resources your web sites use live and all this data can tell you whether you'll need an upgrade as you expand your online presence. If needed, you'll be able to even reset the whole VPS to its original software installation.
