Virtuozzo Containers is a widely used virtualization platform, which is used to create virtual servers on physical machines. Each VPS created with it is a separate software emulation of a website hosting server, therefore it has its own OS. The system resources are also fixed, so if you purchase a VPS plan with certain CPU, RAM and disk space allocations, they are always at your disposal and won't be shared with any other client on the physical server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have much experience, you can manage your entire server through 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 applications and perform a number of maintenance tasks. You may also watch what amount of system resources your web sites use in real time and all of this data will inform you if you should have an upgrade when you expand your online presence. If needed, you can even reset the entire VPS to its original software installation.
