Virtuozzo Containers is a widely used virtualization platform, which is used to set up virtual servers on physical machines. Every VPS made with it is an independent software emulation of a website hosting server, therefore it has its own Operating System. The system resources are also fixed, so if you purchase a VPS package with certain CPU, RAM and disk space allocations, they're always available and won't be shared with some other client on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have a lot of experience, you'll be able to manage your entire server with a web-based graphical interface. With just a couple of clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, install server-side software packages and do a number of maintenance tasks. You may also monitor the amount of resources your Internet sites use in real time and all of this data will show you if you'll need an upgrade when you expand your world-wide web presence. When needed, you will be able to even reset the whole VPS to its original software configuration.
