Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.[3]
Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.
Another way you can customize your VPS to your specific needs is with your choice of Linux operating systems. Select from the best versions of Ubuntu, CentOS, Fedora, Debian, Gentoo or Slackware. If you're in the middle of a project and want change to a different version or a different OS entirely, you can change and re-load your operating system on demand whenever you want!
Your web projects come in all shapes and sizes. Shouldn't your VPS meet your needs more closely? Your project may need additional disk space or data transfer while maybe you don't need so much RAM. Don't get stuck paying for for resources you don't want or don't need from a one-size-fits-all VPS provider. We've got your covered! Design your perfect VPS at A2 Hosting!

The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
