A Virtual Private Server (VPS) is a virtualized server. A VPS hosting environment mimics a dedicated server within a shared hosting environment. It is technically both shared hosting and dedicated hosting.
How is VPS hosting different from dedicated and shared hosting?
With dedicated servers, you rent an entire server. This is optimal for people that have very high traffic to their websites or need to set up their server in a very specific way. Not everyone needs to have a fully dedicated web server, however. If you’re just getting started with your website, you can save quite a bit of money if you rent a small portion of the server. Shared hosting is when you share a portion of the server with other users rather than rent an entire server to yourself. The technology behind VPS hosting is similar to that of VMware or Virtual Box. These programs allow you to run several virtualized operating systems on one machine. For example, your desktop may be running Windows 7, but you can also run other operating systems such as Windows XP or Linux without needing to restart your computer.
VPS hosting environments function in the same manner. While you have one physical server, you can run several different virtualized operating systems on that one server. Each virtualized operating system acts as if it was a dedicated server. This allows you to have all of the benefits of a dedicated server at a fraction of the cost.
Benefits of VPS hosting?
- VPS hosting gives you the affordability of shared hosting while at the same time giving you more power and control like a dedicated server.
- As you don’t share your OS with anyone else, there are no other websites on your server that potentially have access yo your files.
- With a VPS server, you have your own operating system. This also means that you have your own instances of all server applications such as Apache, PHP and MySQL.
- If your installing server applications that require a system restart, you can do so at any time. Even though technically you share a server with other VPS servers, your VPS server can be restarted without affecting anyone else.
- On a VPS server, you have dedicated amounts of RAM available to you at any time. Unlike shared hosting, there is no one else on your server that can utilise all the RAM when you need it the most.
