When you need to do something technical all you have to do is contact support and let the skilled technical support operators handle the rest.

Since the 90’s VMware has been evolving. It started as a clumsy little software that used to be installed on a Windows desktop. Then from there, it changed into GSX for Windows Servers. And then again it morphed into ESX which eliminated the need for Windows and booted to a Redhat kernel. And later in version 4, it became ESXi which now runs on a custom Linux kernel.

VPS can be a perfect solution for businesses that want many of the features of a dedicated server but don't have the resources to physically host, support and maintain the server hardware. A shared environment won't offer you the same bandwidth or Web hosting space that a VPS will be able to support and there are also many more constraints on the software you can run in a shared hosting environment. In contrast, a VPS will give you the freedom to install, delete, reboot and do all the functions as if you have your own server. You also get an increased level of security as each VPS is isolated and completely separate from other Virtual Private Servers on the same physical server. The environment is secure and protected and each VPS can be rebooted or stopped independently – even if a hacker infiltrates one VPS there is no access to the others using the same physical server.

In short, you get more freedom in terms of administering and configuring your server, without the hassle of managing any physical hardware.
