A shared hosting account is where you rent a small amount of space on a server which is shared among many other users. This is a cheap way to get started online but it has many disadvantages – you will encounter email delivery problems because of spam complaints against other sites on the same server. You will find your site's grinding to a halt when someone else does some heavy database work on your server. You might even find your site going down because of a denial of service attack against someone else hosting hacking or piracy related material on your server

By upgrading to a virtual dedicated server. A virtual dedicated server lets you run your sites as if you had your own “dedicated” server, except it is cheaper because you are really just using part of a server that has been split into multiple virtual dedicated servers.

This requires a bit of time learning the necessary Linux skills to make sure your server runs smoothly.

Many hosting providers will have a “premium” support offering that includes a bit more hand holding – this is definitely recommended if you don't have much experience with Linux, or are new to virtual dedicated hosting.

With the increased speed and bandwidth that a virtual dedicated host offers, and none of the shared hosting headaches, the move is one you will never regret.
