Hi,

VPS servers themselves are neither good nor bad. It really depends on if it's over provisioned or not. Meaning if they sell too many accounts for what the hardware/bandwidth can handle, or if the hardware is cheap and has issues it's not a good thing.

Basically think of VPS as a way to photocopy a server, including the operating system. So you buy a physical server, you include one of the virtualization platforms which is what photocopies the server. Then instead of having one instance of a server you can have X depending on what the server and bandwidth can support. I'm using the photocopy analogy as a very simple, not completely acurate example to make it understandable.

As a buyer think of hosting in 3 tiers. Least expensive and least scaleable or customizable is Shared Hosting. Next is VPS hosting. You (hope) you get more system resources for your hosting. Then the top tier is the most expensive which is dedicated server hosting. In this case you are the only user on that server. You have complete control over customizing the os to your specific needs. You have more system resources available to you, meaning you can scale larger before having to move to a faster server.

Unless you are on a very very tight budget I would always chose VPS over Shared Hosting. Dedicated servers are cheap enough now that you should be able to find a dedicated server for $40-$60 a month. Then it is all yours.

I hope this helps.
