The market is flooded with VPS (virtual private server) hosting options. It seems everyone and their mother has a overloaded server in his/her closet. Enterprise options always seem priced insanely high, which make the ones that are cheap and claim enterprise level seem shaky.
What do you look for in a quality VPS provider (language support, 24/hr tech, etc), and how if at all do you check their credibility?
Selecting a VPS supplier can be tricky. Some warning signs:
Out of a performance perspective there are a number of other things to consider:
To list VPS plans and suppliers that at least provide this basic information try CompareVPS.com.
You should try JoinVPS. It's cheap and enough reliable.
I've had good luck with Linode. I run Utility Mill through them. They run great, reasonable rates, and there are always people able to help you in their IRC room.
Back when I was researching, Slicehost also looked very promising but they had a waiting list at that time.
I've been with ServInt for only a month, but so far, the experience has been great. I originally grabbed a VPS from LiquidWeb after hearing some good things on forums, but was terribly disappointed. The loadtimes I was getting were awful. Though I will say that their customer service was pretty sharp. Anyways, I think you'd be making a good move by going with ServInt. So far, the performance has been wonderful, haven't really had to deal with their CS yet though. As far as unmanaged goes, I've heard Slicehost and Linode are winning that race. My 2 cents.
Availability is nice, but even cheap solutions are usually sufficient.
Thing I've wanted most since I started having sites hosted: Shell access.
It is a PAIN to do everything through FTP and web interfaces.
Oh, and if your app has PHP/MySQL/Apache/IIS/.Net/JSP/etc version requirements, you'll want to check those first.
I also should add that this made me pretty confident that I was dealing with a good company, they stood up for their competitor, when they could have easily done the opposite.
