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?
Most virtual hosting platforms will have a trial period in which you can test out their reliability. They will also give you a list of their high profile sites on their systems. Most keep track of the traffic hogs as it’s a great way for them to attest their own stability.
I would recommend Slicehost as I have been with them for over a year and love the control. They have an amazing panel in which you can console in, rebuild slices, and restart slices in an instance. They also allow a VERY fast and painless memory upgrade, bandwidth pooling (taking all of your accounts bandwidth into one large pool), and they allow lots of different Linux kernel OSes.
So to answer your question without sounding like a complete advertisement:
Those are things that I look for.
