What are some good questions to ask about VPS cloud hosting before signing up with them?
First of all before asking anyone - you need to ask yourself.
what are you planing to do with your hosting account.
what are you going to host,
which kind of programming languages do you require your host to support, which security / backup scheme are you planing to implement for your websites.
are your site useing SQL databases.
make your OWN checklist, of what you think you need.
search around the web for all the technical terms.
after that, you will be able to know exactly what to ask your host
I suppose that is more vitel to make sure that you need VPS. If you are getting started be aware there are shared web hosting and reseller accouts can be used as cheaper and smaller solutions
