I use Amazon for various Windows and Linux servers I have in the cloud.
Couldn't be happier and it only costs me a few bucks a month.
Easy to use, very organized, comes with tons of tools and add-on services like backups. Great stuff!
Have not had any downtime yet, touch wood.
I use Godaddy for my docxfactory.com WordPress website.
It came with everything setup and installed which was great for getting started since I was new to WordPress.
I believe, it costs me about 70-80 bucks a year.
They do have surprise downtimes every month or so.
Onetime they restored the website to the previous day. Maybe it was lost. At least I know they backup
If I go to the root directory, I can see the directories of other websites although I can't access them. There's no VM for every website.
So it's probably good for small websites or getting started.
