I have had an account with hostingrails.com in the past. I believe
their cheaper plan is like $10 a month and they have decent support. I
am not sure I can get much cheaper than that really, but I thought I'd
ask anyway.
I want to have a server so I can show some of my websites, but I
haven't really much of a need for anything major at the moment or a
site that gets much traffic. Is anyone familiar with some cheaper
hosting plans ?
S3 for any file storage you need to do (uploads) and the database is already there -- PostgreSQL only -- so it's a migration away. The heroku gem makes the deploy process one-line-simple.
Probably other free databases available as well. Enough for small sites, and when you need a bit more you can get 256 MB at mongohq.com for $5 a month.
