   If you intend having a small number of choices for the whole system
(i.e. only one Ubuntu configuration, only one Windows configuration,
only one Fedora configuration), and simply want to be able to deploy
that configuration repeatedly, then many VM providers will give you
the ability to build deployment images.

   If you want more flexibility (i.e. you might want an Ubuntu
configuration with Postgres installed one time, and one with RabbitMQ
installed a second time), then you're looking more into the area of
configuration management systems like Puppet or Chef or Ansible. I use
Puppet -- it's a pain in the arse, but that's more to do with (a) the
problem space: completely automating an installation and site-specific
configuration for a bunch of arbitrary packages takes time and effort,
and (b) the fact that I'm not really a practised sysadmin and don't
much enjoy it. For simple things (installing packages, or managing
basic configs of popular and well-known packages like Apache or
Postgres), Puppet is pretty straightforward, and you can get
_something_ working quickly. It's probably no more effort in the long
term than writing and maintaining a bunch of complicated shell
scripts, and ultimately more reliable.

   Hugo.

But I used the "free" tier, thought I was being careful, and got slapped with $60 in charges from network traffic before I could shut things down. There is no way to tell Amazon "I would rather go offline than pay $x", so a misconfigured cron job or traffic spike (DDoS?) that happens while you're asleep is basically guaranteed to cost you.
