[sf-perl] episodic cloud-based computation?

Cloud linux instances are usually billed by the hour, which doesn't match
your computing granularity of two seconds.
Here's some more details ...
- "Partial instance hours consumed are billed as full hours" on AWS
- typically it takes minutes to startup and terminate instances on
AWS, overwhelming your actual usage of two seconds.
- each vendor uses their own API for creation and termination of
instances, so the portability that you imply doesn't exist
unless you use RightScale ($500/month) or something else
- If you keep your instance around and running, then it would be billed
for the entire duration of that.
Some alternatives that involve billing at the granularity you want are:
- The closest thing to what you want is prolly Google AppEngine, but
they don't run Perl programs.
- You can get a hosting account on a large host like GoDaddy, and run your
jobs as CGI programs across their load-balanced web clusters.
- Some people have also exploited other SaaS APIs, like Salesforce.com,
as low-cost compute farms.
