In that case, there is nothing really cloud specific here... you just need to build a standard web app or web service that accepts user input and runs some calculations in the background. Any Rails or Django tutorial will be a good start. If you expect large jobs that require a lot of number crunching in the background then running jobs in batches with Hadoop or MPI are good options. In Rails, you can use delayed_job, SQS, or any of the other work queue systems out there to handle the background tasks.

What do you mean by "billed to me"? Do you mean you pay for the costs of user's computations, or users pay you to compute an answer?
It means I get to pay for their computations. The intent is to bill them later on that service and other services.

Ok. Thank you.
