[Haskell-cafe] [ANN] Stratosphere: AWS CloudFormation EDSL in Haskell

[Alberto G. Corona]

Very nice job.

I have tried AWS EC2 and I failed miserably since the permission system and
his intricate configurations, his paranoid security, and  their secret
formulas for pricing are beyond an average human intelligence.

It is possible to have an example stratosphere application that could
configure and run a Haskell program in one or many EC2 nodes , close the
instances and send back the results?

Are there  some elements still lacking to achieve such goal?
