[Haskell-cafe] any cloud computing services for running Haskell?

Wed Jul 19 16:03:36 UTC 2017

Some links I like to to add to the thread:

AWS lambda
https://github.com/abailly/aws-lambda-haskell

Google Cloud functions might be an option using GHCJS

Heroku has been around for a long time:

Greetings,

Bram
