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

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: https://www.christopherbiscardi.com/2014/2/2/deploy-haskells-snap-on-heroku/ Greetings, Bram On Wed, Jul 19, 2017 at 5:25 AM, Mark Fine wrote:

The performance might not be what you're looking for (there are some more performant configurations but they might not be cost effective), but it's pretty easy to get a stack project running on Heroku - this script took ~3 minutes (dominated by installing GHC on the first push) to get a simple worker running in the cloud:

I'm thinking of using cloud computing services for running my CPU-intensive parallel Haskell code, in order to get results faster. Instead of buying a faster computer, I would take advantage of existing services.

Note that my budget is small, so I need something that doesn't have a large minimum charge. I'm thinking $10 - 30 per month.

Are there any cloud services like that that run Haskell? D
