PaaS (platform as a service) cloud providers generally limit you to a fixed technology stack. However, OpenShift and Heroku allow third-party extensions, which can be used to support Haskell.

OpenShift

GHC version:	7.6.3 / 7.8.2
Author:	Gideon Sireling
Home page:	https://github.com/accursoft/Haskell-Cloud
Documentation:	https://github.com/accursoft/Haskell-Cloud/blob/master/README.md

The cartridge comes in several flavours, with just the network package (GHC 7.8.2) or a pre-installed framework (GHC 7.6.3 *):

Framework	Cartridge	QuickStart	Deploy
network	manifest	quickstart	deploy
Yesod	manifest	quickstart	deploy
Snap	manifest	quickstart	deploy
Happstack	manifest	quickstart	deploy
MFlow	manifest	quickstart	deploy
Scotty	manifest	quickstart	deploy

* GHC 7.8 requires dynamic libraries for Template Haskell and Quasiquoting. OpenShift gears default to a 1Gb quota, which is insufficient for a full web framework with two copies (dynamic and static) of every library.

Heroku

GHC version:	7.4.1
Author:	Brian McKenna
Home page:	https://github.com/puffnfresh/heroku-buildpack-haskell
Documentation:	https://github.com/puffnfresh/heroku-buildpack-haskell/blob/master/README.md
