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

Warning: The cartridges are currently liable to fail on small (free) gears due to cabal-install issue #2396.

GHC version:	7.8.4
Author:	Gideon Sireling
Home page:	http://code.accursoft.com/haskell-cloud/
Documentation:	http://code.accursoft.com/haskell-cloud/src/tip/README.md

The cartridge comes in several flavours, with just the network and text packages or a pre-installed framework:

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

Frameworks that don't have their own quickstart template use the network template (also included in every cartridge). I'll be happy to include any contributed framework-specific templates - please open an [1] with a link to your Github repo.
