Haskell for Devops
This page is for collecting information and collaborating on the general idea that Haskell is a great tool for devops. The original mailing list thread covers a lot of information, but hopefully the following points will be a good summary:
Devops is a broad term that can mean many different things. We're going to adopt the following definition provided by Arnaud Bailly:
The essence of DevOps as I think Patrick Debois has explained it for years is exactly to be sure there is NO separation between the two areas you are mentioning, viewing the Development to Operations as a continuum.
This covers things from config management, to CI systems, to web services.
Haskell's ability to write low-runtime-dependency, high performance applications using its wide array of composable libraries makes it appealing for putting together various devops services.
Haskell plays nicely with existing devops tools like Docker and Ansible, as demonstrated by how people in the Commercial Haskell Special Interest Group are using Haskell.
Please feel free to expand on this.

Warp in a tweet. Run a high performance static file server with a single line:
docker run -it --rm -p 3000:3000 -v /var/www/html:/var/www/html:ro snoyberg/warp /usr/bin/warp -d /var/www/html
Ideal Haskell Devops Stack
These are not all written in haskell.
- Build Pipeline
- Stack Creation
- Stack Managment
- Runtime Control / Remote Execution (How to change state after the stack has been deployed, salt does this): ?
- System Monitoring: ?
- Application Monitoring: EKG
- Metrics Consolidation: Riemann?
- Log Collection: ?
- Log Aggregation: ?
- Log Archiving: ?
- Long Term Log Analysis:
- Real Time Log Analysis: Riemann?
