mismi is a haskell library built on top of amazonka that is designed as a robust, higher level of abstraction to AWS interfaces. Sub-packages within mismi are built individually per AWS service to aid with haskell modularity.

This library has been used extensively in a production setting at ambiata since early 2015.

Release

The goal of the initial hackage release 0.0.1 was to provide mismi as is, with minimal change. Future work will look at removing a lot of the technical debt that has accumlated over the years will most like result in a major version change.
