[DISCUSS] AWS IAM-based client authentication

[Joel Shepherd]

Hi - I have a side project that provides client- and node-side Java 
plug-ins to enable client-to-node authentication based on AWS 
identities. This would, for example, enable clients to use EC2 instance 
roles to authenticate to Cassandra nodes, or use ordinary IAM 
keys/secret keys. The client needs to be able to obtain valid IAM 
credentials to sign a request, and the node needs to be able to connect 
to a public AWS Security Token Service (STS) endpoint. There are no 
other required AWS dependencies, and (I believe) no changes required 
driver or node code: just minor configuration updates.

I'm seeking help in reviewing the concept and code. I'm new to this 
community,  so I'm looking for suggestions on how to best engage you on 
this.

The code (which is not quite production-ready) is in two private GitHub 
repos which I'm happy to grant access to for early review. I can also 
provide documentation on the approach: not sure whether that's best 
shared via this thread, a CEP, repo documentation ... suggestions wanted.

Thanks: I'd appreciate any and all help in making these plug-ins 
available to the community.
