I've been giving some thought to an AWS Lambda equivalent on Joyent Triton (largely because it's open source). You'd have RethinkDB (DynamoDB), Manta (S3), your choice of queue, TensorFlow, etc. I'm generally a huge fan of the Joyent engineering ethos (not affiliated, just a fan).
Python 3.5 with DTrace probes in an AWS Lambda equivalent would be sweet.
