I suggest using Travis to deploy CF stacks automatically based on pushed branch, dev/stage/release. I started on this in the .travis.yml and deploy-stack-travis.sh but it's not completed.
Not sure what the best way to test the client and lambdas is. Curious to hear what you come up with. I think mocking requests/responses is likely the way to go, so we don't need both client and server running to test. This would greatly simplify running tests and give lots of control over what we're testing.

I think we can easily use a local MQTT broker to mock the AWS IoT↔client protocol and a GStreamer RTP sink for testing if video stream is ok
