I just finished today to extract a module of my monolith to AWS Lambda in Java. I loved the experience, but first I had to configure a CI in AWS so that the build and deployment cycle was fast.

Since my function needs phantomjs, I embedded the binaries into the deployment package and by just doing that I topped up 36 MB of the 50 allowed. Transferring it from my local regular internet was a pain. Now it's nice, I push code to my dev branch, it gets picked up by the CI, tested, built and deployed. I get a notification in the IDE when the whole roundtrip is done, and with the CI in AWS it takes seconds instead of minutes. Without binaries you can still fit jackson, a few AWS clients, groovy runtime, guava and httpclient in a few megs, which is manageable.

I agree about the debugger, but authoring a function is trivial and unit tests can be written and run without considering Lambda. I miss tailing logs, CloudWatch is nice but it's far from realtime.
