Going Serverless with Kotlin
summary
Kotlin functions compile into fat JARs and deploy to OpenWhisk, AWS Lambda or App Engine; demos use Kotson/Gson, Retrofit + RxJava on Android, Spring Boot for Lambda, and Twilio to make a phone call from a doorbell that rings phone via Twilio, which works in the live demo. Pricing examples: free up to 1M/5M requests and ~ $22 for 7M on Lambda; OpenWhisk shows the lowest cold starts while Lambda has noticeable warmup and fragmented docs, App Engine forces platform-specific code.
