Fight cold startup times for Kotlin lambdas with GraalVM

In a live-coding session we'll see how a Custom Runtime can be implemented in Kotlin and how we can run our application as a native image that we create with the help of GraalVM.

1. FIGHTING COLD STARTUP ISSUES FOR YOUR KOTLIN LAMBDA WITH GRAALVM
3. COLD STARTUP
4. WHAT IS COLD STARTUP
5. COLD STARTUP AND THE JVM What is happening during JVM startup? JIT compilation garbage collection class loading static initialization ...

8. GRAALVM
9. GRAALVM  For existing Java applications, GraalVM can provide benefits by running them faster, ... creating ahead- of-time compiled native images. - https://www.graalvm.org/docs/why-graal/
10. GRAALVM - NATIVE IMAGES GraalVM can create native images for existing JVM- based applications native image generation employs static analysis to find any code reachable from the main Java method the reachable code is then compiled AOT into machine code the resulting executable is self-contained (contains VM components)

12. CUSTOM AWS LAMBDA RUNTIMES
14. CUSTOM AWS LAMBDA RUNTIMES open up AWS Lambda for any programming language a runtime is a program that runs the Lambda handler can be included in the deployment package

16. DEMO
17. SHOW ME THE NUMBERS Observed cold startup times
18. CONCLUSION GraalVM native images greatly reduce startup time native image also seem to improve runtime performance creating native images for an application is cumbersome native image generation is slow
