17. what is serverless
18. (re)evolution of the cloud
19. focus on business logic less concerns about stack implementation https://medium.com/openwhisk/five-minute-intro-to-open-source-serverless-development-with-openwhisk-328b0ebfa160 bare metal IaaS PaaS functions hardware abstraction OS abstraction runtime abstraction

27. challenges
28. functions are like microservices but smaller
29. monitoring & logging debugging & diagnostics local development
30. vendor lock-in
31. latency
32. providers
