SERVERLESS FRAMEWORK
SC5 BOILERPLATE

WHY SERVERLESS (FRAMEWORK)?
▪ Ready tooling for building and deployment of Serverless
application
▪ Plug-in mechanism to enhance and customize the development
experience
▪ Capability (via plugins) to run Lambda functions locally (run & test
without deployment)
▪ Easier to debug (consume logs locally)
▪ Multi-cloud support (AWS + Azure / Google / Bluemix)

LIMITATIONS OF ”VANILLA” SERVERLESS
▪ No ability to run code / test offline
▪ Deployment produces an unoptimal package => slow ”cold start”
▪ Need to manually set up tests
▪ Need to define IAM Roles for AWS Resources (DynamoDB / SNS)
Let’s give the SC5 Serverless boilerplate a try!
