Introducing a Catalog of Reusable Serverless Functions

Ever dreamed of picking a ready-to-use lambda from an open source catalog of reusable functions? Meet StackStorm Exchange. It has been serving actions to DevOps StackStorm community for years, boasting hundreds of integrations and thousands of actions. Now you can use these actions as reusable functions in the Serverless framework.

You will learn how to turn an action from StackStorm Exchange into an AWS Lambda with few lines in serverless.yml, look under the hood of how the plugin does the magic, and be encouraged to contribute your integrations.

Slides for the talk at Serverless meetup @ Heavybit May 01/2018 https://www.meetup.com/Serverless/events/249671213/
