Open Source Summit North America 2017

The “serverless” architectural pattern (which has recently been made popular by AWS Lambda or IBM OpenWhisk) lets us focus on building discrete, reusable chunks of code. This pattern is particularly suited to lightweight, event-driven interactions between third-party services.

Functions-as-a-Service (OpenFaaS) is an open-source framework that allows you to package any code as a serverless function, enabling you to consume a range of web events with minimal boilerplate coding. It leverages Prometheus metrics for auto-scaling; and since it relies on Docker’s API and native orchestration, it can be deployed on any platform (private or public cloud, or even on prem’) in minutes.

In this talk, we will give an overview of the serverless pattern including use-cases; then introduce the OpenFaaS framework and show it in action. There will be live demos featuring integrations with Amazon Alexa voice assistant, Twitter, and GitHub.
