An introduction to serverless and OpenWhisk for Kafka users

Saturday, July 13th, 2019

I gave a talk at Kafka Summit London this year about Apache OpenWhisk. It was aimed at Kafka users who want to know what the serverless hype is all about.

I covered:

  • a simple introduction of what serverless is for
  • an introduction to some of the serverless platforms available
  • a quick crash course in how to get started with Apache OpenWhisk

I also had a quick tangent looking into how Apache OpenWhisk itself uses Kafka internally, because I thought that was interesting!

My slides are on SlideShare if you’d like to see a higher-res version of any of them.

If this convinces you to give OpenWhisk a try, I have a post on how to get started with OpenWhisk that has all the commands you need to copy/paste to get yourself a working OpenWhisk environment connected to a Kafka source of events.


Getting started with OpenWhisk and Kafka

Apache OpenWhisk (and serverless platforms in general) are a great way to host and manage code that you want to run in response to events.
Apache Kafka topics are a great source of events.

In this post, I’ll run through a super simple beginner’s guide to writing code for OpenWhisk that processes events on your Kafka topics.
