Serverless Swift with Apache OpenWhisk

James Thomas
Developer Advocate at IBM

Do you want to build backend applications using Swift but don't want to manage computing infrastructure to run those applications in the cloud? Enter serverless cloud platforms… 

These services allow developers to push code, rather than VMs, into the cloud. The platforms allow you to connect external event sources like API requests or message queues to functions in your code. As events occur, your code is instantiated and executed to process each request. Developers are only billed for the milliseconds needed to process each request.

In this session, developers will learn how to build Swift microservices using modern “serverless” cloud platforms. We’ll look at common challenges (and solutions) to building applications using “serverless” stacks. Exploring emerging “serverless” design patterns will give developers the knowledge to build application architectures using these new platforms.

My talk will be split into three sections:

  1. An introduction as the background of serverless computing platforms. What are they, why would you use them and what benefits do they bring over other cloud technologies likes IaaS, Containers or Paas. 
  2. The middle is then a "live coding" session using one of these platforms to build a real Swift backend application (serverless apis to create a slackbot) to show developers the techniques and skills for building serverless applications through a real world demonstration. I'll build the application, deploy to the cloud and get it running in under twenty minutes from scratch.
  3. Finally, I finish looking at the challenges of serverless development today. What are the difficulties? Monitoring, debugging, etc.... and introduce some workarounds or solutions.
