Building a serverless application using FaaS workflows Diego Martı́n, ZHAW Abstract The present tutorial will give the participants a ba- sic understanding of the new-style workflow languages for FaaS through a tech-talk with an on-hand project. The tutorial is open to anybody interested on FaaS and FaaS composition (AKA workflows, e.g. Fission Work- flows, IBM Composer, AWS Step Functions) with no need of prior knowledge on the matter. Ideally the participants should have a basic understanding of pro- gramming and what a JSON/YAML file is, and bring a laptop in case they want to follow the on-hands part. 36
