Showcase to coordinate serverless functions

This demo implements the classical trip booking Saga example with various serverless functions and different ways of orchestrating them.

I use this for certain talks:

• Serverless Days Hamburg 2019: https://www.slideshare.net/BerndRuecker/serverless-days-2019-lost-in-transaction
• AWS Community Summit London 2019: https://www.slideshare.net/BerndRuecker/aws-community-summit-london-2019-lost-in-transaction
• Serverless Conference London 2019: https://www.slideshare.net/BerndRuecker/serverless-london-2019-coordination-of-serverless-functions

Constantly under construction!

I use this demo for my talks. There is no gurantee on the stability of the code here - and it might be in a broken state any time.

Get started

AWS (Lambdas)

• Install Serverless framework and configure according to your AWS account
• Deploy lambdas
• Decide on the implementation approach you want to play around with:
  • Use BPMN on Camunda Cloud as managed service from Camunda and deploy a function triggering the workflow
  • Use AWS Step Functions as managed service from AWS

GCP (Google Functions)

• Install Serverless framework and configure according to your GCP account
• Deploy Google Functions
• Use Zeebe as managed service from Camunda Cloud and deploy your a function triggering the workflow
