Orchestration of microservices

Microservices, DDD, distributed systems, serverless. All trends decompose to the max, which moves the complexity to the collaboration of these pieces. I want to tell some war stories around that in this talk and give people some guidance.

Abstract

Microservices, DDD, distributed systems, serverless. All trends decompose to the max, which moves the complexity to the collaboration of these pieces. I want to tell some war stories around that in this talk and give people some guidance. How can you implement complex end-to-end use cases (e.g. a customer order) when you have a bunch of nicely decoupled (micro-)services (e.g. checkout, payment & shipping)? How do the services collaborate? Synchronous or asynchronous? Choreographed using event-chains? Orchestration using frameworks like Netflix Conductor? In this talk, I discuss different alternatives and show how to handle long running processes and requirements around state, error handling, timeouts, distributed transactions or compensation. I discuss how you can ensure visibility and provide status and error monitoring. Expect live hacking leveraging lightweight open source frameworks like Zeebe.io. I will share our experiences from real-life projects.
