Lost in transaction? Strategies to deal with (in-)consistency in distributed systems

You probably work on a distributed system. Even if you don’t yet face a serverless microservice architecture using fancy NoSQL databases, you might simply call some remote services via REST or SOAP. This leaves you in charge of dealing with consistency yourself.

ACID transactions are only available locally within components and protocols like two-phase commit don’t scale. Many projects either risk adventurous inconsistencies or write a lot of code for consistency management in the application layer.

In this talk Bernd discusses these problems and goes over possible solutions, including the Saga-Pattern. Bernd will discuss recipes, patterns and frameworks that allow us to manage the right level of consistency but concentrate on the business logic. Expect fun little live hacking sessions with open source components, but also real-life stories.

About Bernd

Throughout my 15+ years in software development, I have helped automating highly scalable core workflows at global companies including T-Mobile, Lufthansa and Zalando. I have contributed to various open source workflow engines. I am co-founder and developer advocate of Camunda, an open source software company reinventing workflow automation. I co-authored “Real-Life BPMN,” a popular book about workflow modeling and automation. I regularly speak at conferences and write for various magazines. I am currently focused on new workflow automation paradigms that fit into modern architectures around distributed systems, microservices, domain-driven design, event-driven architecture and reactive systems.
