From Camunda

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. I co-authored "Real-Life BPMN,", 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 architect

Lost in transaction? Strategies to deal with (in-)consistency in modern architectures.


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. Welcome to a world without ACID transactions which leaves you in charge of dealing with difficult problems yourself e.g. eventual consistency, distributed transactions, compensation or message delivery semantics like "exactly-once". In this talk, I’ll briefly describe why this will become the new normal and which challenges arise for us as developers. I will discuss strategies to deal with it and present real-life experiences, recipes, patterns and frameworks. Expect fun little live hacking sessions with Open Source components like Spring, Hystrix, Kafka and Camunda.
