In today's IT architectures, microservices and serverless functions play an increasingly important role. But how can you create meaningful, comprehensive, and connected business solutions if the individual components are decoupled and independent by design? This book provides a framework through examples and practical advice, and reveals how you can design complex processes in such an environment to deliver true business value.Systems that become more distributed, asynchronous, and reactive usually require state handling to deal with long-running interactions. Author Bernd Ruecker demonstrates how to use process automation technology to apply typical long-running patterns around resiliency, messaging, orchestration, or consistency without forcing your service implementation to become stateful itself.
