A company’s core business processes nearly always span more than one microservice. In an e-commerce company, for example, a “customer order” might involve different services for payments, inventory, shipping and more. But how do these services play together to fulfill the customer’s desire?
Implementing long-running, asynchronous, and complex collaborations between distributed microservices is challenging. How can we ensure visibility of cross-microservice flows and provide status and error monitoring? How do we guarantee that overall flows always complete, even if single services fail? Or how do we recognize stuck flows so that we can fix them?
In this webinar, Bernd will explain how workflow automation supports the orchestration of microservices, to make sure business processes are always carried out - even in case of failure -
providing monitoring and visibility into the overall progress and status.
He will reveal how to do all of this without introducing monolithic workflows that clash with microservices principles. You will also learn how to balance orchestration (using a workflow engine) with choreography (using events). Still believe that choreography is more loosely coupled and thus the modern way to go? You definitely need to listen in…

Today, every company is becoming a software
company and developers are at the center of
digital transformation; they drive business
processes and functions across organizations
from customer service and HR to marketing and
IT. And the choices these developers make will
increasingly determine value creation and
growth across every industry.

22. The danger is that it's very easy to make
nicely decoupled systems with event
notification, without realizing that you're
losing sight of that larger-scale flow, and
thus set yourself up for trouble in future
years.
