A main theme in modern architectures is around fine-grained, isolated, reactive components, that are managed by autonomous teams (think microservices). This is considered key to decoupling, which, in turn, leads to business agility. Unfortunately, this often goes wrong and people end up with more tightly coupled systems, that are hard to understand and change - the opposite of agility. In this talk, I will explore why this happens and provide my view on how process orchestration can improve the situation without harming any good architecture.

Target Audience: Architects, Lead Engineers, IT Decision Makers
Prerequisites: Basic knowledge in Microservice architecture
Level: Basic

Extended Abstract:
I will walk you through the challenges around event-driven systems and microservices, talking about orchestration and choreography, also showing you how to balance both architectural approaches.
I will further discuss the importance of looking at end-to-end processes before going into local automations, as local optimizations can actually harm the global result.
I will further compare different approaches to automate end-to-end processes, from batches over streaming to workflow engines. You will understand the impact on agility and get guidance on decision criteria, backed by examples collected in various real-life projects.
I will sketch what influence those architecture decisions have on the governance and enterprise architecture of organizations.
