In this talk – which I proposed for KanDDDinsky 2018 and with which I want to experiment together with you! – I want to show how interrelated policies allow us to design „long-running services“. Such services deliver valuable results for their clients by implementing whole business processes. I will illustrate how the resulting APIs of „long-running services“ in my mind help to protect context boundaries. From an architectural point of view I will explain and leverage the idea of CQRS (Command Query Responsibility Segregation – as presented by Gottfried Szing in February) and discuss how the necessity to implement „process managers“ nicely fits into this pattern.
