Designing good applications has become more demanding than ever: Extremely flexible, very high availability, scaling up and down on demand, rising user demands, sustainability, APIs as first class citizens while being secure like a fortress at the same time, and so on.

But that is not possible anymore. In this session, we will take a look at how our application design demands have changed, what you need to take into account to design good applications and how to tackle the challenges best. Let us get ready for the architectural work of the coming years and learn how to square the circle!
