The importance of APIs is increasing. Usually, API projects do not start on a green field. Often there's an existing, mostly monolithic application landscape, which needs to be embedded and integrated with new applications implemented in a Cloud-native fashion on new technologies like Kubernetes. The question is: Which principles must be considered to build a future-oriented, flexible API management platform? It is potentially not enough to simply work with a central, monolithic API gateway solutions. But, what requirements are placed on a modern API management platform? This session will give an introduction on how modern API architectures should be build, considering concepts like Microgateways, Ingress and Servicemesh.
