Over the past two decades, the migration of workloads to the cloud has been dominating the landscape and is now evolving towards solutions that encompass more than just a single cloud instance. Organizations are increasingly more interested in defining valid multi-cloud strategies, and with that the need for robust and secure architectures arises. This elevates the intrinsic challenges that come with cloud infrastructures to a whole new level and introduces new challenges tied to the clusters' distribution on different cloud providers like automatic service discovery in different networks, consistent identity and access management throughout the entire architecture, secure channels for communication across clusters and a way of monitoring/logging the whole workload's interactions.
