The growth of the Internet knows no rest, and brings with it the necessity to deliver services at unprecedented orders of magnitude. The cloud has become the foundation upon which services can be delivered and managed at scale, along with engineering applications to be cloud-native. In this context, Kubernetes has been the driving force behind the successful management, deployment and delivery of large-scale services. With Kubernetes, computing nodes are brought together into clusters, where organizations have full visibility over the overall resources at their disposal, for an effective utilization of the deployed infrastructure. Moreover, companies may need to control multiple clusters to ensure their presence in multiple regions, increase availability, scale better in terms of maintenance, and may rely on different cloud providers for cost management or vendor lock-in avoidance.
