Abstract
The state of the art in designing scalable services relies on microservices with Kubernetes being the de facto platform for deploying them. While the Cloud Native Computing Foundation has standardized and improved several features in Kubernetes, one of the challenges remaining is that using multiple clouds simultaneously and dynamically, for example, in a hybrid-cloud setting, is not possible. We address this crucial challenge by integrating the multi-cloud computing solution Federated Kubernetes with the emerging multi-cloud networking tool Network Service Mesh (NSM). This is the first solution for enabling Kubernetes-based multi-cloud workloads with seamless connectivity meeting the requirements for multi-cloud services and the telco industry in 5G and beyond systems.
