SKUPPER

Once a Skupper network is formed across Kubernetes namespaces, any of the services in those namespaces can be exposed (through annotation) to the Skupper network. When a service is exposed, Skupper creates proxy endpoints to make that service available on each namespace in the Skupper network... Multicluster communication for Kubernetes. Skupper is a layer 7 service interconnect. It enables secure communication across Kubernetes clusters with no VPNs or special firewall rules... Skupper provides a solution to this challenge with a Virtual Application Network that simply and securely connects applications running in different network locations.
