Extend clusters across multiple environments
Talos Linux, the operating system designed for Kubernetes, includes KubeSpan. KubeSpan securely and transparently establishes full encryption between all members of a cluster – even if they are running on completely different networks and behind firewalls. All cluster members will find each other, and automatically update reachability information.
KubeSpan operates outside of Kubernetes. It works with any CNI, and even if Kubernetes is broken. KubeSpan is a highly-reliable connectivity system with many layers of privacy and security built in, from the ground up. And to make your cluster KubeSpan enabled is a single configuration option.
