One of the requirements of traditional hybrid cloud is seamless connectivity between multiple clouds. That has historically been difficult, so modern hybrid cloud has moved away from that, focusing instead on building applications that can move seamlessly between environments. However, there are still many cases where connectivity between clouds is desirable, and setting up individual connectivity between applications or services hosted in different clouds quickly becomes unmanageable.

Submariner is an upstream project which provides seamless connectivity between Kubernetes clusters. Once it's deployed, applications in one cluster can transparently access services exported from other clusters, even in clusters with conflicting network setups (overlapping subnets in particular).

This session will provide an overview of what Submariner provides for end users, and a brief description of how it works. It will include a detailed demo of Submariner deployment on multiple clusters, and service deployment across clusters, including round-robin access to services available in multiple clusters.

Attendees are expected to have some familiarity with cloud concepts and Kubernetes terminology such as services, nodes and pods. They will discover how to deploy and use Submariner to connect Kubernetes clusters.
