Submariner enables direct networking between Pods and Services in different Kubernetes clusters, either on-premises or in the cloud.
As Kubernetes gains adoption, teams are finding they must deploy and manage multiple clusters to facilitate features like geo-redundancy, scale, and fault isolation for their applications. With Submariner, your applications and services can span multiple cloud providers, data centers, and regions.
Submariner is completely open source, and designed to be network plugin (CNI) agnostic.
