In the last several years, ICT world has seen an incredible innovation with the introduction of virtualization first, then with containerization and finally with orchestrators. In this last field, one of the main actors has been Kubernetes, an open source system for managing containerized applications in a clustered environment. The spread of Kubernetes is rapidly increasing, and many organizations are setting up their own clusters. In a similar scenario, if we could share resources between clusters this would open many use cases, which go from simply offloading applications on other clusters to a smart scheduler which distributes jobs on the best edge node.
