Clouds on Clouds: OpenStack and Kubernetes With Cloud-Barista - Seokho Son, ETRI

Wednesday August 12, 2026 14:15 - 14:45 KST

Orchid 2

Can you build OpenStack and Kubernetes clusters anywhere, across multiple clouds, and still understand how network connectivity works?

This session explores that question through a scenario using Cloud-Barista, an open-source multi-cloud orchestrator.

Instead of separate project overviews, this talk connects Cloud-Barista, OpenStack, and Kubernetes as infrastructure layers. Cloud-Barista provisions VMs on public clouds, then OpenStack is deployed on them. The OpenStack-based cloud is registered back into Cloud-Barista to create VMs and host a web service.

Will that service be reachable from Internet? If not, why? What makes it complex? These questions guide our explanation of network paths and reachability. We will apply the same lens to Kubernetes on multi-cloud VMs.

The focus is not just automation, but how connectivity works: public/private IPs, bastion access, cluster nodes, and how users reach workloads.

Beginners curious about these topics will gain practical insight into open-source infrastructure stacks.

This is not another cluster deployment talk. It is an experimental journey across open-source cloud layers, from multi-cloud IaaS to OpenStack and Kubernetes.
