One interesting challenge with Kubernetes is deploying workloads across several regions.

While you can technically have a cluster with several nodes located in different regions, this is generally regarded as something you should avoid due to the extra latency.

Another popular alternative is to deploy a cluster for each region and find a way to orchestrate them.

In this webinar, Daniele will demo live how to create, connect and operate three Kubernetes clusters in different regions.
