The open source Kubernetes startup Rancher makes public its easy way to deploy containerized applications to multiple clusters. It’s almost as easy as point and click.
Running apps on multiple clusters is nothing new.
High-availability requirements often necessitate cross cluster deployments, as do edge deployments.
Traditionally, multiclustering has been done by pulling nodes from various availability zones into a single cluster, with results that are less than optimal because if the cluster fails, the app becomes unavailable system-wide.
You are deploying clusters and using this platform to update your app in any cluster running on any infrastructure of your choice.”
Multiple cluster support is currently available in Rancher 2.2 Preview 2 and the feature will be included in the official release of Rancher 2.2 later this year
