In this deployment scenario, there is a single Rancher Manager instance managing Kubernetes clusters across the globe. The Rancher Manager would be run on a high-availability Kubernetes cluster, and there would be impact due to latencies.
In this deployment scenario, there is a single Rancher instance managing Kubernetes clusters across the globe. The Rancher instance would be run on a high-availability Kubernetes cluster, and there would be impact due to latencies.
### Pros
* Single control plane interface to view/see all regions and environments.
* Kubernetes does not require Rancher to operate and can tolerate losing connectivity to the Rancher Manager instance.
* Kubernetes does not require Rancher to operate and can tolerate losing connectivity to the Rancher instance.
### Cons
* Subject to network latencies.
* If the Rancher Manager instance goes down, global provisioning of new services is unavailable until it is restored. However, each Kubernetes cluster can continue to be managed individually.

## Regional Strategy

In the regional deployment model a Rancher Manager instance is deployed in close proximity to the downstream Kubernetes clusters.
In the regional deployment model a Rancher instance is deployed in close proximity to the downstream Kubernetes clusters.
### Pros
* Rancher functionality in regions stay operational if a Rancher Manager in another region goes down.
* Network latency between Rancher Manager and downstream clusters is greatly reduced, improving the performance of functionality in Rancher.
* Upgrades of Rancher Manager can be done independently per region.
