What version of acs-engine?:

Version: v0.10.0
GitCommit: 7f3e25c2
GitTreeState: clean

Orchestrator and version (e.g. Kubernetes, DC/OS, Swarm)
Kubernetes, 1.7

Kubernetes already have support for multizone - e.g. deploying cluster over multiple regions in Azure, for high availability. How can that be done using ACS engine?
Currently, I create 2 different clusters (in eastus and westus region), with traffic manager to spread the traffic between the clusters. This is not ideal, but working. Ideally, this would be managed by kubernetes multizone feature - which will also be more efficient on resources.

I experienced same issue and I did exactly the same than you @omerlh

Kubernetes multizone feature is for single region zones and not multiregion. Azure currently is in preview for Availability Zones, which also utilize VM Scale Sets. Azure VM Scale Set support is slated for 1.10 . So support for K8 multizone will come sometime after that release. If you want cross region you would be looking at utilizing K8 Federation.

Note: #3453 adds zones support for agents. We will add zones support for masters in a different PR.
