Windows host zone redundancy

What this Scenario does

This Scenario drops network traffic between your Windows hosts in one availability zone and the rest of your infrastructure, simulating a complete zone outage. This forces your load balancers and routing mechanisms to redirect traffic to Windows hosts in the remaining zones.

‍

Why run this Scenario?

• Demonstrate that your Windows infrastructure is truly zone-redundant, not just deployed across multiple zones.
• Verify that load balancers detect the zone outage and redirect traffic to healthy Windows hosts in other zones.
• Test whether your secondary zones have enough Windows host capacity to handle the traffic surge from the failed zone.
• Ensure that Windows failover clustering and traffic routing return to normal when the zone recovers.

‍

Expected outcome

When a zone fails, Windows hosts in secondary zones automatically absorb the traffic with no interruption in service.
