# ZonelShiftLab
Deploy VPC, Subnet, Ec2, NLB for testing Zonal Shift
## Description
When zonel shift is initiated, the paused AZ will stop responding after 1-2 minutes
After cancelling a zonal shift, wait for DNS TTL to expire and the resumed AZ should start responding.
To initiate / cancel zonal shift:
```bash
aws arc-zonal-shift start-zonal-shift \
--resource-identifier <RESOURCE_ARN> \
--away-from <AZ_ID> \
--expires-in <DURATION eg 30m> \
--comment AzFailoverTest
aws arc-zonal-shift cancel-zonal-shift --zonal-shift-id <SHIFT_ID>
```
