Create an HA pair using only an Elastic IP
This Powershell script is designed to run on two machines, and to transfer the elastic IP to the running instance should one fail. This script is loosely based on https://aws.amazon.com/articles/2127188135977316 but has several key differences:
- This provides HA for the public elastic IP without need for an elastic load balancer
- This script runs in windows as a scheduled task at startup under the SYSTEM account.
- This script logs errors to the event viewer
