I have a project to make a second datacenter that is located in a different geographic location a hot standby. Our goal is to make this second datacenter an immediate failover with minimal downtime. I know this can be easily accomplished with traffic directors, but we are looking for faster convergence. Our primary datacenter houses multiple web services. We have registered /22 and an AS from ARIN. I have an idea how I would set it up, but any ideas would be greatly appreciated.
I have this problem too.
