That's true, when only dealing with 1 server, you technically double the cost by adding a second server. My original comment was about "popular sites/services", that should be able to tolerate the costs and are most likely dealing with multiple servers.

For a single server deployment you can still reduce your downtime (with minimal costs) by having the ASG redeploy into another AZ on a failed health check.
