Then haproxy/nginx is your single point of failure and you need to put a load balancer in front. Back to square one.

The usual way to have failover on load balancers is VRRP [1] and that doesn't work well in the cloud.

[1] Also known as HSRP, VRRP, keepalived, CARP

Decent VPS/Rented Dedi providers, and surely all Colo providers can provide IP failover.

Edit: my point is, if a "cloud" load balancer can't provide the features you want (e.g. TLS SNI) and the "cloud" VM's can't provide the features you need to run your own LB (e.g. IP failover) maybe this is an opportunity to learn that the "cloud" isn't some golden goose shitting out golden eggs.
