Thanks for the info.

I'm interested in having my own IPs mainly so that I can move servers wherever I want and take the IPs with me. CNAMEs can only go so far when it comes to moving things around without interruption.

It's only a small personal operation though - and I am aware that limitations with hosting providers and ISPs may prevent me from being able to point my own IPs to them.

If you're not satisfied with the low-TTL/round-robin strategy, you would need to build out some private infrastructure to perform routing failover.

A tunnel with private routers between two cloud providers would allow you to advertise private host routes (/32) inside your network while NAT-ing appropriately to the outside. This achieves manual failover (or fast migration), but it can be expanded for dynamic failover, as well.

Let me know if you'd like me to elaborate the above solution. Otherwise, good luck with whatever solution you choose.
