High Availability, same site using sperate NodeBalancers
I would like to use NodeBalancers on multiple data centers, so I have 3 NodeBalancers on 3 different locations, when each NodeBalancer got 3 nodes.
I want 100% Up time. What would be the best way to make that I'd have the same site running on 3 different NodeBalancers? UltraDNS? Round-robin DNS? Any other suggest?
