Hi Donovan Interesting, I'm wondering why you would use an EIP as the nature of Scalr DNS negates the need for such? It seems like an unnecessary step?
That said, load (and/or instance size) isn't really a concern for us at the design stage, we're just wondering if the Nginx LB is actually needed for a multiple instance LAMP farm as even though the Sclar wiki advises otherwise it's unclear how traffic would be distributed if not, unless, as Srini states, there may be some low-latency round robin DNS baked into the LAMP role?
