This topic is not mentioned much, but it can provide a solution when services in a region get hammered and you want fine-grained control over routing.
Go to this URL for info: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html
Also, I think it would help to update this lecture to mention that geo proximity routing is setup using traffic flow in Route 53. I understand walking through how it’s setup might not translate well to a video. In that case, please at least show a screenshot of Route 53 and show where this is setup.
Thanks for the suggestion lecube. I’ll take it under advisement.
