This is kind of... fluffy for an HN post. It makes no mention of distributing your application between availability zones as a first step, swats away at the issues involved in any of the suggestions, then ends with “just configure what you need to configure for RDS and S3 replication and restore the rest by hand from backup.”

Author here - totally fair. It is pretty high level. Distributing across AZs is mentioned in the fact it only accounts for HA, not DR.

The intent of this post was mainly to counter the arguments I was seeing online that dismissed multi-region setups as a way to guard against AWS outages because "it's too hard." I merely wanted to point out there is a way to do it without it being super complicated, or super expensive. There seems to be a trend to build super fancy architectures and as a whole, many people have neglected the simple "good enough" options.

It’s especially unnecessary when AWS has considerably more information available with the right questions to ask:
