Definitely not true. Cross AZ is incredibly high compared to within the same AZ. We run a bespoke multi-master database setup that must be colocated to the same AZ due to unacceptable latencies when run spread across 3 AZ's. A few ms difference |

yes, while in my opinion most services won't care about the distinction between cross-az/same-az (you're definitely not most services :) ), you can definitely tell the difference between
* in the same region vs not
* in the same az vs not
* in the same placement group or not
which shouldn't be surprising. you should get a latency benefit from increased physical proximity!
