I’ve been deploying 3xAZs in 3xRegions for a while now (years). The backing store being regional s3 buckets (keeping data in the local compliance region) and DDB with replication (opaque indexing and global data) and Lambda or Sfn for compute. So far data transfer hasn’t risen to the level of even tertiary concern (at scale). Perhaps because I don’t have video, docker or “AI” in play?

I’m guessing either you don’t have much data or your infra is already so absurd that, yeah, the transfer costs are irrelevant by comparison.

[mlhpdx]

Not using VPCs (no need without instances/containers/RDS) mean most of the “absurd” costs go away. It’s cheap by any standard.

[hipadev23]

VPCs don’t cost anything.

[mlhpdx]

Sorry, that was indeed nonspecific, you’re right. The add-on features for VPCs are commingled with the concept for me since they almost always go hand in hand. Internet gateways, transit gateways, EIPs, service endpoints, etc., and their fixed costs. Yuck.

[icedchai]

All that stuff definitely adds up. I'm familiar with some low traffic projects with high "security" requirements that have so much overhead due to those sorts of adds-on. All the overhead winds up costing more than the actual compute + bandwidth running the site.
