How Amazon SNS bills you
The pricing model is per million ($0.50/m push). Pub/sub messaging primitive with mobile push at hyperscale and effectively free volume, but no engagement layer. Best suited to: hyperscale pub/sub + mobile push.
What to watch for on the bill
- 64KB-chunk billing means a 256KB message counts as four requests, inflating costs unexpectedly
