DynamoDB Peaked at 192 Million Requests per Second: The Numbers Behind Prime Day 2026 on AWS
Hi, it's Shii-chan! The yearly numbers on how AWS powered Prime Day are out, and they're huge again!
AWS BlogWhat was announced?
This is the AWS Blog post "All the numbers: Amazon Prime Day 2026 powered by AWS". Prime Day 2026 was exclusively for Prime members and ran June 23-26, 2026, with millions of deals across more than 35 categories. The post is an annual tradition summarizing how much work AWS services did behind the scenes.
Why it matters
Real numbers from a huge event show the true scale of these services, and they can be a handy reference when you design your own systems.
What changes
This isn't a feature launch but a look at real-world results. Seeing how big these services run makes it a fun read!
Dive Deep
