Join us for a hands-on session on using Lambda@Edge and Amazon CloudFront to deliver high-performance and personalized experience to your Internet users across the globe. You will walk away with a working setup of combining Amazon S3, Amazon DynamoDB, and Amazon CloudFront with Lambda@Edge to build websites which are simultaneously hosted across AWS locations across the world. We will explore architecture, configuration, and dev-ops with real examples of how AWS customers are using Lambda@Edge for their websites.

Aliens Are Here!

Meet the Un-Canny
Aliens have arrived, and established their bases over
major metropolitan areas across Earth. After several
failed attempts of peace dialogue, we realized—we just
can’t communicate.
Humans and Aliens do not share a common language!
This is our last attempt, and world leaders are looking
up to you to deliver a social platform—high
performance, highly available, and Serverless—for
Humans and Aliens to communicate through—Alien
Cards!
Alien Cards (Kindergarten cards, but for Aliens) might
be the last chance for humanity… and it rests on your
shoulders!
