Four Scalability Obstacles on AWS

With Amazon Web Services’ announcement yesterday that CloudFront now supports POST, PUT, DELETE, OPTIONS, and PATCH requests, and a GIGAOM post, “Five features Amazon Web Services must fix”, I was prompted to complete an idea I had noted a couple of months back.

Amazon Steps Up CloudFront, Adds POST Requests – What It Means

Is Coding the new Fundamental Skill for Childhood Education?
