using them to respond to storage events on s3 or database events or auth events is super easy and powerful. OpenConnect, the ability to deploy the CDN directly into the internal network of these ISPs served multiple purposes--not the least of which was to expose the fact that they were holding Netflix for ransom.

In this configuration, the AMI and boot is paravirt (PV), the kernel is making hypercalls instead of privileged instructions, and the system is using paravirt network and storage drivers. It's all a bit confusing, and I wrote about this in 2014: [Xen Modes]. AWS called this [enhanced networking]. The first was c3.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two. Modern network performance and availability.
