The Disconnected Edge: How We Solved In-Flight Data Sync at 35,000 Feet

When most engineers think about rolling out a modern streaming or web application, they visualize a standard cloud-native environment: a global CDN, elastic load balancers, and a continuous pipeline pushing updates to infinite resources.

But what happens when your deployment target is an isolated, battery-powered hardware device flying inside a metal tube at 35,000 feet?

At AirFi, operating a next-generation In-Flight Entertainment (IFE) platform forced us to completely rethink modern web architecture. When you lack a persistent, high-bandwidth connection to AWS, the cloud can no longer be your source of immediate truth. Instead, you are forced to conquer the ultimate disconnected edge problem.

Here is how we designed a hybrid, localized infrastructure to keep our systems updated without consuming precious in-flight bandwidth.
