Mission Focused Development

Designing for disconnected environments can seem like a niche concern — something only relevant for the extreme of specialty use-cases. But here’s the catch: The design principles that make software resilient in airgapped environments also make it more robust, secure, and reliable in connected ones. When you design for failure, restriction, and constraint — you build systems that are prepared for the reality of even the best - infrastructure, configuration and every detail between. ...

We’ve talked about personas. We’ve talked about environments. Now we need to talk about delivery. Because for all the advances in containerization, infrastructure as code, and supply chain security—getting software to run in disconnected or semi-connected environments is still far too hard. And the reasons why come down to friction. Disconnection Isn’t New—But Our Tooling Assumes It Is Disconnected systems have existed for decades: industrial control networks, classified enclaves, and remote field operations. What’s changed is the expectation that these environments should run modern, cloud-native applications—and the tooling that assumes a persistent cloud connection to do so. ...

When we talk about disconnected systems, we tend to imagine a binary state—something either connected or not. But that’s not how the real world works. Disconnection is not a fixed category. It’s a moving target shaped by mission needs, geography, infrastructure, policy, and even weather. The people who operate in those environments are just as varied as the systems they depend on. Who Are We Building For? Disconnected environments aren’t theoretical. They’re lived realities—places where people need to get real work done with constraints that most cloud-native assumptions ignore. ...

When you operate in an airgapped or semi-connected environment, technology decisions stop being expansive. It is no longer about which tools are shiny. It is about which ones will actually work when the internet is gone. Airgap constraints force sharper decisions at every layer of the stack. And the truth is, many of the most popular cloud native tools are not built with disconnection in mind. Let’s walk through what changes. ...

Airgapped systems are often treated as static, permanent, and immovable. They’re offline. They’re hardened. They’re not changing anytime soon. Until they do. More and more, we’re seeing environments that start as fully disconnected gradually gain controlled access to the outside world. A system that began life on a USB stick might later receive daily updates over a satellite link. A once fully isolated deployment might eventually support secure relay syncs or controlled egress through a policy gateway. ...
