Tom Lyon showed us, at Cloud Field Day, that history has a funny way of repeating itself, especially when we think we’ve invented something entirely new. We talk about the cloud like it’s a modern miracle, but a look at history shows we’re just replaying a script from nearly a century ago. The cloud isn’t a destination or a specific technology. It’s a business model. It’s the latest version of the service bureau, a concept dating back to IBM in the 1930s. Back then, if you needed to process data, you didn’t buy a room-sized mechanical tabulator. You took your punch cards to an IBM Service Bureau. You paid to use their machines and their expertise. You outsourced the complexity. Sound familiar? It should. It’s exactly what happens when you spin up an instance on AWS today.

The cycle moved to the “computer utilities” of the 1960s. Visionaries predicted computing power would be delivered like water or electricity. You’d plug into a grid, use what you needed, and get a bill. The technology was different, time-sharing and primitive networking, but the economic impulse was identical. We wanted someone else to worry about the cooling, the power, and the maintenance.

We see this “rise and fall” repeatedly. A new capability emerges, we centralize everything into hubs, and then costs creep up. Latency becomes an issue, regulations change, and then suddenly everyone wants to pull their data back home. We’ve been swinging this pendulum for decades. In the late 90s, Application Service Providers promised the world, but the infrastructure wasn’t ready. The dream outpaced the reality of the pipes in the ground.

Now, we’re in a massive upswing driven by AI, but the cracks are showing. When companies talk about “sovereign clouds,” they’re reacting to the same pressures that drove people away from old service bureaus. They want control. They’re realizing the cloud is just someone else’s computer, and sometimes that computer is too expensive or too far away.

We aren’t entering a world without the cloud. The service bureaus didn’t vanish; they evolved. We’re just moving past the phase where we thought every legacy app or modern AI feature belonged in the public cloud. We’re thinking more critically; it’s not the end of the cloud. It’s just the end of our naivety about it.
