Cloud Versus Data Center Was Always the Wrong Fight
Updated: 6 days ago
Joaquin "Jack" Fagundo, writing from Parkland, FL, on why the real question was never cloud or data center, but where each workload belongs.
For about a decade, the industry argued about cloud versus the data center as if one would eventually swallow the other. It didn't happen. Public cloud grew enormously, and data center construction grew right alongside it, for the simple reason that the cloud runs in data centers too.
The cloud runs in data centers too.
So I've stopped asking leaders whether they're moving to the cloud. The more useful question is where each workload belongs, and the honest answer is almost always a mix.
Public cloud earns its place with speed and elasticity. New products, unpredictable demand and managed services all favor it. Colocation earns its place with control and connectivity, since predictable, dense or latency sensitive workloads often run more economically in a facility close to networks and partners. And owning the building still makes sense in specific cases: regulation, data sovereignty, or very large and very steady workloads.

AI pushes hard on power, cooling and GPU availability, and that's reshaping how these choices play out. A lot of organizations rent capacity in the cloud to get started, then move steady workloads to colocation once demand becomes predictable. Owning, leasing and renting compute each make sense at different points on that curve, which I explore in Follow the Megawatts.

Start with the business requirement, because speed to market, cost predictability, compliance and latency each point to a different answer. Map dependencies before you move anything; applications that talk to each other constantly should usually move together. Compare the full cost over several years, including data movement and the cost of the transition itself. And revisit placement regularly, because the right answer changes as usage, pricing and technology change.

The future of the data center isn't a choice between cloud and on premises. It's a portfolio, managed deliberately, with every workload sitting where it does the most good.
