The Cloud Is Software — But What Kind of Software?

Everyone talks about the cloud as if it were some magical place. But peel back the layers, and you'll find something very real — a stack of software. Not just any software, though. The cloud is a stack of scheduling software disguised as a platform.

At its core, the cloud is a resource scheduling machine — an intricate, layered software system designed to do one thing brilliantly: allocate compute, memory, storage, and bandwidth across physical hardware in the most efficient way possible. Think air traffic control meets financial optimization — except instead of landing planes, it’s packing workloads into virtual machines, containers, and serverless runtimes.

It’s beautifully engineered. Every abstraction you see — virtual machines, Kubernetes clusters, serverless functions — exists to optimize usage of the underlying data centre hardware. The result? Maximum utilization, minimum idle time, and very little waste.

But here’s the kicker: who benefits from all this efficiency?

Surely, it’s the customer, right? The company making the smart move to the cloud, hoping for reduced costs and greater flexibility?

Well… kind of.

Yes, moving to the cloud often has a positive ROI — particularly if you’re moving away from on-premise servers that sit idle 80% of the time. But let’s not kid ourselves: the cloud is even more profitable for the cloud providers. We're talking 50%+ gross margins in some cases. Once you're in, there's often no way out. The platform is sticky, the ecosystem is vast, and every service you consume is another margin enhancer — for them.

And if you just "lift and shift" your old infrastructure to the cloud without rethinking how you use it? You’re not saving. You’re burning.

At the very least, take FinOps seriously.

FinOps (short for Cloud Financial Operations) is a modern practice that helps organizations control their cloud spend and maximize business value from every euro or dollar spent. It’s about aligning engineering, finance, and business teams around one shared goal: efficient cloud usage.

The FinOps Foundation framework introduces three core phases:

1. Inform – Gain visibility and allocate costs accurately.
2. Optimize– Rightsize, schedule, and eliminate waste.
3. Operate – Establish processes, accountability, and continual improvement.

It’s not about cost-cutting for the sake of it. It’s about spending wisely, understanding your usage patterns, and adapting your architecture to make every bit of cloud count.

Cloud is powerful, flexible, and often the right move — but only if you run it on your terms.
