We don't need more data centres. We need to make better use of the data centres we have today. Most businesses running in the cloud massively over provision their virtual machine capacity, and cloud providers are all too happy to sell it to them.

But this has created an pandemic of thousands of machines, sat whirring away in super-cooled data centres, doing absolutely nothing. Draining business' bank accounts, for nothing. Using up electricity, for nothing. Damaging the environment, for nothing.

This business model is beneficial for everyone: 1. Customers don't have to worry about server management, and are not at risk of overpaying for unused server capacity.

2. I am actively incentivised to use my infrastructure more efficiently. I have to ensure workloads are correctly and efficiently placed to fully make use of the physical resources, because I can't rely on customers picking up my tab for unused node capacity.

3. We don't need as many servers, not as many racks, not as many massive data centers. No need to build more, and more, and more. We have more than enough capacity today, we don't need to build more. We just need to use what we have better.
