> Datacenters run at roughly 30% to 40% effective utilisation

I wonder what is stopping datacenters from passing this benefit to customers by launching better tuned plans. For example, t series EC2 instances on AWS.

Isn’t the fact that you just referenced it indicate that they do?

I feel like it’s probably just complexity.

Different workloads benefit from specific types of optimisations.

this is true of most actual clouds/neoclouds. oversubscription and intelligent placement of workloads is already something they do. I’ve known a few people at AWS who have offset unbelievable amounts of cost by optimizing placement.
