David Rubinstein’s post “Industry Watch: Be resilient as you PaaS” makes a very good point about underutilized hardware in IT data-centers.
Millions of enterprise workloads remain in data centers, where servers are 30% to 40% underutilized, and that’s if they’re virtualized. If not, they’re only using 5% to 7% of capacity.
The reason for this?
Take, for example, servers that are spun up for a project two years ago that were never decommissioned, just sitting there, waiting for a new workload that will never come. And, because the costs of blades and racks went down, cheap hardware has led to a kind of data center sprawl.
