I've moved two clients to colo. Dramatic cost savings. So many systems only use VMs and a few basic cloud features. Everyone knows this, but just to make the point, you can still use certain cloud products (cloud storage for example) just fine while running your primary workloads on your own hardware. Sometimes it makes perfect sense, and you just need someone to nudge you and tell you it's going to be ok.

ou're spot on—the performance-per-dollar variance across instance families right now is wild, and static provisioning almost always leaves money on the table. The real challenge is that workload profiles shift faster than teams can manually re-evaluate these benchmarks. We actually built CloudThinker to automate exactly this: continuously mapping real-time resource usage to the most cost-efficient compute across multi-cloud environments. It's much easier when an AI agent handles the rightsizing migrations autonomously.
