Prove. It.
And not in a "enterprise who needs to build entire datacenters" kind of way. For the 99.9995% of businesses out there who don't build datacenters. For whom renting 1-4 racks at a colo is just fine.
Prove azure's cheaper. For real world workloads, not ones designed from scratch for the cloud. Prove it, prove it, prove it.
Stop your assertions, drop the anonymous coward and man the fuck up with some actual evidence.
There are only 17,000 "enterprises" in this world. There are over one billion businesses. Prove your assertion in the context of the majority.
Proof. Not assertions. Proof.
