IT to focus on more important things while the basics are solved by users themselves. ✓ Easy scalability: One aspect of cloud is the ability to easily expand resource pools, but that requires under lying hardware that is easy to scale. At the same time, the individual workloads that users deploy should also be relatively easy to expand if the application calls for growth. ✓ Chargeback/showback: The public cloud makes it very clear how much you're spending, but many private envi ronments don't yet have this capability.

So many pixels and so much ink have been wasted on the idea that the public cloud is the end‐all, be‐all and only future of IT. That's simply not the case.

Over time, however, the operational costs associated with public cloud start to creep up and, eventually, you're staring a $100,000 monthly invoice in the face.
