Some buzzwords have stronger underlying value than others. Hybrid Cloud is very critical for orgs that want to migrate or partly use cloud resources, say for moving capital expense to operating expense or for burst uses, but don’t want two different tool chains. IBM/RH’s offer is more flexible then Azure Stack or pieces of Google like Anthos, but the flexibility comes at a higher cost.

In any case, is buzzword but not the same variant of buzz as blockchain.
