3.9.1. Efficiency Principle - Design for cloud-scale efficiencies:
When realizing cloud characteristics such as elasticity, self-service access, and flexible sourcing,
the cloud design is strictly oriented to high cloud scale efficiencies and short time-to-delivery/time-
to-change.To implement a cloud following this principle with that high level of efficiency
and flexibility,a very high degree of standardization(i.e. minimal variety in the data center with
respect to numbers of server, storage, network technologies, operating systems & versions,
middleware products, applications, etc.)is required to enable high degrees of automation.
