Network is the Substrate Cloud computing refers to the delivery of computing and storage capacity as a service to a heterogeneous community of end-recipients. The name comes from the use of clouds as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts services with a user's data, software and computation over a network. Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services over networks.

“I need a different VM placement policy” “I’ll build in a way to share revenue with my customer’s” “I want to report on my customers SLAs” “My UI will be easier to use” “I have a much better way to snapshot machine images” “I let my customers span multiple clouds” OpenStack Example of the Future: Open Source Cloud Framework

Change is Bad We are operating far to close to the hardware. o Do systems administrators configure their services in x86 Bios? Well, we do. Generic components decomposed into resources to consume anywhere, anytime. Abstraction of Forwarding, State and Management. o Forwarding: Networking gear with flow tables and firmware. o State: Bag of protocols destruction. o Management: Orchestration, CMDB etc. Join the rest of the data center (and world)
