  2. 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.

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

  6. Demo Components • OpenStack - Orchestration • OpenvSwitch - Network Virtualization • Kernel Virtualization Module (KVM) – Hypervisor • Bare Metal x86 Server Dell r910 & r720 Nerd Warning BPDUGuard good • 10 minute demo the following • As Provider • Provision new customer/tenant and UIDs. • Modify policy for quotas including usage in storage, VCPU, memory, images OS and capacity, network addressing based on customer need. • As Customer • Login as user and self-provision SSL keys and apply 5-tuple security policy to each host we spinup. • Launch Windows 2008 R2 and Linux hosts with varying levels of memory, CPU and ephemeral storage. • Assign networks to these hosts based on purposing. • As Provider and Customer • Review usage data for capacity planning, SLA fulfillment, usage analytics and billing.

Have we admitted that yet? • The value in abstraction is proven.

  10. Change is Bad • We are operating far to close to the hardware. • 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. • Forwarding: Networking gear with flow tables and firmware. • State: Bag of protocols destruction. • Management: Orchestration, CMDB etc. Join the rest of the data center (and world)
