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
“My UI will be easier to use” customers SLAs”
“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 “I let my customers span
snapshot machine images” multiple clouds”
Example of the Future: Open Source Cloud Framework

4. Good Parents 170+ companies

5. Typical Provisioning Workflow
-Paperwork
-Storage
-Systems
-Network
-Security
-Licensing
-Scheduling
-Reporting
-Billing
-Repeat
-Efficiency?

6. Demo Components Nerd Warning
• OpenStack - Orchestration BPDUGuard good
• OpenvSwitch - Network Virtualization
• Kernel Virtualization Module (KVM) – Hypervisor
• Bare Metal x86 Server Dell r910 & r720
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 spin up.
• 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.

• It should be the next x86 market. Have we admitted that yet?
• The value in abstraction is proven.

10. 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)
