3. The Apps Perspective:
Services are the Infrastructure
• IaaS is really backwards
– Infrastructure is really an application component
• Resources are really API and QoS
– No idea “what” hardware is actually being used
• Cloud platform is the unifying framework
– The services interact to provide complete infrastructure
functionality regardless of underlying hardware
• Users, applications, operating systems, and data sets
“touch” only the services
– Hardware becomes peripheral and interchangable

4. Step 1 – Understand the
Application Workload
• Application workload characteristics
– Cloud abstractions
• Compute
• Network
• Storage
• Identity
– Deployment requirements for the application
• Reliability
• Load balance
• Geographic distribution (e.g. regulatory)

5. Step 2 – Understand
Application Governance
• Who owns the application workload?
– Different than who owns the code
• Must design a way for the cloud administrators to “see”
what the application is doing and to “talk” to the workload
owners
• Software ecosystem

6. Step 3 – Design the Physical
Deployment
• The cloud is a control plane
– Once the apps are running, the cloud is out of the “way”
• Imagine, after the apps are deployed, that the cloud
control plane vanishes for an instant
– Will the apps survive?
• VM capacities, network design, storage requirements

7. Step 4 – Design the Cloud
Deployment
• Private cloud is a scalable service venue
– Many cooperating service components requiring network,
storage, and compute
• High-availability and redundancy
• Traffic planning
• Memory requirements for cloud components

8. Step 5 – Test everything and
then test it again
• Figure or merit testing should be worst case
– Test failures
– Test upgrade
– Test failures during upgrade
– Test upgrade during failures
• Observe the testing results from the application
perspective
– What does the application experience if the cloud is
degraded?

9. Step 6 – Integrate cloud with
existing management policies
• The cloud is a new platform
– Not a set of independent tools
• Capacity planning
• HW budgeting
• Racking
• Identity management and security
• Coordination of scheduled down time
– Who gets called?

10. Step 7 – Lifecycle planning
• Plan to build incrementally
• Plan to hybrid incrementally
– Internal: Cloud and non-cloud components need to interact in
the data center
– External: Enterprise cloud and public clouds
• Plan to sunset incrementally

11. Eucalyptus
• Elastic Utility Computing Architecture Linking Your Programs
To Useful Systems
• Web services based implementation of elastic/utility/cloud
computing infrastructure
– Linux image hosting ala Amazon
• How do we know if it is a cloud?
– Try and emulate an existing cloud: Amazon AWS
• Functions as a software overlay
– Existing installation need not be altered
• Open Source
– Built from best-of-breed Open Source technologies for
eCommerce
