When he saw a demonstration of the
telephone in 1880, a U.S Mayor declared: “One
day every town in America will have a
telephone!”

Cloud Myths
1 There is no “private” cloud, datacenters are a thing of the past.
Data Point: Mainframes are not dead.
Cloud Myths
2 All existing applications will be re-architected for the cloud.
Data Point: Service oriented architectures did not rule the world for years
Cloud Myths
3 You can drag-and-drop applications between “private” and public clouds.
Data Point: We have not solved for the speed-of-light.
Cloud Myths
4 Amazon will be the only cloud provider and they have already won.
Data Point: Windows did not destroy Unix.
There will be multiple options with various pros/cons.
Cloud Myths
5 You have to re-architect your applications to move to the cloud.
Data Point: Companies are already running thousands of migrated apps to the cloud today.

Hybrid Cloud Architecture
Considerations for Enterprise Cloud Adoption
• Application Workloads• Architectural Complexity• Lifecycle Phase• Agility and Innovation • Visibility and Control
Which applications should go?
Existing Applications Greenfield Applications
Consider Cloud Architectures• Compute can and will
disappear• Must be stateless• Automated infrastructure
provisioning• Constrained CPU/RAM
options• Limited networking
capabilities (today)
Move without re-architecting• Compute is always available• Stateful or Stateless• Manual infrastructure
provisioning • Various CPU/RAM needs• May have specific networking
needs (e.g. Layer 2)
Architecture & language dictate best destination
Simple Architectures Complex Architectures
• N-tier apps• Several service dependencies
• Consider IaaS offerings• Greater flexibility• Operating System access
• Consider moving individual components and keeping some components on-premise.
• Consider extending with cloud based application services
• 3-tier• No dependencies
• Consider PaaS offerings• Limited flexibility• Obscured the
infrastructure• Designed for scale out
• Existing apps will most likely still require some level of re-work
Lifecycle Phase Matters
Agile Application Development
Product Operation
• Infrequent Provisioning
• Lower Change Rate
• Heavy Security, Data Privacy, and Availability demands
• Monitoring Mandatory
• Predictable workloads
• Rapid Provisioning
• Frequent Changes
• Fewer Security & Data Privacy Issues
• Integration with ALM tools needed for Continuous Integration
• Unpredictable workloads
IT can be the hero vs. the gatekeeper
End User Groups IT
• Deliver greater agility
• With visibility and control
• Lower costs
• Desires greater agility
• Self Service Infrastructure
• Access to new technologies

Case Studies
Software Development and QA
Requirements:• Complex software stacks requiring tiered
networking and clustering• Self service for App dev team• Environments support hands-on global
user acceptance testing and training• Constrained IT staff resources for
infrastructure management
Value Delivered: • Rapid provisioning of VDC templates• Full VDC snapshots for defect capture• Parallel Development and QA team work• Project level reporting
Software Development and QA
Challenges:• Needed ad-hoc cloud capacity to test and
deliver data center applications• Distributed IT users; 10s of users in
England and US. 2 different vendors • Base dev/test configurations contained 180
VMs; ability to refresh at will• Multi-platform support, Windows / Java
applications, BMC, HP applications• Hybrid model to connect back to datacenter
Value Delivered: • Cost savings in up front capital expense • Reduced provisioning time down 20 days to less than one hour• Deferred hiring 2 FTE for IT management
Case Studies
Quantum Dawn 2 was a cyber security exercise to test incident to a wall-street-wide cyber attack.
http://nuari.org/
In July 2013, the Norwich University Applied Research Institutes (NUARI) teamed up with exchanges, broker-dealers, the SEC, Department of Homeland Security, and utility companies in US equity markets to simulate a range of cyber attacks that could potentially impact not only individual market participants, but also the market as a whole. 500 individuals took part in the simulation.
Closing ThoughtsWhy are you doing it?1
2 Define the application characteristics you want to start with.
3 Evaluate support for current tools & processes.
4 Test drive the self-service interface to assess learning curve.
5 Evaluate your ability to manage/control resource consumption.
Consider scalability both of infrastructure as well as terms. 6
