2. Overview Cloud opportunities and challenges
Spectrum from on-premises to cloud
Value for different points on spectrum
Framework for targeting apps to cloud
Questions to ask
Technology, tools, and approaches
Future-oriented presentation

3. What is Cloud Computing
Style of computing with dynamically scalable and virtualized resources provided as a service through the network
Cloud Application Model
Scale-out
Service-oriented
Model-driven
Applicable to traditional systems and the cloud

4. Opportunities and Challenges
Greater agility
Lower cost: CAPEX, OPEX
Targeting applications to the cloud
How to leverage on-premises, public, private and dedicated clouds
Privacy of data
Connectivity
Latency/performance considerations

5. Spectrum Extending Into the Cloud
Traditional Datacenter
Well-known, stable and secure
Utilization <15%
Virtualized Datacenter
Utilization Increases to >50%
Management Costs Decrease

10. The Opportunity
Build rich applications for the cloud while preserving application symmetry with the enterprise
Frictionless deployment across the spectrum
New breed of applications that span from on-premises to cloud

11. Questions to Consider Application Portability Application Dependencies
Is the application cloud-ready?
Application Dependencies
Are application dependencies met?
Connectivity
Is application able to access required network resources?
Business and Regulation
Are all other considerations met?

12. Analyzing The Answers
In many cases, answers will not be clear Yes or No
The application could be a multi-tier service,
With mix of new cloud-ready code and existing code,
Where some components need to access resources in enterprise network,
Some components are chatty and latency sensitive,
And some of the application data may be subject to regulatory or other non-technical considerations.

13. Process Topology Cloud Readiness Connectivity Management
Create blueprint with location of each comp
Consider business and regulatory issues
Cloud
Readiness
Make each component cloud-ready
New/modified or virtualized code
Connectivity
Utilize connectivity, caching and sync techniques
Consider security and latency issues
Management
Deploy and monitor
Across locations per topology

14. Application Portability
Newly developed applications
.NET and managed code technologies
State separated code
Model-driven deployment
Existing applications and components
Modifying apps when possible – meet the cloud half-way
Machine and application virtualization technologies

15. Example: VM Support Virtual Machine Role Type
Helps easily move existing apps to cloud
Enables wide range of Windows apps to run in Windows Azure
Select Base Windows Server image
Install SW, Customize & Configure
Incorporate into cloud service model
Deploy & Manage Service

16. Application Dependencies
Making application code portable is only first step
Applications do not run in isolation
Need to access their data
Dependencies on run-time environments
Dependencies on network configuration
Dependencies on other services

17. Required Services and Connectivity
Increasing symmetry over time, e.g.,
SQL Server <-> SQL Azure
.Net +VS
Future – common models, end-to-end management
But required services may not be available
Options:
Co-locate application with required services
Access required services remotely
A combination of both options may be needed

18. Connectivity Data Synchronization Application Connectivity ServiceBus
Network Connectivity
Virtual Network Overlay

19. Virtualizing the Network
VIRTUAL NETWORK OVERLAY
ENTERPRISE
DEDICATED CLOUD
PRIVATE CLOUD
PUBLIC CLOUD
Cloud Network
Secure Cloud Federation

20. Business and Regulations
Regulations and certifications
SOX, HIPPA, PCI, etc.
Business requirements
Company policies, IT policies, etc.
Such requirements must be considered early
Can affect basic topology of the service, location of data, communication patterns
Off-premises clouds over time will gain more certification
But the need to keep on-premises data and computation will not go away

21. Putting It All Together
Examine app components, and communication paths
Ask the questions listed before
Decide on the overall topology
Make the code cloud ready
New code should be written with cloud in mind
Consider modifying or using virtualization for existing code
Connect the components based on selected topology
Use various connectivity solutions as needed
Be careful with latency and communication boundaries
Make sure remote components are not chatty
Use caching and data sync as appropriate
Remember security, business, and regulatory requirements
At a minimum, these will affect overall topology of the service

22. Beyond Bridging the Gap
Principles discussed enable moving apps to cloud
While bridging back to the enterprise
Current and future technologies for frictionless deployment and connectivity
Next: new transforming scenarios
Business continuity solutions
Collaboration scenarios
Extranet applications
Federation scenarios …
