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

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

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

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

Spectrum Extending Into the Cloud Virtualized Datacenter Utilization Increases to >50% Management Costs Decrease Private Cloud Management Costs Decrease Significantly Scale-out Development Expense Public Cloud Capacity on Demand Global Reach Traditional Datacenter Virtualized Datacenter Private Cloud

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

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?

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.

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

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

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

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

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

Connectivity Data Synchronization Application Connectivity ServiceBus Network Connectivity Virtual Network Overlay

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

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

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

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 …
