IBM Cloud computing is an IT service delivery approach that often brings a challenging set of decisions which require a structure and framework to address Service Delivery Framework providing structure to complexity Strategic Decisions Considerations Business Design Service Level Deployment Characteristics Outcomes Economics AccountabilityPerformance SecurityShared Location FlexibilityAvailability Cloud Computing is an evolving delivery approach outcomes economics accountability availability security performance flexibility location Decisions Shared Multi-tenant Deployment models Hybrid Governance Migration Management Roadmap Ownership Planning Computing Considerations Business Design Service Level Deployment Characteristics Cloud

IBM There are three areas of strategic decisions that need to be considered during transformation Aligning business strategy to expected service delivery outcomes while optimizing the economics and risks / rewards of delivery What type of availability is required and what are the associated security assurances that are essential while maximizing performance Balancing the choices relative to the flexibility of deployment models, shared environments as well as the location of infrastructure and application assets IBM has developed a Service Delivery Framework aggregating these considerations Strategic Decisions Business Design Service Level Deployment Characteristics

IBM Strategic Decisions Considerations Business Design Service Levels Deployment Characteristics Outcomes Economics AccountabilityPerformance SecurityShared Location Flexibility Availability During transformation the IBM Service Delivery Framework extends the strategic decisions by further defining the requirements, preferences and optimization.

IBM Innovation drives Business Design, which in turn, aligns to expected service delivery outcomes, economics and accountability.

IBM Performance has a broader meaning with new cloud flexibility which is as much service performance as response time.

IBM You need to balance choices relative to the flexibility of Deployment Models, shared environments including location of infrastructure and application assets. Location Client Site Vendor Site Location of assets are key to aligning requirements to the purchase / control of infrastructure versus leveraging a third party infrastructure with less control but greater scalability Shared Dedicated Enterprise Shared Enterprise More control Different service delivery models can leverage dedicated environments versus shared environments – trading off control, cost, performance and scalability Less control $$$ $ Flexibility Elasticity Public Private Service delivery models can be designed to support highly elastic applications, while allowing for portability across delivery models to maximize utilization and economics Portability Deployment Characteristics
