Gartner’s View of Clouds Gartner’s View of Clouds

“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, “By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets. ” “The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications. ”

Considerations: Cloud • • Lower cost: CAPEX, OPEX Greater agility Match capacity to demand Considerations: Cloud • • Lower cost: CAPEX, OPEX Greater agility Match capacity to demand How to leverage on-premises, public, private and dedicated cloud § Privacy of data § Latency/performance considerations • Meet requirements for secure communication and compliance • Increase speed to market • Handle complexity of SLA

Considerations: Cloud computing § Abstract Resources § Focus on your needs, not on hardware Considerations: Cloud computing § Abstract Resources § Focus on your needs, not on hardware specs. § On-demand Provisioning § Ask for what you need, exactly when you need it. § Large Scale § Cloud is conceptually of infinite capacity. § No Up-front Hardware Investment § Costs are in direct proportion to actual usage. § Cost-Effective & Efficient § No investment in depreciating hardware.

Virtually all the companies Cloud Considerations: Environmental Sustainability “Green IT has reached critical mass. Virtually all the companies we surveyed (97 percent) are discussing their Green strategy. ” “Green IT Report Regional Data – United States and Canada: Survey Results, ” Symantec, May 2009 “Transformation in the way people and businesses use technology could reduce annual man-made global emissions by 15 per cent by 2020 and deliver energy efficiency savings to global businesses of over EUR 500 billion [GBP 400 billion/USD 800 billion]. ” “SMART 2020: Enabling the Low Carbon Economy in the Information Age, ” The Climate Group, June 2008 “Enterprise PCs are wasting money. Far too many organizations leave economic and environmental value on the table by not reducing PC-related energy costs. ” “How Much Money Are Your Idle PCs Wasting? , ” Forrester Research, Inc. , December 2008 “IT's role will increasingly be about applying the technology to create more-energy- efficient, less-carbonintensive business models, enterprises, value chains, products and services with reduced environmental impact. ” “User Survey Analysis: Sustainability and Green IT, Worldwide, 2009, ” Gartner, Inc. , April 2009

When Is Cloud Computing Fit For The Enterprise? Applications & processes have highly variable When Is Cloud Computing Fit For The Enterprise? Applications & processes have highly variable demand High compute capacities are required to accelerate information discovery and publishing Time-constrained or event-based infrastructure is required to ramp quickly and be disposed of shortly afterwards Speed of provisioning is constraining business execution Existing hardware has reached end of serviceable life and refresh options are being considered Internal datacenter capacity limits are being reached and hosting locations must be re-balanced
