Intel’s cloud computing taxonomy classifies the breadth of existing cloud technologies. IT@Intel Brief www.intel.com/it Intel IT Capability Frameworks Intel IT has developed several capability frameworks that assist our planning and decision making. These frameworks provide important structure, which promotes understanding and alignment of top-level IT capabilities across the enterprise and the supporting ecosystem. We based our cloud computing taxonomy segmentation partly on these frameworks. Intel IT uses three frameworks, each representing a different area of focus: Enterprise Capability Framework (ECF) holistically describes all of Intel’s business capabilities along with corresponding IT capabilities, such as design, supply chain planning, and human resources. Cross-Enterprise Capability Framework (xECF) describes the non- infrastructure technical capabilities used across many business functions, such as instant messaging or e-mail. Infrastructure Services Framework (ISF) describes infrastructure capabilities, such as servers, data centers, and laptops. Background Thecloudcomputingmarketisevolvingrapidly, withafast-growingnumberofexternalcloud servicesandenablingtechnologies.Thiscreates aneedfortoolsthatIntelcanusetobetter understandthemarket,defineinternalITand externalcloudcomputingstrategy,andfacilitate adoptionofcloudcomputingservicesthatmeet ourneeds. Taxonomies,whichareclassificationsbased onahierarchicalstructure,havetraditionally beenusedtounderstandtechnologymarket segmentationandgeographicbreakdown, evaluatesuppliers,andmappotentialusageto theavailabletechnologies.Anotherimportant advantageoftaxonomiesisthattheyprovidea commonterminologytofacilitateunderstanding andcommunication. Fromtheperspectiveofcloudadoption,the cloudecosystem—includingserviceproviders, endusers,developers,andadministrators—has anaturalevolvingorderthatcanberepresented bytaxonomy.However,thoughseveralcloud taxonomiesalreadyexist,noneofthem providesacomprehensiveanalysisoftheentire marketthatcanbeusedbygroupsacrossIntel, includingIntelIT. Intelthereforeformedacross-organizational team,includingmembersfromIntelIT,Intel SoftwareandServicesGroup(SSG),andIntel DataCenterGroup(DCG),todevelopasingle cloudcomputingtaxonomyforuseacrossIntel. Ourgoalsweretoprovidecommon,standard terminology;helpunderstandtherapidly evolvingmarket;andidentifykeysuppliersas wellasproductsthatmeetourneeds.Steps includeddefiningtheprimarycategoriesof cloudcomputingservice,segmentingthese intosubcategories,andcreatinganecosystem analysisofthesupplierswithineachcategory.
