be“proven”IaaS is in the process of to maturing and gaining acceptancePaaS is the most challenging in-terms of maturity,acceptance,and adoption微软IT云服务综述CurrentCurrent/EmergingEmerging/NascentModelSoftware as a Service(SaaS)Data Center as a Service(DCaaS)Infrastructure as a Service(IaaS)Platform as a Service(PaaS)DescriptionSaaS describes a model where a“finished service”is available,typically not on-premise,allowing a customer to simply connect and use nearly on-demand and with a minimum of investmentDCaaS is the traditional server hosting scenario:You bring the equipment to a hoster that can provide a suitable facility,base management services,and meet your SLA requirementsIaaS is creating a“datacenter within a datacenter”that can run most IT workloads on common platforms,without disruption to the current application designs and modelsPaaS may require application redesign/recoding and significant process/workflow changes for the full benefit of some scenarios to be realized,at least in current implementationsCurrentMicrosoft IT consumes some BOS services,such as Exchange(e-mail and collaboration)and client desktop managementMicrosoft IT already utilizes Global Foundation Services(GFS)as a DCaaS provider for shared facilitiesMicrosoft IT already has infrastructure designs and services that fall into this category:Scale Unit infrastructure and Utility ServicesMicrosoft Consumer and Online Services are driving in this direction for web-based services that lend themselves well to the Azure platformFutureMSIT should continue to leverage BOS where possible and should be encouraged to find new opportunities to consume partner-delivered finished services in the futureIf GFS and/or current MSIT providers cannot meet future-oriented requirements,we need to acknowledge this and decide whether to choose a new course MSIT should continue to pursue IaaS as a way to enable an“Enterprise Cloud”,getting traditional IT customers into a modern managed infrastructureMSIT is actively looking for applications suitable for Azure,but adoption will be much more intentional and it will require changes to our SDLC2/26/20247微软内部IT虚拟化现状VMs make up more than 30%of our total server population,inclusive of virtualization hostsAbout 1500 physical servers host nearly 7000 VMsHighest VM concentrations are in enterprise datacentersPrevious consolidation efforts have limited regional sprawlWhere field services and applications are needed,we now deploy a“Virtual Branch Office Server”(VBOS)to replace legacy User Services Platforms(USPs)New demand for a scalable HA configuration for MS Retail and hub sitesGoal of the VM hosting service is to equal or better the service level and value of traditional physical serversAvailability averaged 99.95%,even prior to HA VM configurationsVM hosting is 50%of the cost of a comparable physical serverTargeting 50%virtualized in CY2010 and greater than 80%in the 2011-2012 timeframeOn-boarding process steers appropriate candidates into VMs for all new growth and hardware refresh/migration requirements2/26/20248Microsoft Confidential

usersProduction VDI solution being provided for offshore vendor/partner scenariosDeveloping scenarios and business cases for task-based workers and employees needing multiple PCsWorking with Client Services to fit VDI into their roadmap and service model2/26/202417MSIT虚拟化应用M 100%虚拟化Primarily web and SQL workloadsCompute and SAN storage platforms very similar to MSIT EnterpriseAmount of RAM per

constraintsAutomation leverages System Center and some custom tools for self-serviceDDTK and Visual Studio 2010 Lab Management is targeted for future adoption2/26/202419MSIT 云概念Service-oriented infrastructure capabilitiesSubscription,rather than utility,mindsetLike a media/communications plan,rather than on/off like a infrastructure utility like water/powerStandardized and bundled offerings,plus options“Basic,Expanded,Silver,Gold,Platinum”Defines capabilities,SLA,costProcess optimization around standards and servicesTool selection is not dictated by current(legacy)processProcess is not designed around tool limitationsTools enable template-based automationFor example,ordering a new server would be a defined workflowAll necessary information would be captured up-frontTodays process of multiple requests/tickets driving manual tasks is replaced by a workflow that drives the end-to-end sequence2/26/202420MSIT 云战略Build and run a production quality incubation environment,with the purpose of piloting new technologies and techniques that further dynamic infrastructure goalsSeek out and adopt products that facilitate service-oriented,rather than device or element level,management techniques Compute,Network,Storage,and Management as a service Present the new environment as a flexible subscription model,rather than simplistic utilityNot“one-size-fits-all”,but a set of capabilities that can be offered in cumulative combinations and priced accordinglyContinue to adopt SaaS via BPOS and PaaS via Azure where it makes sense,but where this is not practical or possible fill the gap with a true on-premise“Enterprise/Private Cloud”that displaces the legacy IT environment2/26/202421MSIT 云设计原则DISCUS will describe a set of global server environment infrastructure standardsCombined infrastructure and service designs should inherently support the resiliency/redundancy and availability requirements of greater than 80%of production server applications and services Technology and tool selection will not be limited by legacy adoption practices or processSeek out“best fit”solutions capable of meeting the goals with an acceptable level of investmentMicrosoft solutions preferred,if they exist and satisfy the requirementsPartner solutions are acceptable,particularly if they are superior to a MS-only offeringInfrastructure elements are architected and engineered in a“better together”fashionThe solution is designed to facilitate capacity management,procurement,and implementation in a unified and consistent manner2/26/202423MSIT 云发展路标Current StateFY 11FY12-Infrastructure Optimization Model 80%of Standardized achieved-Infrastructure Optimization Model Standardized transitioning to

commodity production environment-Most platform pilot and some dogfooding done more efficiently in controlled“incubation”production environment-All platform pilot work and most dogfooding done very efficiently in incubation environment-Semi-automated and manual provisioning-Automated provisioning and MAC by administrators-Self-service enabled provisioning and MAC for limited customer set-Applications not taking advantage of improved platform capabilities Performance,availability,flexibility-Focused effort to get selected applications to take advantage of improved platform capabilities-New applications inherently take advantage of improved platform capabilities-Confusion over appropriate platform and implementation models to adopt Legacy IT?Dynamic on-premise(Private Cloud)IT?Azure external cloud?Other?-Clearer guidance and a resourced onboarding path for new applications or those undergoing platform refresh-Appropriate platform selection is ingrained into application design/development/requirements and onboarding flow takes care of the process in an elegant way2/26/202424 2006 Microsoft Corporation.All rights reserved.This presentation is for
