اسلاید ۴: Slide 4Cloud ComputingCloud Computing – The Coming StormWhat is Cloud Computing “Cloud” is the aggregation of Servers, Low end computers and storage hosting the program and data Accessed via Internet anywhere from world User Centric – Easier for group members to collaborate Task Centric – User’s need is more important than features of application Powerful – All resources together create a wealth of computing power Programmable – Automated distribution of computing power and data across cloud. Data loss become a history now

اسلاید ۵: Slide 5Cloud ComputingCloud Computing – The Coming StormWhat Cloud Computing “IS NOT” It is not Network Computing Application and Data are not confined to any specific Company’s Server No VPN Access Encompasses multiple companies, multiple servers and multiple networks It is not Traditional Outsourcing Not a contract to host data by 3rd party Hosting Business No subcontracting for computing services for specific outside firm

اسلاید ۱۲: Slide 12Cloud ComputingWhat is the landscape of Cloud ComputingSaaS and IaaS are the key cloud capabilities for 80% of our customersApplications, typically available via the browser: Google Apps SalSaaS(Software as a Service)Hosted application environment for building and deploying cloud applications: Sal Amazon E2C Microsoft AzurePaaS(Platform as a Service)Utility computing data center providing on demand server resources: HP Adaptive Infrastructure as a Service Rackspace Amazon E2C & S3IaaS(Infrastructure as a Service)Three primary models for Cloud Computing have emerged:Cloud Computing – The Coming Storm

اسلاید ۱۳: Slide 13Cloud ComputingSoftware as a Service (SaaS)Applications (word processor, CRM, etc.) or application services (schedule, calendar, etc.) execute in the “cloud” using the interconnectivity of the internet to propagate dataCustom services are combined with 3rd party commercial services via orchestration (SOA) to create new applicationsRequires investment to build an enabling layer with governance, security and data management functionalityMay require integration with back-office systemsPay-as-you-go modelSaaS will disrupt the application management functions for both internal IT and outsourcersCloud Computing – The Coming Storm

اسلاید ۱۴: Slide 14Cloud ComputingWhat are the benefits & challenges of SaaSBenefitsSpeedReduced up-front cost, potential for reduced lifetime costTransfer of some/all support obligationsElimination of licensing riskElimination of version compatibilityReduced hardware footprintChallengesExtension of the security model to the provider (data privacy and ownership)Governance and billing managementSynchronization of client and vendor migrationsIntegrated end-user supportScalabilityStrong governance required to prevent lines of business from purchasing application services externally without IT involvementCloud Computing – The Coming Storm

اسلاید ۱۵: Slide 15Cloud ComputingPlatform as a Service (PaaS)Applications are built in the “cloud” on the platform using a variety of technologiesSimplifies orchestration of cloud servicesDevelopment, testing, and production environments (servers, storage, bandwidth, etc.) are billed monthly like hostingPay-as-you-go modelEnvironments scale up & down at the click of a buttonConcerns include code & data privacy, security and scalabilityPaaS will disrupt the application development and management functions for internal ITCloud Computing – The Coming Storm

اسلاید ۱۶: Slide 16Cloud ComputingWhat are the benefits & challenges of PaaSBenefitsPay-as-you-go for development, test, and production environmentsEnables developers to focus on application codeInstant global platformElimination of H/W dependencies and capacity concernsInherent scalabilitySimplified deployment modelChallengesGovernanceTie-in to the vendorExtension of the security model to the providerConnectivityReliance on 3rd party SLA’sStrong governance required to prevent lines of business from building applications without IT involvementCloud Computing – The Coming Storm

اسلاید ۱۷: Slide 17Cloud ComputingInfrastructure as a Service (IaaS)Compute resources (processors, memory, storage, bandwidth, etc.) are provided in an as-needed, pay-as-you-go modelAble to provide from single server up to entire data centersCreates new opportunities such as Cloud bursting: shifting usage spike traffic to alternate resources Infrastructure scales up and down quickly to meet demandBuilt on a utility computing architecture to host a SOA application layerIaaS will disrupt the infrastructure management functions for both internal IT and outsourcersCloud Computing – The Coming Storm

اسلاید ۱۸: Slide 18Cloud ComputingWhat are the benefits & challenges IaaSBenefitsSystems managed by SLA should equate to fewer breaches Higher return on assets through higher utilizationReduced cost driven byLess hardwareLess floor space from smaller hardware footprintHigher level of automation from fewer administratorsLower power consumptionAble to match consumption to demandChallengesPortability of applicationsMaturity of systems management toolsIntegration across the Cloud boundaryExtension of internal security modelsIaaS is the onramp for corporate IT to Cloud Computing!Cloud Computing – The Coming Storm

اسلاید ۱۹: Slide 19Cloud ComputingHow do SaaS, PaaS, and IaaS compareSaaSEasy first step to adopt alternative desktop office applicationRequires nothing more than a credit card to startWill drive home the SOA value propositionPaaSAimed primarily at small & new companies but models apply to allLarge companies will benefit as services scale up and model is driven into internal software development tools and processesIaaSGalvanizing approach to Utility Computing to drive high ROAOverflow to external provider to avoid cap-ex to meet peaksLonger term play due to immature tools and resistance to changeCloud Computing – The Coming Storm
