اسلاید 4: 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 5: 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 12: Slide 12Cloud ComputingWhat is the landscape of Cloud Computing?SaaS and IaaS are the key cloud capabilities for 80% of our customersApplications, typically available via the browser: Google Apps Salesforce.comSaaS(Software as a Service)Hosted application environment for building and deploying cloud applications: Salesforce.com 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 13: 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 14: Slide 14Cloud ComputingWhat are the benefits & challenges of SaaS?BenefitsSpeedReduced 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 15: 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 16: Slide 16Cloud ComputingWhat are the benefits & challenges of PaaS?BenefitsPay-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 17: 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 18: Slide 18Cloud ComputingWhat are the benefits & challenges IaaS?BenefitsSystems 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 33: Slide 33Cloud ComputingNew services will emergeCloud coverData Warehousing & Business Intelligence as a ServiceToday companies are challenged to find and build in-house expertise in both technologies, and expertise directly correlates with value. A service would obviate the large investment in people and technology focusing expenditures on resultsBusiness Process Outsourcing as a ServiceOutsourcing business processes requires adoption for the outsourcer or migration for the customer. Service enablement obviates the need for platform changes focusing instead on pushing data through the process in a seamless stream Business Continuity & Disaster Recovery as a ServiceClouds break the link between applications and hardware enabling lightening fast responses to outages and disasters without disruption. Billions of dollars spent provisioning “just in case” environments can be saved while improving service.Entrepreneurs identify new ways to leverage clouds to address corporate headaches

اسلاید 35: Slide 35Cloud ComputingAs part of an IT transformation adopting cloud would look something like this…Rationalize infrastructure & applicationsReduce the complexity by identifying redundant, outdated, or underperforming components and consolidate servers.Define the cloud architectureCreate a cloud architecture leveraging SOA for applications, utility computing for infrastructure, and ESB for integration with appropriate standards, governance, and reference architecturesBuild cost profiles for each applicationIdentify the costs to support, update, and operate each application on a per user basisIdentify and assess SaaS alternativesTarget SaaS alternatives offering a better economic model than internal hosting. If not available target SOA alternatives.Where do we start - the weather forecast
اسلاید 36: Slide 36Cloud Computing…and this…5.Migrate infrastructure to a cloud bursting modelFurther consolidate servers from just-in-case to average load provisioning using the internal pool of servers left over or an external IaaS provider to handle peak loadsIdentify systems management gaps and discuss with vendors6.Build new applications on a SOA foundation Applications requiring significant development or new applications should be constructed on a SOA foundation with a particular focus on application virtualization7.Create cloud enablement roadmap for retained applicationsDefine a development roadmap which migrates retained applications to a cloud model through outsourcing (SaaS), replacement (SaaS or SOA), or development (SOA).Where do we start - the weather forecast
