  • Dispelling the Fog About Cloud ComputingNovember 2, 2012 Dan Kusnetzky Founder

  • Required Cloud PictureEvery presentation on cloud computing simply must include a lovely photo of a cloud.

    Here's my photo of Siesta Key Beach in Sarasota, Fla.

    Now that is done, let's discuss the realities and myths of cloud computing.

  • What Is Cloud Computing?Cloud computing is an outgrowth of several longstanding trendsA slightly new way to address organizations' desire:To focus on their key points of added valueTo pass other functions on to others who can do them more efficiently and at lower costBased upon the intersection of:OutsourcingIncreased use of industry standard systemsIncreasingly virtualized environments

  • Attributes of Cloud ComputingCloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet).Usually these resources are:Self-provisionedPaid for using a utility model, paid by the useEasily scaled up or down as neededTypically a multi-tenant environment

  • Why Cloud Computing?Hardware, software & staff cost reductionNo more datacenter spaceNo budget for new equipment or staffAgilityRisk reduction

  • Public, Private, Hybrid Clouds:Where Is the Action?PublicPrivateHybrid

  • What's Holding Back Cloud Adoption?Concerns about:Cross-border data flowData securityRegulatory complianceLack of experienceLack of standards for migration and interoperabilityUnreasonable expectations

  • Emerging StandardsCloud Security AllianceCloud Standards Customer CouncilDistributed Management Task Force (DMTF)National Institute of Standards (NIST)Open Data Center Alliance

  • Emerging FrameworksOpen StandardsCloudStackOpenStackVendor frameworksAmazonEucalyptusMicrosoft Azul?VMware vCloud

  • Some SuggestionsIs this trip really necessary?Know where youre going, or you might end up somewhere else.Know what your organization really wants to accomplish, or you might not achieve your goals.Plan for security, reliability, or manageability!
