Private sector businesses and Government departments around the world are under pressure to achieve the improbable - deliver improvements in the quality of services to citizens while finding sizeable cashable efficiency savings. Cloud computing is a paradigm shift in the way information management systems are architected and is heralded as the saviour of IT budgets. So what are the practical operational advantages of Cloud technology?

This paper examines nine very good reasons why it makes sense to take cloud computing seriously.

WHITE PAPER | Cloud 9: Nine Reasons to Take the Cloud Seriously Overview The IT industry has put its Private sector businesses and Government departments around the world are under marketing machine behindpressure to achieve the improbable - deliver improvements in the quality of services cloud computing making it to citizens while finding sizeable cashable efficiency savings. Cloud computing is a one of the biggest IT hype curves ever. So does theparadigm shift in the way information management systems are architected and is cloud have a silver lining? heralded as the saviour of IT budgets. So what are the practical operational advantages of Cloud technology? This paper examines nine very good reasons why it makes sense to take cloud computing seriously. 2010 Encanvas Inc.3 4. WHITE PAPER | Cloud 9: Nine Reasons to Take the Cloud SeriouslyIntroductionWhat is the cloud?The cloud is used in computing context as a metaphor for a virtualized computingCloud computing versus webserver hosting whats the system that is seemingly always available to users anywhere and at any time.difference? Instead of procuring and maintaining web server platforms internally,organizations and individuals are able to procure their computing resources on apay-for-use basis.The essential difference between virtualized cloud computing infrastructures andtraditional web hosting is the ability of this new genre of platforms to poolresources between different tenants and applications (so-called multi-tenantapplications). A componentization of hosting resource building blocks means thatif one tenant requires more computing capacity while another wants less, theplatform is able to bring its capacity to bear as required. This means thatutilization of computing resources is optimized while the experience for tenants isthat applications can seemingly scale forever without thoughts or concerns overprocessing capacity, memory capacity or other such non-trivial matters thatwhilst important are not core to their business.With the cloud comes a new bag of technologiesDiscussions on cloud computing inherit topics related to the advancement ofweb-based technologies that have occurred over recent years such as theemergence of Web 2.0 applications and AJAX web programming that enablemore fluid user interface experiences. Adoption of programming innovations andsmarter ways of using known technologies finding better ways to createapplications, deploy applications, secure applications etc. means that cloudcomputing is no longer simply about infrastructure and hosting, it represents acollection of new technology-led approaches. 2010 Encanvas Inc.4 5. WHITE PAPER | Cloud 9: Nine Reasons to Take the Cloud Seriously The fundamental pillars of cloud computing are: Infrastructure as a Service Delivering the multi-tenant hosting environment and providing appropriate levels of backup, storage, security provisioning, processing capacity, resource pooling etc. supplied to tenants on a pay-for-use basis. Examples include Amazon EC2, theRackspaceCloud and Microsoft Azure. Platform-as-a-Service Applications platforms are a new concept in computing. They are software platforms that manage the life-cycle of applications design, deployment and operation in a single integrated platform that are charged to customers on a pay- for-use basis. Examples include Salesforce.coms Force.com, Encanvas Secure&Live, Microsoft Azure AppFabric and Google AppEngine. Software-as-a-Service These are applications delivered to customers on the cloud in the form of a service made available on a pay-for-use basis. There are a number of organizations that now provide SaaS platforms that house a number of applications. Examples include iGoogle, Zoho, Squork, Salesforce and 37signals. Types of cloud A cloud for every occasion In a little over a year since the beginning of its hype-curve , the IT industry has begun to make sense of definitions of what a cloud i. Types of cloud have emerged all of which are using the same platform architectures but are providing deployment options geared to suit differing user communities. These are: Public CloudCloud platforms that share their resources with public tenants where tenant might be an individual or organizations. Private Cloud Cloud platforms that are provided by a cloud service provider for the exclusive use of an organization for their community of tenants. Custom CloudA custom cloud is a platform based on cloud technologies deployed by an organization itself rather than hosted by a third party. This scenario is more prevalent in highly secure environments such as defence and government installations where the likelihood of third parties accessing data is of too great a risk to consider. 2010 Encanvas Inc. 5 6. WHITE PAPER | Cloud 9: Nine Reasons to Take the Cloud SeriouslyThe 9 Good Reasons1. Clouds cost lessThe obvious benefit of cloud computing are associated with infrastructure savingswhen compared to traditional in-sourcing of hosting for business applications.For organizations that insource their information systems hosting, it meanslargely removing (not off-setting) costs such as: No on-site hosting hardware and softwareo Associated procurement costso Configuration costso Maintenance costso Power costso Upgrade costso Disaster recovery and backup provisioning No associated staff costso Recruitmento Salary and benefitso Training and technical qualificationso Successiono Associated risks brought about by dependencies on staff skills(people leaving or sick that possess essential knowledge of howhosting platforms are configured and how they operate) No facility related costs o Physical office space o Site security o Site heating and lightingIn addition to cost reductions, virtual hosting brings additional advantages ofreducing risk by: Removing knowledge bleed (particularly implicit knowledge the knowledge people carry around in their heads) Removing risk of a fire or natural disaster that destroys the hosting siteCloud computing gives Removing risk of loss of data due to external attack, mistakes ororganizations of any sizeinterventionsaccess to the latesttechnology for theirAdopting a cloud computing service can mean that organizations inheritinformation managementtechnology leadership and competencies they could scarcely afford for theirsystems. In this way itdemocratizes IT.business directly but benefit from the economies of scale enjoyed by vendors topursue excellence in IT hosting approaches with the revenues to fund innovationat a faster pace. 2010 Encanvas Inc.6 7. WHITE PAPER | Cloud 9: Nine Reasons to Take the Cloud SeriouslyIs Cloud Computing good news for organizations that use external hosting?While the rewards of movingto cloud computer are fewer Arguments for cloud hosting services are compelling when compared tofor already virtualized traditional in-sourcing. But what about organizations that have already migratedoperations, there are stilleconomic advantages to be to hosted service provision? How do the economic benefits of the cloud stack uprealized. then?For organizations that are already to some extent virtual it comes down to scaleof economies and the agility of cloud computing to enable EVEN morevirtualization.The cloud enables the outsourcing of more applications and greater optimisationof shared resources so that organizations have the opportunity to port moreapplications to a hosted model, and theyre able to call on more resources as theyneed them (on-demand) without having to anticipate a ceiling in capacity broughtabout by the capacity limits of the hosted environment. For organizations thathave already adopted hosting services then, the economies are not as clear-cutbut the scope for economies is greater.2. Clouds are easier to manageOnce applications are up and running on the cloud, day-to-day governance andmanagement is easier.Modern cloud computing platform offer very sophisticated administrationdashboards and performance intelligence to enable tenants to easily understandtheir utilization.Porting to the cloud normally reduces the number of technology vendors andpartners required to support the enterprise. This means associated costs ofmanaging vendor relationships are reduced.3. Clouds help to make corporate IT cost less and are easier to budgetThrough cloud computing, organizations are lowering their total IT costs to lessthan 1% of total business income (so if youre spending more than that on IT itsworth considering. Adopting cloud services means tenants dont pay for what Cloud computing removes the need for just-in-casethey dont use. Traditional internally hosted solutions have meant in the past that processing power.organizations have had to buy much more processing capacity than they reallyneed on a day-to-day basis just-in-case of growth and to cope with peaks andtroughs in demand. Its also been difficult for IT managers to configure theirhosting applications in such a way that applications are able to share availableprocessor, memory and storage between applications and between departments.This has meant organizations are housing, powering and maintaining many moreservers and much higher levels of capacity than they n
