What is Cloud computingCloud computing means that infrastructure, applications, andbusiness processes can be delivered to you as a service, over theInternet (or your own network).The physical cloud resources may reside in a number oflocations, the details of which are not typically known to theservices users. 4. Why cloud computingCloud computing provides a way to increase capacity or addcapabilities on the fly without investing in new infrastructure,training new personnel, or licensing new software.Cloud computing is cost smart it is a pay-per-use service that, inreal time over the Internet, extends ITs existing capabilities. 5. Benefits of Cloud ComputingEase of UseScalabilityRisk freeReliabilityCost smart 6. Ease of useDeploy infrastructure easilyNo cabling, screwdrivers, racking, unboxing, buying hardware or /andsoftwareMiddle of the nightDo it yourself remotely from anywhere anytime 7. ScalabilityControl your infrastructureScale up/DownUpgrade as you growInstant 8. Risk freeNothing to buy/ maintain / fix .Cancel immediatelyChange instantly, even operating systemsNo need to worry about hardware failures 9. ReliabilityBased on enterprise grade hardware.Design to be failure free :Automatically spin up replacementsUse multiple clouds 10. CostYou pay only for what you use.You are billed on the amount of resourcesconsumed. 11. Anatomy of the Cloud 12. Layers of the CloudThe client layer acts as the user interface to which cloud computing services are delivered. Client layer hardware can include personalClient computers, web browsers, mobile devices, and even telephones.Cloud application services or "Software as a Service (SaaS)" deliver software as a service over the Internet, eliminating the need to install and run the application on the customers own computers and simplifying maintenance and Application support.Often referred to as the infrastructure layer, the virtualization layer is the resultThe Virtualization of various operating systems being installed as virtual machinesLayerThe servers layer consists of computer hardware and/or computer software products that are specifically designed for the delivery of cloud services, including multi-core processors, cloud-specific operating systems and combinedThe Hardware Layer offerings. 13.
