THE TRADITIONAL SERVER CONCEPT SYSTEM ADMINISTRATORS OFTEN TALK ABOUT SERVERSAS A WHOLE UNIT THAT INCLUDES THE HARDWARE, THEOS, THE STORAGE, AND THE APPLICATIONS. SERVERS ARE OFTEN REFERRED TO BY THEIR FUNCTIONI.E. THE EXCHANGE SERVER, THE SQL SERVER, THE FILESERVER, ETC. IF THE FILE SERVER FILLS UP, OR THE EXCHANGE SERVERBECOMES OVERTAXED, THEN THE SYSTEMADMINISTRATORS MUST ADD IN A NEW SERVER. 20090909_VirtualizationAndCloud 4 5. THE TRADITIONAL SERVER CONCEPT Unless there are multiple servers, if a serviceexperiences a hardware failure, then theservice is down. System Admins can implement clusters ofservers to make them more fault tolerant.However, even clusters have limits on theirscalability, and not all applications work in aclustered environment.20090909_VirtualizationAndCloud 5 6. VIRTUAL SERVER CONCEPT 7. VIRTUALISATION 8. CLOUD COMPUTING 9. DEFINITIONCLOUD COMPUTING is the delivery ofcomputing as a service rather than a product,whereby shared resources software andinformation are provided to the computersand other devices over a network.Cloud is a large group of interconnectedcomputersCloud here is actually a metaphor of internet 10. Cloud computing architecture*. Cloud computing can be divided into two sections1. Front end2. back end*. Front end includes client computers*. Back end is the cloud section of the system*. The administrator uses a set of rules called protocolsand uses special kind of softwares called middleware forsmooth running and traffic control*. Middleware allows networked computers tocommunicate with each other. 11. CLOUD COMPUTING ARCHITECTURE 12. CLOUD COMPUTING SERVICESCloud computing providers offer their servicesaccording to three fundamental models Infrastructure as a service (IaaS) platform as a service (PaaS) software as a service (SaaS) 13. CLOUD COMPUTING SERVICES 14. CLOUD COMPUTING SERVICESIAAS- In this most basic cloud service model, cloud providers offercomputers as physical or more often as virtual machines , raw(block) storage, firewalls, load balancers, and networks. Cloudproviders typically bill IaaS services on a utility computing basisPAAS- In the PaaS model cloud providers deliver a computingplatform and/or solution stack typically including operating system,programming language execution environment, database, and webserver.SAAS- In this model, cloud providers install and operate applicationsoftware in the cloud and cloud users access the software fromcloud clients. 15. CLOUD COMPUTING SERVICES 16. ADVANTAGES1.Access you data all the times2.A physical storage centre is no longer needed3.Most have a pay structure that only calls for payment when used4.Relieves burden on IT proffesssional and frees up their time in office5.Easily scalable so companies can add or substract resources based on their own needsDISADVANTAGES1.Less control comes with handling over your data and information2.Dependence on a third party to ensure security and confidentiality of data and information3.Long term dependence on cloud host or maintainance o your information 17. ADVANTAGES AND DISADVANTAGES 18. APPLICATIONS 19. Conclusion Thus cloud computing provide a super-computingpower .This cloud of computers extends beyond a singlecompany or enterprise.The applications and data served by the cloud areavailable to broad group of users, cross-enterprise and cross-platform. </p>
