- 3. PerspectiveWhat is Virtualization?Virtualization means splitting up a single physical computer into several “virtual” computers.
- 4. Each virtual operating system is a called a virtual machine(vm's) which is just a collection of files on a physical machine. WHY VIRTUALIZATIONConsolidation
- 5. Redundancy
- 6. Segregation
- 8. MigrationVirtualization -- a Server for Multiple Applications/OSApplicationsApplicationsApplicationsApplicationsApplicationsApplicationsOperatingSystemOperatingSystemOperatingSystemOperatingSystemOperatingSystemOperatingSystemHardwareHypervisorHardwareHypervisor is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system. The hypervisor manages the system's processor, memory, and other resources to allocate what each operating system requires. Hypervisors are designed for a particular processor architecture and may also be called virtualization managers.

CONCEPTUALIZATIONTRADITIONAL SERVER CONCEPTExpensive to acquire and maintain hardwareNot very scalableDifficult to replicateRedundancy is difficult to implementVulnerable to hardware outagesIn many cases, processor is under-utilizedVIRTUAL SERVER CONCEPTHighly redundantHighly availableRapidly deploy new serversEasy to deployReconfigurable while services are runningOptimizes physical resources by doing more with less

- 13. CLOUD COMPUTINGCloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like electricity.

- 15. SaaSSoftware delivery modelNo hardware or software to manageService delivered through a browserCustomers use the service on demandInstant Scalability
- 16. PaaSPlatform delivery modelPlatforms are built upon Infrastructure, which is expensiveEstimating demand is not a science!Platform management is not fun!
- 17. IaaS Infrastructure delivery modelA platform virtualization environmentComputing resources, such as storing and processing capacity.Virtualization taken a step further

- 20. Public cloud (a.k.a. External Cloud)
- 21. Sold to the public, mega-scale infrastructure
- 22. Hybrid cloud
- 23. composition of two or more cloudsDifference Virtualization Virtualization is creating virtual versions of technologies like servers, operating system, network resources &storage devices.In virtualization, either its one operating system using multiple computers to evaluate database or a single computer controlling several machinesCloud Computing Cloud Computing make use of virtualized resources such as servers, computing devices and networks In Cloud Computing a database can be physically located somewhere in secure remote location and data can be accessed through clients computer using the database server to analyze and recover the data.
- 24. BENIFITSReduction in cost of infrastructure.Enhances flexible functionality of management.High accessibility of applications and data.Improves system compliance.Improved System Reliability and Security.
