  • Vitual cloud

    1. 1. TECHNOLOGIES ON<br />CLOUD COMPUTING<br />ByB.P.SREEJITH VIGNESH<br />(LECTURER)SRI VENKATESWARA COLLEGE OF COMPUTER APPLICATIONS & MANAGEMENT.<br />COIMBATORE.<br />
    2. 2. EMERGENCE<br />It’s a long way of Computing scenario<br /> SCIENCE for KNOWLEDGE<br /> SCIENCE for SOLUTIONS<br />Virtualization<br />
    3. 3. Perspective<br />What is Virtualization?<br /><ul><li>Virtualization means splitting up a single physical computer into several “virtual” computers.
    4. 4. Each virtual operating system is a called a virtual machine(vm's) which is just a collection of files on a physical machine. </li></li></ul><li>WHY VIRTUALIZATION<br /><ul><li>Consolidation
    5. 5. Redundancy
    6. 6. Segregation
    7. 7. Legacy Hardware
    8. 8. Migration</li></li></ul><li>Virtualization -- a Server for Multiple Applications/OS<br />Applications<br />Applications<br />Applications<br />Applications<br />Applications<br />Applications<br />Operating<br />System<br />Operating<br />System<br />Operating<br />System<br />Operating<br />System<br />Operating<br />System<br />Operating<br />System<br />Hardware<br />Hypervisor<br />Hardware<br />Hypervisor is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system. <br />The hypervisor manages the system's processor, memory, and other resources to allocate what each operating system requires. <br />Hypervisors are designed for a particular processor architecture and may also be called virtualization managers.<br />
    9. 9. CONCEPTUALIZATION<br />TRADITIONAL SERVER<br /> CONCEPT<br />Expensive to acquire and maintain hardware<br />Not very scalable<br />Difficult to replicate<br />Redundancy is difficult to implement<br />Vulnerable to hardware outages<br />In many cases, processor is under-utilized<br />VIRTUAL SERVER<br /> CONCEPT<br />Highly redundant<br />Highly available<br />Rapidly deploy new servers<br />Easy to deploy<br />Reconfigurable while services are running<br />Optimizes physical resources by doing more with less<br />
    10. 10. The Virtualization Types<br />Server Virtualization<br />Storage Virtualization<br />Network Virtualization<br />Application Virtualization<br />
    11. 11. Popular hypervisors<br />Xen<br />KVM<br />QEMU<br />virtualBox<br />VMWare<br />
    12. 12. Issues in Virtualization for Cloud-Computing<br />Software deployment<br />Open-source<br />Commercial products<br />Re-installation or not <br />Compatibility <br />Legacy software/database<br />virtualized resources as a <br /> service over the Internet.<br />Virtualization<br />
    13. 13. CLOUD COMPUTING<br /><ul><li>Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like electricity.
    14. 14. you pay-as-you-go and use only what you need, all managed by a browser, application or API.</li></li></ul><li>LAYERS<br />
    15. 15. SaaS<br />Software delivery model<br />No hardware or software to manage<br />Service delivered through a browser<br />Customers use the service on demand<br />Instant Scalability<br />
    16. 16. PaaS<br />Platform delivery model<br />Platforms are built upon Infrastructure, which is expensive<br />Estimating demand is not a science!<br />Platform management is not fun!<br />
    17. 17. IaaS<br /> Infrastructure delivery model<br />A platform virtualization environment<br />Computing resources, such as storing and processing capacity.<br />Virtualization taken a step further<br />
    18. 18. Cloud Deployment Models<br /><ul><li>Private Cloud (a.k.a. Internal Cloud)
    19. 19. enterprise owned or leased
    20. 20. Public cloud (a.k.a. External Cloud)
    21. 21. Sold to the public, mega-scale infrastructure
    22. 22. Hybrid cloud
    23. 23. composition of two or more clouds</li></li></ul><li>Difference <br />Virtualization<br /> Virtualization is creating virtual versions of technologies like servers, operating system, network resources &storage devices.<br />In virtualization, either its one operating system using multiple computers to evaluate database or a single computer controlling several machines<br />Cloud Computing<br /> Cloud Computing make use of virtualized resources such as servers, computing devices and networks<br /> 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.<br />
    24. 24. BENIFITS<br />Reduction in cost of infrastructure.<br />Enhances flexible functionality of management.<br />High accessibility of applications and data.<br />Improves system compliance.<br />Improved System Reliability and Security.<br />
    25. 25. ADOPTERS<br /> Microsoft Virtual Environment<br />desktone Virtual Cloud model<br />
