  3. 3. A Server is a computer program that provides services to other computer programs (and their users) in the same or other computers. Virtualization is a method of running multiple independent virtual operating systems on a single physical computer. It is a way of maximizing physical resources to maximize the investment in hardware. Fig 1:A general server 3
  4. 4. Fig 2:A General Virtualization concept 4
  5. 5. Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. Fig 3: Virtual Server 5
  6. 6. There are three popular approaches to server virtualization: The virtual machine model,  The paravirtual machine model, and  Virtualization at the operating system (OS) layer. 6
  7. 7. Virtual machines are based on the host/guest paradigm. Each guest runs on a virtual imitation of the hardware layer. This approach allows the guest operating system to run without modifications. It's not running on real hardware. It uses a hypervisor to coordinate instructions to the CPU. The hypervisor is called a virtual machine monitor (VMM). VMware and Microsoft Virtual Server both use the virtual machine model. 7
  8. 8. Fig 4: Virtual Machine Model 8
  9. 9. The paravirtual machine (PVM) model is also based on the host/guest paradigm. The VMM actually modifies the guest operating system's code. This modification is called porting. Porting supports the VMM so it can utilize privileged systems calls sparingly. Xen and UML both use the paravirtual machine model. 9
  10. 10. Fig 5:Para Virtual Machine 10
  11. 11. Virtualization at the OS level works a little differently. It isn't based on the host/guest paradigm. In the OS level model, the host runs a single OS kernel as its core and exports operating system functionality to each of the guests. Virtuozzo and Solaris Zones both use OS- level virtualization. 11

  13. 13.  Reduces administrative efforts ◦ Lowers operational costs  Fewer servers to manage ◦ Speeds deployment  Now 1-6 weeks (requisition, setup, software, test)  Virtual reduces this to hours  Reduced hardware and infrastructure costs  Improves resource utilization  Increases availability  Tools to enhance security 13

  15. 15.  Server consolidation  Multiple OS & application support  Lab and deployment testing  Help desk  Application isolation  Security  Disaster recovery 15
  16. 16. 16 Fig 7: Disaster Recovery
  17. 17.  Fewer servers to manage and recover/restore ◦ Reduces costs  Server VMs are hardware independent ◦ Can be restored to other platforms ◦ No need to match primary site and secondary site hardware  VMs are encapsulated ◦ Faster ◦ Can be replicated between sites ◦ No need for bare-metal installs 17
  18. 18.  Physical-to-VM recovery ◦ Restore physical backup to running VM ◦ Lower costs – no need for 1-to-1 physical servers  VM-to-VM recovery ◦ Protects against operating system/application failure ◦ Recover failed VM on another server 18
  19. 19. Server virtualization can be viewed as part of an overall virtualization trend in enterprise IT that includes storage virtualization, network virtualization, and workload management. Server virtualization can be used to eliminate server sprawl, to make more efficient use of server resources, to improve server availability, to assist in disaster recovery, testing and development, and to centralize server administration. 19
  20. 20. Server Virtualization is the perfect solution for applications that are meant for small- to medium-scale usage. Munich - Fujitsu announced a new initiative aimed at helping small and mid-size businesses (SMBs) take advantage of the business-boosting benefits of switching to server virtualization. ‘My Very First Hyper-V’ combines hardware and software components to provide an affordable, easy-to-manage entry point to server virtualization, offering SMBs significantly-reduced fixed and operational costs, as well as increased system flexibility and availability. 20
  21. 21.  Establishment of large organization will not cost too much due to deployment of virtual servers.  Data security issues will be fixed easily by storing the data on the virtual servers.  As in the data communication process there will be only one physical server so traffic load will be reduced.  Time paid to recovery of data in disaster situations like system or server crash will be reduced.  Productivity of the organization will be increased. 21
  22. 22. 1. Server Virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. 2. There are three popular approaches to server virtualization: The Virtual machine model, The Para virtual machine model, and Virtualization at the operating system (OS) layer. 3. Benefits of Server Virtualization are reduction of administrative efforts, Lowering operational costs, reduced hardware and infrastructure costs, Tools to enhance security and disaster recovery. 4. As in the data communication process there will be only one physical server so traffic load will be reduced. 22
