This document discusses server virtualization. It begins by defining server virtualization as allowing multiple operating system instances to run concurrently on one physical server by creating multiple logical server OS instances. It notes the benefits of server virtualization include consolidation, redundancy, and migration. It outlines the types of virtualization as full virtualization using a hypervisor, paravirtualization where guests are aware of each other, and OS-level virtualization without a hypervisor. Applications of virtualization include virtual private servers and parallel OS environments. Limitations include unsuitability for applications requiring high processing power and disk space. The future of virtualization includes more integration.

2. Contents Introduction. Need. Types. Applications. Limitations. Future Scope. Conclusion. References.

3. Introduction Server machine that host file and application. Usually dedicated to an application. Fig:Server

4. Server Virtualization Allows multiple operating instances to run concurrently. Creating multiple logical server OS instances on one physical piece of hardware

5. Need Consolidation. Redundancy. Migration.

6. Consolidation Combination of several machines into one single server. Fig: Consolidation

7. Redundancy It refers to running same application on multiple server Fig: Redundancy

8. Migration Migration refers to moving a server environment from one place to another. Fig: Migration

9. Types Full virtualization Para virtualization OS-level virtualization

10. Full Virtualization It uses special kind of software called HYPERVISOR. It runs multiple applications simultaneously. Fig: Full virtualization

11. Para Virtualization every guest is aware of other guests server’s. Fig: Para virtualization

12. OS level Virtualization No hypervisor used here. Has a homogeneous environment. Fig: Os level virtualization

13. Applications Virtual Private Server. Parallel OS environments.

14. Virtual Private Server. Running different guest on the same physical server. Cost Effective Less expensive Fig: Virtual private server

15. Parallel OS environments. Can run different OS services independent of the server used. Single Physical Server Linux Server Windows Server Parallel OS Environments SharePoint Server

16. Limitations Not suitable for application requiring high processing power Not suitable for limited disk space hard drives Migration is another problem for different processors

17. Future Scope Fig: Msbte’s result plan

18. Conclusion Server virtualization is a strategic direction for managing servers. It reduces the cost of hosting and managing servers Managing a pool of identical servers simplifies operating procedures.
