Virtualization

Definition in simple terms referring to practical understanding:

Process of separating physical components of computing infrastructure from the logical components that demand the resources.

1. Types of Virtualization:
   1. Server :  Where you use Virtual machines to separate hardware from virtual operating systems, allowing you to run the multiple operating systems on a single machine, all at the same time.
   2. Storage:  Removing physical mapping of storage and moving storage into logical objects, which can be easily managed
   3. Network: process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. There two types of N/W Virtualizations
      1. Internal: Network functionality provided by software
      2. External: combining multiple network functions into one unit
   4. Application: Process of encapsulating applications to be able to run on another system without actually installing them, allowing applications to run without conflicts
   5. Desktop: consolidation of desktop computers into virtualized server systems

2. How server virtualization can help?….
   1. Consolidate data center servers, desktops,
   2. efficient h/W resources utilization,
   3. less energy and cooling,
   4. less IT staff to maintain and increased IT productivity
   5. respond faster to business needs by faster server deployments
   6. HA and load-balancing
