VIRTUALIZATION

VIRTUALIZATION

1. Process of running a virtual instance of a computer system in a layer abstracted from the actual hardware

2. Reduced capital and operating costs. Minimized or eliminated downtime. Increased IT productivity.

3. Challenges

   • Depleted resources performance and availability sufferLack of application awareness. OS virtualization doesn’t virtualize the applicationUnused virtualization features the network limits implementation

4. Types

   • Type 1
     • A Type 1 hypervisor is also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines
   • Type 2
     • A Type 2 hypervisor, also called a hosted hypervisor, is a virtual machine (VM) manager that is installed as a software application on an existing operating system (OS).

5. Drawbacks

   • It can have a high cost of implementation. It still has limitations.It creates a security risk.

6. Cloud Computing in Virtualization

   • In the context of cloud computing, virtualization is a technique that makes a virtual ecosystem of storage devices and the server OS. In that case, virtualization enables users to use various machines that share one particular physical instance of any resource.
