Question three. Describe The Major Benefits Of Server Virtualization.

Answer :

It enables reduce prices and saves area as you don’t need to buy extra hardware.
Cuts down on upkeep prices with less physical servers.
It gives accelerated security as the virtual servers are independent of one another.
Business continuity with high availability of your packages as every other server can take over when one fails.
Question four. What Is The Difference Between Hosted Virtualization And Hypervisor-based Virtualization?

Answer :

Hosted virtualization products run the virtualization software program on pinnacle of the host OS, which introduces extra overhead and a longer code execution direction for the digital machines (VMs) that run inside the hosted virtualization environment. In assessment, hypervisor-primarily based merchandise consisting of ESX Server and Hyper-V are designed to run the hypervisor directly on the device hardware.

Question 5. What's The Idea Behind Type 1 And Type 2 Methods Of Virtualization?

Answer :

Type 1-A approach used wherein the virtualization layer runs at once at the host's hardware. The host and guest operating systems run on some other stage above the hypervisor. Examples of the kind 1 hypervisor approach are VMware ESX and Xen based systems.

Type 2-The virtualization layer runs on pinnacle of an current operating gadget and is in effect a hosted application. Examples of a kind 2 hypervisor are Sun's VirtualBox, VMware Server and VMware Workstation.
