Question

How would you describe virtualization? What role does virtualization play in a cloud computing platform? Under what circumstances would you recommend a cloud platform over Virtualbox?

Answer 1

below circumstances would you recommend a cloud platform:

• No hardware to buy/maintain:if you want a harware but it is very costly so you can use cloud platform it will provide that service by taking some money.

• Unlimited instance scaling:

• Unlimited disk scaling

• Dynamic/Elastic scaling

• Pay for what you use

• Resilient and Redundan

virtualization:

Virtualization is the "creation of a virtual (rather than actual) version of something, such as a server, a desktop, a storage device, an operating system or network resources.

->Virtualization describes a technology in which an application, guest operating system or data storage is abstracted away from the true underlying hardware or software.

->Virtualization software makes it possible to run multiple operating systems and multiple applications on the same server at the same time.

Virtualization can be classiefied in to below types:

1. Hardware Virtualization.
2. Operating system Virtualization.
3. Server Virtualization.
4. Storage Virtualization.

role of virtualization in a cloud computing platform:

Virtualization plays a very important role in the cloud computing.

->Generally in cloud computing the users are shared a data present in the clouds.for example applications..but now a days users can share total infrastructure by useing virtualization.

->using virtualization to run multiple applications on each server instead of one, increasing the utilization rate of every server and, thus, so while reducing the number of servers they need to buy.

->While the main benefit of virtualization is cost-effectiveness.

->irtualization enables agencies to operate a more efficient infrastructure by replacing what had been multiple hardware servers with “virtual” or software versions of those servers that run on a single machine.

-> it is the enabling technology allowing the creation of an intelligent abstraction layer which hides the complexity of underlying hardware or software.

->Virtualizing the storage and incorporating the intelligence for provisioning and protection at the virtualization layer enables companies to use any storage they want, and not be locked into any individual vendor. Storage virtualization makes storage a commodity.
