1, What is VIRTUALIZATION? Is a technology that we can use to produce virtual representations of networks,servers, storage and other physical machines.It imitates the functions of physical hardware to run multiple virtual machines simultaneously on a single physical machine.
2, SCALABILITY the ability to increase or decrease IT resources as needed to meet changing demand, the ability of an organization (or a system, such as a computer network) to perform well under an increased or expanding workload.
3, AGILITY is the ability to quickly develop, test, and launch applications in a cloud-based environment.
4, HIGH AVAILABILTY is a quality of computing infrastructure that allows it to continue functioning, even when some of its components fail, mostly essential for mission-critical systems that cannot tolerate interruption in service, and any downtime can cause damage or result in financial loss.
5, FAULT TOLERANT is refers to the ability of a system (computer, network, cloud cluster, etc.) to continue operating without interruption when one or more of its components fail or malfunction.
6, GLOBAL REACH This simply means that the Cloud does not constraint to one locality, it goes beyond a particular geographical boundaries, it enables organizations to establish a global footprint without the constraints of physical infrastructure.
7, WHAT IS THE DIFFERENCE BETWEEN ELASTICITY AND SCALABILTY? Elasticity refers to how fast your application can scale up or down based on demand, while scalability refers to how the system can handle much load, Elasticity involves stretching the boundaries of a cloud environment, while scalabilty has to do with building up or down of cloud computing.
