It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you. It provides an easy way to provide configurable resources by taking it from a shared pool. The pool consists of networks, servers, storage, applications and services. What is the difference between scalability and elasticity? Scalability is a characteristic of cloud computing through which increasing workload can be handled by increasing in proportion the amount of resource capacity. It allows the architecture to provide on demand resources if the requirement is being raised by the traffic. Whereas, elasticity is being one of the characteristic provide the concept of commissioning and decommissioning of large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources. What are the

 Active Directory enables single sign on to access resources on the network such as desktops, shared files, printers etc. Active Directory provides advanced security for the entire network and network resources.  Active Directory is more scalable and flexible for administration. Functional levels help the coexistence of Active Directory versions such as, Windows NT, Windows 2000 Server, Windows Server 2003 and Windows Server 2008. The functional level of a domain or forest controls which advanced features are available in the domain or forest. Although lowest functional levels help to coexist with legacy Active Directory, it will disable some of the new features of Active Directory. But if you are setting up a new Active Directory environment with latest version of Windows Server and AD, you can set to the highest functional level, thus all the new AD functionality will be enabled. Windows Server 2003 Domain Functional Levels: Windows 2000 mixed (Default), Windows 2000 native, Wind
