What is Elasticity

Chapter 22
Handbook of Research on Architectural Trends in Service-Driven Computing
Ability to dynamically deploy and scale systems resources based on need in real time. This provides an illusion of infinite amount of resources to consumers allowing the consumer to purchase only what they need.

Abstract
Cloud computing is synonymous with outsourced data center management and agile solution architecture that improves the scalability for delivery of services for enterprises. It has the capability to revolutionize how data is delivered from commodity to Information Technology as a service. At its core, Cloud computing is a new approach to distributed computing and shared pooling of IT infrastructure linked together to offer centralized IT services on demand. Companies that provide Cloud computing services manage multiple virtualized computation systems that allow for dynamic on-demand provisioning of IT delivery as services. This chapter presents a study of the factors that influence the adoption of Cloud computing in enterprises based on managements' perception of security, cost-effectiveness, and IT compliance. The results of a linear regression analysis testing are presented, which indicate that managers' perceptions of cost-effectiveness and IT compliance are more significantly correlated to the enterprise adoption of Cloud computing than security.

Infrastructural Development: An Engine of Growth – An Empirical Study in SAARC Countries
Elasticity is a mathematical concept. It can be applied to functional relationship. Suppose we have a function where is the independent variable and is the dependent variable. If changes by 1% the resulting percentage change in is called elasticity of with respect to . Thus the ratio of percentage change in to percentage change in represents the elasticity of with respect to . Elasticity of this function is defined as . The formula for elasticity can also be expressed in terms of logarithmic differentiation as .
