Also, server virtualization is adapted for the fast provisioning of new VMs through the use of templates, which enables providers to offer elasticity services for application developers [12].
The optimal bonuses are expressed in terms of demand elasticities, service technology, and provider characteristics.
In order to illustrate our approach, we propose a use case that specializes our autonomic infrastructure to ensure the elasticity of Service-based Business Processes (SBPs).
By combining the performance of dedicated, single-tenant servers with the elasticity, self-service and pay-as-you go pricing associated with virtual public cloud, bare-metal cloud servers are gaining popularity with Internet-centric customers that need consistently high performance and cost-efficiency for distributed, large-scale application environments.
Pooling and sharing of resources, broad network access, rapid elasticity, on-demand service provisioning (with a strong self-service element), offering of measured service, supporting (although not necessitating) multi-tenancy, are some of the features that characterise cloud computing.
Based upon NIST's definition of cloud computing, its five essential characteristics (self-service, broad network access, resource pooling, rapid elasticity and measured service) [ 2] were checked for being mentioned by the authors.
The essential characteristics are on-demand self-service, location-independent resource pooling, broad network access, rapid resource elasticity, and measured service.
This is because of the rise in marketing and customer service elasticity of demand, the marketing and customer service expenditures are increasing in response to customers' requests as well (Fig. 11).
In our opinion, an application which really enhances its provision by means of cloud computing should explicitly describe the cloud-specific characteristics of their application following the NIST definitions, such as rapid elasticity or measured service where a pay-per-use model supersedes upfront investments.
We use the unusually rich data from the 1991 to 2006 Chinese Health and Nutrition Surveys to estimate that in China's renewed market phase the permanent income elasticity of housing services demand in China is.70 and the elasticity of housing services demand with respect to the price of space is −.64.
