Economics and Elasticity Challenges of Deploying Application on Cloud

The disclosure of the web applications has significantly improved the variability of its workload patterns and volumes as the number of users/customers frequently increases and shrinks at different rates and times. The web application features have gradually required the need for flexible however inexpensive computing infrastructure to accommodate variable workload. The on-demand and per-user cloud computing model, precisely that of Cloud Infrastructure Service Offerings (CISOs), had quickly evolved and developed by majority of the hardware and software companies with the promise of provisioning utility like computing resources at enormous economics of scale. However, deploying applications on cloud infrastructure does not lead to accomplishing desired economics and elasticity gains, and some challenges block the way for realizing its real benefits. These challenges are due to multiple differences between CISOs and application’s requirements and characteristics. Here, detailed analysis and discussion of the economics and elasticity challenges of applications to be e deployed and operate on cloud infrastructure. Also, contains analysis of different aspects of CISOs, modelling and measuring economics and elasticity, application workload patterns and its impact on achieving elasticity and economics, economic-driven elasticity decision and policies, SLA-driven monitoring and elasticity of cloud-based applications. These are supporting with motivating scenarios for cloud-based applications. Here deference perspective analysis that help to cloud customer and potential application’s owners to understand, analyse, and evaluate important economics and elasticity capabilities of different CISOs and its adaptably for meeting their application’s requirements.
