Framework for Application Service Behavior Prognostication with Cost-Effective Provisioning In a Utility Cloud
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 3
Abstract
In A Utility Cloud Resources Are Operating On A Utility Basis That Allows Customers To Pay As They Go And Only For The Resources They Will Use At Multiple Granularities For A Specified Level Of Quality Of Service. Cloud Infrastructure Services Or Iaas (Infrastructure–As-A-Service) Delivers The Computer Infrastructure Or We Can Say A Platform Virtualization Environment, As A Service And The Service Is Typically Billed On A Utility Computing Basis And Amount Of Resources Consumed. Generally, This Infrastructure Allocation Is Static And Resources Are Allocated During VM Instantiation. Any Change In Workload Leading To Significant Increase Or Decrease In Resources Is Handled By VM Migration. Hence, Cloud Users Tend To Characterize Their Workloads At A Coarse Grained Level Which Potentially Leads To Over-Allocated VM Resources Or Under-Performing Application. That Means Either User Is Paying More In Case Of Over-Allocation Of Resources Or The Application Is Under-Performed In Case Of Under-Allocation Of Resources. In This Paper, We Present A Framework For Iaas Utility Cloud Where A Prognostication Component Predicts At Run-Time The Expected Demand By Application Which Is Then Used To Modulate Resource Allocation Based On The Predicted Demand. We Derive This Component Based On A Cost Model To Make It More Cost-Effective For Both The Service User And The Service Provider. Confidence Interval For Predicted Workload Is Used To Minimize This Effective Cost.
