Proficient Allocation of Resources and Time Arrangement

Abstract

The cloud architecture is usually composed of several XaaS layers—including Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). The previous  work studies efficient  resource  allocation  to  optimize  objectives  ofcloud  users,  IaaS  provider  and  SaaS  provider  in  cloud computing. This work proposes the composition of different layers in the cloud, such as IaaS and SaaS, and its joint  optimization  for  efficient  resource  allocation.  The  efficient  resource  allocation  optimization  problem  is conducted  by  sub  problems.  Our  proposed  work  mainly  concentrates  on  efficient  scheduling  and  resource allocation  to  optimize  objectives  of  cloud  users,  IaaS  provider  and  SaaS  provider.  Early  task  scheduling algorithms are focused on minimizing make span, without mechanisms to reduce the monetary cost incurred in the setting of clouds. Acost-efficient task-scheduling algorithm using two heuristic strategies. The first strategy dynamically maps tasks to the most cost-efficient VMs based on the concept of Pareto dominance.
