Survival study on resource utilization and task scheduling in cloud

Abstract

Cloud computing provides different services to the registered users because users do not need to invest in computing infrastructure. Cloud infrastructure achieved enhanced resource service using various techniques depending on user requirements. Users have the potentiality in accessing several services provided by Cloud Infrastructure via the Internet. Cloud infrastructural resource scheduling allocated the arrival and service time for every resource with the cloud service provider. Cloud infrastructural resource optimization is the method of planning one or more resources for reducing the overall cost while attaining higher performance under given constraints. Several methods were designed for resource allocation, task scheduling in cloud infrastructure. But, some challenges like load instability and low quality of service were experienced by existing techniques due to different user requests in a heterogeneous environment. To overcome such issues, various resource allocations and task scheduling are reviewed.
