Load balancing in cloud environment with switching mechanism and token-based algorithm

Abstract

Cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud environment comprises of abundant nodes with distributed computing resources in different geographic locations. The main aim is to maintain all the data centres to be available and also to distribute the load uniformly to all the data centres. Load balancing with switching mechanism contains two different algorithms in which, one algorithm is used to distribute the jobs in idle state divisions and another, token-based load balancing (TLB) algorithm is used to distribute the jobs in the normal state divisions. The basic demand of each user is to complete requested jobs in the short time, so the public cloud need a mechanism, which can complete the jobs of all users with reasonable response time. The proposed work chooses different strategies for different load conditions. Whenever the server is overloaded, the TLB algorithm migrates the job to the available data centre (DC) either within a cloud division or to the data centre in other cloud division.
