Survey on fault tolerant — Load balancing algorithmsin cloud computing

Abstract

The cloud computing is an emerging paradigm over the internet which provides applications and services based on the concept of abstraction and virtualization for a fraction of the cost. The number of cloud user increases day by day to utilize the available resources. Most of the cloud applications are run at remote nodes where many clients may request for the server at a time. This causes overloading in server which results in fault. Load balancing is the networking technique that distributes load to the nodes to optimize resource utilization, throughput, response time and overload. The need of load balancing increases with increase in the demand for computing resources. Fault-tolerance is the ability of system to continue to work even in the presence of fault. This is a critical issue to be addressed to ensure reliability and availability in cloud computing. By effectively balancing the incoming load, fault tolerance can be achieved in cloud. This paper aims to compare the efficient load balancing algorithms that are fault tolerant.
