Virtual Machine Load balancing in Cloud Environment: A Review

With the onset of tremendous use of Cloud Computing technologies across the globe, there has been an extensive increase in the number of users of these technologies in a very short span of time. Due to this fact, the load of balancing the cloud services and products have been on a steep increase along with its research opportunities. Cloud id generally dependent on dominant datacenters that provide services to a large number of users. So to achieve reliability and to boost the enactment of the cloud, proper load balancing should be in place and this is done by featuring a load balancer with the datacenter. To provide cloud service effectively, many algorithms were proposed for sending user’s request to cloud resources. A set of several load balancing algorithms has been reviewed in this paper along with the implementation details using Infrastructure as a framework and a summary of these techniques has been discussed extensively. The paper also describes the implementation of a virtual environment for cloud computing for a WAM Load Balancing Algorithm using several tools like CloudSim. This algorithm is used with the datacenter to balance the load request effectively assigning a weight between the available virtual machines. This improves the performance by balancing the data processing time against the response time.
