ANALYSIS ON LOAD BALANCING ALGORITHMS IMPLEMENTATION ON CLOUD COMPUTING ENVIRONMENT

Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.Cloud Computing can be considered as a platform for development, maintenance and accessing applications by user by paying for the resources which are only used for certain time. To serve for huge number of requests from different types of users located at different parts of the world on pay-per-usage bases, the process of virtualization has been followed in cloud computing environment. There are so many service providers who are responsible for maintaining the application on cloud environment. The most predominant cloud service providers are Google, Amazon, Microsoft and many others. In order to serve the huge traffic to world these service providers maintain data centers all over the world where the data is stored in bulk and requests are processed [4]. Depending on the number of requests to be processed by a data center, no. of virtual machines is created where on a single CPU different operating systems and their configurations can be run. It gives the illusion to the users that, there are numbers of CPUs are involved for processing the requests. This whole process can be considered as virtualization and it is monitored by the software called as hypervisor. The hypervisor is mainly responsible in creating and maintaining the virtual machines. The requests from all the users are considered as individual request and each of the virtual machines is assigned a request and effort is made to keep them busy for longer time
