Design Of Cloud Data Center Based On Virtualization And Implement Of Load Balancing

In the context of the rapid development of science and technology today, theInternet has been integrated into every corner of our lives, a lot of data has emergedonline, at the same time a large number of data centers have sprung up, the traditionaldata center model is not perfect to meet the storage and processing problems ofmodern large amounts of data, a new concept urgent need to introduce to improve thesituation, new technology concepts needed to be introduced to improve the situation.The concept of cloud computing was born in this environment, the high resourceutilization, reasonable energy consumption, good balance system and stable runningprotection of cloud computing, provide a good solution to the thorny problem of thetraditional data center, the cloud-based data center will become the main trend of thedevelopment of the next-generation data center.This paper departure from the needs of small and medium-sized enterprisesinformation services, to focus on considering many factors such as virtualization andresource allocation in cloud computing, massive data processing, and data centerbuild mode, giving out a design of cloud data center based on virtualization, and aImplement of load balancer in non-relational database cluster.The main work of this paper is as follows:First, analysis the status quo of today’s data center and the problems it faced, bystudying the key technology: virtualization, mass data storage, resource scheduling, ofcloud computing, combined with the advantages of the traditional data center, focuson the establishment of the data center, system load conditions, task concurrent access.Given a framework of cloud data center based on virtualization.Second, according to the existing non-relational database prototype, extended thedatabase to a cluster, design corresponding management node and database node, andgiven communication message sequence that between nodes. Given detail functionalpartitioning of the management node, the design and solution of the important modules and strategy.Third, by using VMWare virtualization software make computer’s physicalresources to virtual, given the construction and loaded of virtual machine anddedicated disk, implementation of building a resource pool, simulation provides acloud platform in the laboratory environment.Forth, given the design of the load balancer in the database cluster that said above,research on efficient dynamic load balancing algorithm on the basis of this, given themethod of design and implementation, test analysis of the performance of thealgorithm by experimental.
