SECURE: DYNAMIC DISTRIBUTED LOAD BALANCING TECHNIQUE IN CLOUD COMPUTING
Main Article Content
Abstract
The increase in demands of information services, cloud computing proves itself to enhance scaling, agility, availability and flexibility. But cloud computing has very critical issues as load balancing, security and fault tolerance. As number of users is increasing day by day, the crucial task of cloud computing is to adjust loads of memory, CPU and network to fulfill demands of all clients. For that a number of static and dynamic load balancing algorithms are proposed. Here we are proposing a load balancing algorithm based on clusters in which cluster are formed on geographical bases. All cloud servers arranged in distributed manner. Each Cloud server have a queue length (for ex. 100) of jobs allocated to it. A server can serve up to 100 requests. As 101 request came cluster apply its load balancing algorithm. Along with Dynamic distributed load balancing algorithm we have proposed a security algorithm to secure data transmission between client and Cloud service provider. According to this security algorithm client initiates a key generation process to generate encryption and decryption key pairs that will be valid for a particular message. Likewise, a number of key pairs generated. Client can use any key pair for any data encryption/decryption which will be stored on Cloud. Also Client have to keep a record of Key Pairs with Password/PIN. This algorithm performs better in terms of Throughput, Overhead, Fault Tolerance, Resource Utilization, Response Time, and Scalability.
