AUTOMATIC SCALING OF WEB APPLICATIONS FOR CLOUD COMPUTING SERVICES: A REVIEW

Sushil Deshmukh, Sweta Kale

Abstract: Now days there are many web applications can get benefit from automatic scaling property of cloud where the no of resources usage can be scale up and down automatically by cloud service provider. So here present system that provides automatic scaling for web application in cloud environment. So every application instance encapsulated inside virtual machine and model it as the Class Constraint Bin Packing (CCBP) problem. Where each class represents an application and each server is a bin and uses virtualization technology for fault isolation. Now many business customers need good satisfy response services from cloud. So design and develop semi online color set algorithm that achieve good demand satisfaction ratio and as well as when load becomes low it reducing number of server and save energy. Experiment results compare open source implementation of Amazon EC2 demonstrates that system can improve the throughput by 180% over. And system can restore the normal quality of service five times as fast when huge crowd happens. Take supports of green computing to adjusting the placement of application instance adaptively and putting ideal machine into the standby mode.

Keywords: auto scaling, cloud computing, CCBP, green computing, virtualization etc…
