Selective Testing For Cloud Computing

Abstract

Cloud computing is the way in which a user acquire services such as software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS). Users get services by deploying their data and application on remotely servers. They pay only for the time the resources are acquired and based on computing resource running. They do not need to install and upgrade any software and hardware. Due to these benefits, organizations are willing to move their data into the cloud and minimize their overhead. In cloud computing, virtual machines play a vital role in providing services and deploying application for large number of users. Users should have information about a cloud performance before subscribing data and applications. The researcher overcomes problems by selective testing for cloud computing. The objective of this study is to give selective testing and to investigate cloud performance status and capacity of servers. Finding the parameters helps us to measure the actual performance of a cloud computing on some specific data and application. These parameters will help users, enterprises, developers and IT specialists to measure cloud performance based on their requirements and needs. In order to fulfill the objective of this study, an experiment and implementation had been done on lab test environment. Java programming language has been used for changing the algorithm as one method. Local cloud has been deployed using open source cloud which is known as openstack to conduct real test and Applications Manager tool used for testing services of Amazon EC2. In the experiment, performance parameters (Throughput, response time and latency) including cost were tested and analyzed.
