Development and Usage of Software as a Service for a Cloud and Non-Cloud Based Environment- An Empirical Study

Abstract

Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. The computer applications nowadays are becoming more and more complex; there is an ever increasing demand for computing resources. As this demand has risen, the concepts of cloud computing and grid computing have found many followers with more and more companies looking to outsource computing needs to a third party vendor. However, this growing dependence on third party providers is causing large corporations as well as research groups to look for alternative models that can support the increased demand for computing resources. The concerns of reliability, privacy, efficiency at the expense of resilience and environmental sustainability are at the forefront of such research. For application providers, cloud computing has the advantage that it reduces the administrative effort required to satisfy processing and storage requirements. However, to simplify the task of building scalable applications, some of the cloud computing platforms impose constraints on the application architecture, its implementation and tools that may be used in development. The changing scenario in education has given rise to need of technology in education. Information Technology has played a major part in improving the learning outcomes of individuals. Technologies like cloud computing has not only reduced the burden of economy as well as resources required. This paper has shown the different aspects of using cloud and non-cloud environment.
