Thoughts on Cloud Computing Now and In The Future

International Journal of Innovative Research in Computer Science & Technology, 2021

Cloud computing is a burgeoning technology that has ushered in a new era by allowing for a logical computational approach. Over a concept that delivers on-demand services online, it has revolutionized the mechanics of IT consumption. Unlike traditional hosting, cloud services are priced for per basis and may rise or decline in response to feedback. Such services are typically totally managed by cloud service providers and demand only a home computer with an internet connection from users. This model has got the attention of researchers, capitalists, and operators in latest days, with most of them presenting a range of cloud computing, frameworks, and ideas, resulting in a diversity of definitions, requirements, and models. Despite the excitement and development in the field, questions around privacy and security, service discovery partnerships, sharing of resources, and pricing have created additional worries about the model's genuine merits. Deny the reality that infrastructure...

The fast developing era of computer technology has gone through the spectacular advances in computing storage, processing capabilities and networking technology, which have allowed the users to generate, process, and share huge volume of information with high reliability and efficiency. The need for processing and distribution of huge data leads to the development of cloud computing, which enables convenient, limitless, on demand network access to a shared pool of computing resources placed at different places. Numerous users and research organizations are now applying cloud-computing concepts for easy and efficient solutions to their computing and data sharing needs. This chapter provides the detailed discussions on the architecture of cloud computing, its advantages, and various potential applications in the field of Information Technology (IT), agriculture, library and education.

Cloud computing is gaining ground in the global ICT market and day by day a significant number of Small and Medium Enterprises (SMEs) are adopting cloud services with sole purpose to improve their business environment and become more efficient, competitive and productive. Migrating a business IT infrastructure to the cloud offers reduction on server and storage costs, software maintenance expenditures, network and energy expenses as well as costs associated with disaster recovery. Since the cloud computing model works on a “pay-as-you-go” basis, it provides the option to pay for what is used. Thus, its adoption can offer slow start-up or expansion costs, creating an environment for rapid innovation and development. Into that context, this article presents the Greek side of cloud evolution through two representative case studies, the migration of an IT system of a Greek industry, from an in-house data center to Google Cloud and a study of the “in-house” IT infrastructure of the Natio...

Cloud computing is the computing that provides virtualized IT resources as a service by using Internet technology. In cloud computing, a customer lends IT resources as needed, uses them, get a support of real-time scalability according to service load, and pays as he/she goes. Cloud computing is becoming an adoptable technology for many of the organizations with its dynamic scalability and usage of virtualized resources as a service through the Internet. Cloud computing uses the Internet and central remote servers to maintain data and applications. As know that at present the e- ccommercee services opportunity to utilize pay-as-you-go resources together with their own and shared resource in the fields of IT. In this paper shows that the cloud computing plays an important role in the fields of Information Technology services and its applications and it is helpful to provide the data to the customer. The results show that the comparison of cloud services and normal services of Informa...
