Cloud computing is an evolving paradigm which offers great computational power to the organizations which require processing of large amount of data. The growth of high speed networks have led to the rise in the concurrent transactions a day. Cloud computing is architecture for providing computing service via the internet using the central remote servers to maintain data and applications. We are in unprecedented times in view of the recent outbreak and far-reaching spread of the Corona virus, which leads us to respond to new work settings, including a remote work environment and virtualization. With increase in computer and Mobile user’s, data storage has become a priority in all fields. Cloud computing is the on-demand availability of system resources, especially data storage and computing power without direct active management by the user. It allows access to a pool of shared resources namely networks, storage, servers, services and applications, without physically acquiring them. Users can store, access, and share any amount of information in cloud. The data is secured and can access anytime and from anywhere. This paper presents the basics of cloud computing, it’s types, characteristics, services and applications in various sectors.

Cloud computing, architecture, deployment models, service models, pay-per-use, Resource Pooling.
