Jasleen Kaur, Anupma Sehrawat · 2014
Cloud computing is a type of computing that is based on the internet. It provides various hosting and delivering services over the Internet. It provides the computational resources (Server, Storage, OS and Network) to user as service, based on the demand of user. Cloud computing has gained its popularity by providing cheap and easy access to IT (Information Technology). However, despite the fact that demand for cloud based resources is increasing day by day but on the other side security is regarded as a serious issue on which work has to be done. In this paper, we present a survey of cloud computing, highlighting its key concepts, architectural principles, deployment models, service models, benefits as well as security issues related to cloud data. This paper also discusses the related work done regarding security such as Playfair cipher, Proxy reencryption and Railfence technique. The aim of this paper is to provide a better understanding of the cloud computing and to identify important research directions in this field.
