A DETAILED STUDY OF VARIOUS CHALLENGES IN CLOUD COMPUTING

Cloud computing is internet based ("cloud") development and use of computer technology ("computing"). Because of accessibility of diverse services and extensibility for vast areas of computing processes, individual users and organizations convey their data and services to the cloud storage server. The point of demarcation between the responsibilities of the provider and those of the user is denoted by the cloud symbol. The network infrastructure as well as the servers are covered in cloud computing since they lie within its boundary. A set of IT services provided to a customer over a network on lease with the ability to scale up or down their service requirements is called cloud computing. Cloud computing services are usually delivered by a third-party provider who owns the infrastructure. The security issues and challenges associated with cloud computing are making organizations hesitate in accepting it despite potential gains achieved. Nevertheless, of its advantages, the transformation of local computing to remote computing has brought up many security issues and challenges for both the users and providers. One of the major issues that hamper the growth of cloud is security. This paper focuses on existing issues in cloud computing such as security, privacy, reliability and so on.
