A STUDY OF RECENT ISSUES IN CLOUD COMPUTING TECHNIQUES

Cloud computing plays a vital role in reducing the cost of hardware, software, infrastructure, platform, and other network items. An example of such cost saving in a typical organisation is, reduction of about 30% operational cost in online services by using cloud computing. Hence, a pay per use model can be adopted for deriving cost efficiency. This study presents an overview of a distributed system, cloud computing, virtualization and zookeeper. However, there have been various issues in cloud computing like data security, network security, data locality, data integrity, data segregation, authentication, authorization, access control, availability and backup. We conclude this paper with the challenges associated with cloud-based security, resource constraints, governance, and performance.
