Issues and Challenges of Data Transaction Management in Cloud Environment

Cloud Computing is one of the most important areas in the current IT industries. It provides different type of services (SaaS, PaaS, and IaaS) depending on the customers’ requirements. Instead of owning, installing and maintaining software in IT industries can use Cloud computing. In this paper, needs of ACID properties for cloud databases, advantages and limitations of cloud databases are discussed. It also portrait the major issues and challenges of Database Architectures and Data Transaction Management in Cloud Environment. There are different procedures used to handle the data, but each one of them has its own limitations in cloud environment. Finally this paper provides an exhaustive study on Transaction Processing System, Cloud DataBase as a Service (DBaaS), Cloud RDBMS and Cloud data storages in order to design a novel architecture for cloud databases with the support of traditional ACID properties.
