Database Management Challenges in Cloud Environment

Abstract

Abstract-Recently cloud computing is widely used technology in delivering computing resources as a service. There are variety of web-based applications hosted on cloud computing platforms, majority of them are data driven. Therefore database management is now become critical component and challenging task for the DBMS designers and researchers. Scalability, elastic load balancing, pay-per-use pricing and self-managing are the major reasons for the successful cloud database management. This is the review of research published/presented on databases in cloud platform. Various challenges of managing databases in the cloud and various techniques proposed by researchers to face these challenges are presented in this review. It is based on various parameters like database systems in the cloud, scalability and elasticity, autonomy or self-managing database systems and preserving consistency of database in cloud.
