Database in Cloud Computing - Database-as-a Service (DBaas) with its Challenges?

The Cloud computing (CC) has been widely recognized as the next generation’s computing infrastructure [6]. CC offers many advantages by allowing users to use infrastructure like servers, networks, and storages, platforms containing middleware services and operating systems, and softwares for application programs. Cloud computing is an emerging style of IT delivery that intends to make the Internet the ultimate home of all computing resources. Cloud computing has emerged as a popular model in computing world to support processing large volumetric data using clusters of commodity computers. The delivery of Services by cloud Service Providers in terms of DBase is important as the cloud environment gives access to centralized shared hardware, software and other information. This paper introduces a new transactional “database-as-a-service” (DBaaS) called Database/Relational Cloud. A DBaaS promises to move much of the operational burden of provisioning, configuration, scaling, performance tuning, backup, privacy, and access control from the database users to the service operator, offering lower overall costs to users. Database as a service has several major issues and concerns, such as data Scalability, Elasticity, Availability, security, expectations, etc, issues. Proposed solutions include risk management, better contractual agreements, database encryption, and authenticity techniques. By bettering these situation the DBaas service in cloud computing is effective to manage today’s vast growing datasets.
