Dynamic and Scalable Architecture for Accessing the Cloud Databases and Securing Cloud Services Using Public Key Infrastructure

Cloud computing, a revolutionary term for the long-dreamed idea of computing as an application. Cloud Computing can provide numerous advantages for real world applications, such as rapid useful resource elasticity, on-demand self-service, usage-based pricing, outsourcing, pervasive network access, etc. In Cloud computing, large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources. The cloud goals to cut fees, and assist the customers focus on their middle business instead of being impeded by means of IT obstacles. Cloud storage, Data as a Service (DaaS) and Database as a service (DBaaS) are the different phrases used for information management within the cloud. Differ on the basis of how data is stored and managed. Cloud storage is a virtual storage that enables users to store documents and objects. Cloud database should support features of cloud computing as well as of traditional databases for wider acceptability. The potential challenges associated with cloud database are scalability, high availability and fault tolerance, data consistency and integrity, confidentiality and many more. This paper proposes a dynamic and scalable architecture for cloud database services and provides complete protection on data security, data privacy and data breaches on cloud computing with the help of Public Key Infrastructure.
