Challenges Management and Opportunities of Cloud DBA

This paper discuss the challenges and opportunities of Cloud computing DBA, beginning with building the database in the cloud by comparing between available architectures and choose the suitable one for the cloud. also we compare between traditional relational database (RDBMS) and NoSQL Database and discuss the most important parameters which is important for cloud DBA. we discuss the limitations and opportunities of deploying data management issues on these emerging cloud computing platforms (e.g., Amazon Web Services). We speculate that large scale data analysis tasks, decision support systems, and application specific data marts are more likely to take advantage of cloud computing platforms than operational, transactional database systems. We thus conclude the need for a new database administration system designed especially for cloud computing environments.本文探讨了云计算数据库管理员（Database Administrator，DBA）所面临的挑战与发展机遇。开篇首先围绕云端数据库构建工作，对比当前可用的各类架构并筛选适配云环境的最优方案；此外，本文还对比了传统关系型数据库（Relational Database Management System，RDBMS）与非关系型数据库（NoSQL Database），并探讨了云计算数据库管理员工作所需考量的核心参数。本文还分析了在Amazon Web Services这类新兴云计算平台上部署数据管理工作所存在的局限与机遇。我们推测，相较于联机事务处理型数据库系统，大规模数据分析任务、决策支持系统以及面向特定应用的数据集市更易于依托云计算平台发挥效能。据此本文得出结论：亟需面向云计算环境量身定制全新的数据库管理系统。
