Database management in utility data centers

点击翻译按钮获取中文摘要

Enterprises are changing the way that they deploy software applications. Silo-based deployments are giving way to deployments based on shared, centralized pools of computing resources managed in so-called utility data centers. In silo deployments, a stack of related applications, such as a web server together with an underlying application server and database management system, is deployed on dedicated computing resources, with dedicated administrative and management functions. In contrast, the utility data center consolidates computing resources and allows them to be shared among multiple application stacks and managed for the benefit of the enterprise as a whole. One advantage of the utility data center model is cost savings resulting from increased utilization of resources. The technologies surrounding resource consolidation are becoming more mature, making flexible management of these data centers a reality.
