Database management in utility data centers

企业正在改变他们部署软件应用程序的方式。基于竖井的部署正在让位于基于共享的集中式计算资源池的部署，这些资源池在所谓的公用事业数据中心管理。在竖井部署中，相关应用程序堆栈(例如Web服务器以及底层应用程序服务器和数据库管理系统)部署在具有专用行政和管理功能的专用计算资源上。相比之下，公用事业数据中心整合了计算资源，允许在多个应用堆栈之间共享这些资源，并为整个企业的利益进行管理。公用事业数据中心模式的一个优势是通过提高资源利用率来节省成本。围绕资源整合的技术正变得越来越成熟，使这些数据中心的灵活管理成为现实。

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.
