基于虚拟化技术的双活数据中心方案设计

Scheme design of double active data center based on virtualization technology

介绍了基于虚拟化技术的双活数据中心方案设计。首先描述了数据中心的总体架构,然后从网络层面、应用层面、数据库层面、存储层面描述了如何实现双活设计,最后总结了实现双活设计的难点,并展望了双活数据中心发展的方向。方案实现了两个中心并行运行,一个中心断了,另一个中心正常运行,用户应用不受影响,避免了备中心长期处于闲置状态的情况,提高了资源利用率,并提供了双倍的服务能力。

The text introduced the design of active-active data center based on virtualization technology. Firstly it described the overall architecture of the data center. Then it described how to realize the active-active design on the network level,the application level,the database level and the storage level. Finally,it summarized the difficulty to achieve the active-active design and looked forward to the direction of the active-active data center development. It realized two centers running at the same time. Once a center was broken,then another center was in normal operation. The application was not affected. It avoided the situation when a center was idle in a long period,improved resource utilization ratio,and provided a double service capacity.
