摘要
SmartDNS技术(BIND9)及Eginx反向代理技术实现对不同地区用户甄选地理位置最近的数据中心,以降低因物理距离导致的数据传输时延(线路时延)。为了备份数据特意设立了专门容灾区,保证生产中心的数据一旦出现意外性损毁,可立即使用容灾中心的备份集群数据库进行数据恢复。建设双活数据中心达到应用级容灾标准,提升关键业务连续性及利用率;建设同城及异地数据级灾备数据中心保证数据安全性。
Smart DNS technology (BIND 9) and Eginx reverse proxy technology are used to select the nearest data center for users in different regions to reduce the data transmission delay (line delay) caused by physical distance.At the same time,in order to backup the data,a special disaster area has been set up to ensure that once the data of the production center is damaged by accident,the backup cluster database of the disaster recovery center can be immediately used for data recovery.Double-live data center shall be built to meet the application-level disaster recovery standard and improve the continuity and utilization rate of key businesses;local and remote data level disaster recovery data center shall be built to ensure data security.
