很长一段时间内,构造高可用系统通常需要使用集群技术,集群运算是一种组成及管理成本都比较高的体系架构,能否构造一种成本较低同时具备高可用特征及易于管理的体系架构成为建设应用系统的重要课题。最新一期的新华社多媒体数据库应用升级项目中,项目组就将NAS技术应用到了多媒体数据库稿件入库平台上,很好地解决了稿件入库集群服务器的负载均衡、数据同步和备份切换等问题。
For a long time, the construction of highly available systems usually requires the use of clustering technology. Cluster computing is an architecture with relatively high composition and management costs. Can a cost-effective system with highly available features and easy management be constructed? Architecture constitutes an important issue for the construction of application systems. The latest issue of Xinhua News Agency multimedia database application upgrade project, the project team will NAS technology applied to the multimedia database manuscript storage platform, a good solution to the manuscript into the cluster server load balancing, data synchronization and backup switching and other issues .
