通过冗余副本自动故障切换,并且故障恢复后进行一次全量同步,保持数据一致性。 数据复制 数据持久化 业务系统日常运行中可能出现一些小概率的异常事件。部分可靠性要求非常高的业务系统,除了要求缓存实例高可用,还要求缓存数据安全、可恢复,甚至永久保存,以便在缓存实例发生异常后能够使用备份数据进行恢复,保障业务正常运行。
通的。 如果弹性云服务器与Memcached实例不在相同VPC中,可以通过建立VPC对等连接方式连通网络,具体请参考常见问题:缓存实例是否支持跨VPC访问? 如果弹性云服务器与Memcached实例配置了不同的安全组,可以通过设置安全组规则连通网络,具体请参考常见问题:如何选择和配置安全组?
