為什么選擇 DDM

相比傳統(tǒng)單機數(shù)據(jù)庫，華為云分布式數(shù)據(jù)庫中間件DDM專注解決海量存儲、高并發(fā)吞吐、大表瓶頸以及復(fù)雜計算效率等數(shù)據(jù)庫瓶頸問題

穩(wěn)定可靠、高度可擴展的關(guān)系型分布式數(shù)據(jù)庫

穩(wěn)定可靠：DDM將數(shù)據(jù)分散到N個數(shù)據(jù)節(jié)點（RDS for MySQL）存儲，每個數(shù)據(jù)節(jié)點都能承擔(dān)合適的數(shù)據(jù)存儲和計算負(fù)載，將故障影響面降至1/N，達(dá)到穩(wěn)定可靠的效果，支撐業(yè)務(wù)爆發(fā)式增長
線性擴展：DDM采用存儲計算分離架構(gòu)，支持計算層、存儲層在線增加資源，存儲層可以通過增加分片數(shù)或者數(shù)據(jù)節(jié)點數(shù)來解決單表數(shù)據(jù)量過多或者容量瓶頸等問題，打消客戶在業(yè)務(wù)快速發(fā)展過程中針對數(shù)據(jù)庫擴展性產(chǎn)生的運維壓力

全方位保證數(shù)據(jù)庫安全和用戶隱私

身份認(rèn)證：提供用戶身份認(rèn)證、權(quán)限分配功能，精細(xì)控制資源的訪問權(quán)限
安全訪問：提供網(wǎng)絡(luò)安全訪問控制，可設(shè)置安全組進出規(guī)則，控制可連接數(shù)據(jù)庫的網(wǎng)絡(luò)范圍
審計日志：關(guān)鍵操作對接云審計，輕松追溯歷史事件
故障恢復(fù)：AZ級高可用，故障秒級恢復(fù)
