為什麼選擇 DDM

相比傳統(tǒng)單機(jī)資料庫(kù)，華為雲分布式資料庫(kù)中間件DDM專(zhuān)註解決海量存儲(chǔ)、高並發(fā)吞吐、大表瓶頸以及複雜計(jì)算效率等資料庫(kù)瓶頸問(wèn)題

穩(wěn)定可靠、高度可擴展的關(guān)係型分布式資料庫(kù)

穩(wěn)定可靠：DDM將數(shù)據(jù)分散到N個(gè)數(shù)據(jù)節(jié)點(diǎn)（RDS for MySQL）存儲(chǔ)，每個(gè)數(shù)據(jù)節(jié)點(diǎn)都能承擔(dān)合適的數(shù)據(jù)存儲(chǔ)和計(jì)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(zhǎng)
線(xiàn)性擴展：DDM採用存儲(chǔ)計(jì)算分離架構(gòu)，支持計(jì)算層、存儲(chǔ)層在線(xiàn)增加資源，存儲(chǔ)層可以通過(guò)增加分片數(shù)或者數(shù)據(jù)節(jié)點(diǎn)數(shù)來(lái)解決單表數(shù)據(jù)量過(guò)多或者容量瓶頸等問(wèn)題，打消客戶(hù)在業(yè)務(wù)快速發(fā)展過(guò)程中針對(duì)資料庫(kù)擴展性產(chǎn)生的運(yùn)維壓力

全方位保證資料庫(kù)安全和用戶(hù)隱私

身份認(rèn)證：提供用戶(hù)身份認(rèn)證、權(quán)限分配功能，精細(xì)控制資源的訪(fǎng)問(wèn)權(quán)限
安全訪(fǎng)問(wèn)：提供網(wǎng)絡(luò)安全訪(fǎng)問(wèn)控制，可設(shè)置安全組進(jìn)出規(guī)則，控制可連接資料庫(kù)的網(wǎng)絡(luò)範圍
審計(jì)日誌：關(guān)鍵操作對(duì)接雲審計(jì)，輕鬆追溯歷史事件
故障恢復：AZ級(jí)高可用，故障秒級(jí)恢復

輕鬆接入，持續(xù)可運(yùn)維

語法兼容：支持MySQL官方驅動(dòng)，無(wú)需使用定製化SDK，高度兼容MySQL語法
簡(jiǎn)單易用：輕鬆數(shù)據(jù)導(dǎo)入，資料庫(kù)上雲。業(yè)務(wù)零代碼改動(dòng)，實(shí)現(xiàn)讀寫(xiě)分離
快速部署：在線(xiàn)快速部署實(shí)例，節(jié)省採購(gòu)、部署、配置等自建資料庫(kù)工作，幫助業(yè)務(wù)快速上線(xiàn)
輕鬆運(yùn)維：監(jiān)控告警、備份恢復、日誌管理，完善的運(yùn)維和技術(shù)支持，減輕運(yùn)維負(fù)擔(dān)，降低企業(yè)成本

網(wǎng)際網(wǎng)路應(yīng)用

電商、金融、遊戲、社交等網(wǎng)際網(wǎng)路應(yīng)用，業(yè)務(wù)發(fā)展隨市場(chǎng)驅動(dòng)，流量洪峰和數(shù)據(jù)量迅速增長(zhǎng)導(dǎo)致性能瓶頸。DDM大幅可提升資料庫(kù)處理效率，加快系統(tǒng)訪(fǎng)問(wèn)速度

優(yōu)勢(shì)

線(xiàn)性水平擴展

自動(dòng)完成水平拆分，線(xiàn)性提升應(yīng)用處理能力

分片變更

可增加任意分片數(shù)或者數(shù)據(jù)節(jié)點(diǎn)（RDS for MySQL）數(shù)，自動(dòng)實(shí)現(xiàn)數(shù)據(jù)重分布（Rebalance）

高讀寫(xiě)性能

PB級(jí)數(shù)據(jù)量訪(fǎng)問(wèn)；十倍於單機(jī)資料庫(kù)連接數(shù)；百萬(wàn)級(jí)高並發(fā)
