Active thaj chaw - rov ua dua yog ib Azure SQL Database feature uas tso cai rau koj los tsim cov ntaub ntawv thib ob uas nyeem tau ntawm ib tus neeg databases ntawm SQL Database neeg rau zaub mov hauv tib lossis sib txawv cov ntaub ntawv chaw (cheeb tsam). SQL Database kuj txhawb pab pawg neeg tsis ua haujlwm. Yog xav paub ntxiv, saib siv pab pawg auto-failover.
Tsis tas li ntawd, kuv yuav ua li cas thiaj li pab tau qhov kev hloov pauv hauv Geo hauv Azure?
Kev piav qhia
- Nkag mus rau Azure Portal.
- Nyob rau sab laug ntawm lub vijtsam xaiv BROWSE thiab tom qab ntawd xaiv SQL Databases.
- Nkag mus rau koj cov ntaub ntawv database, xaiv Geo Replication daim ntawv qhia thiab nyem Configure Geo-Replication.
- Nkag mus rau Geo-Replication hniav.
- Coj mus rhaub rau Tsim Secondary hniav.
Kuj Paub, pes tsawg replicas geo replication pub rau nrog Azure SQL Database? Raws li twb tau hais lawm, Active Geo - Replication yog ib tug ua lag luam Continuity feature rau SQL Database uas tso cai qhov sib ntxiv ntawm mus txog plaub theem nrab cov khoom qub ntawm koj database kis tau rau hauv cheeb tsam uas koj xaiv.
Ib sab saum toj no, puas yog Geo replication enabled los ntawm lub neej ntawd hauv Azure?
Kev piav qhia: Hauv Windows Azure khaws cia, Geo Redundant Cia (GRS) yog qhov ua ntej kev xaiv rau redundancy. Kev lag luam yog luam tawm mus rau 3 nodes nyob rau hauv thawj cheeb tsam xaiv rau tsim tus account cia. Geo Redundant Cia (GRS) yog qhib thaum tsim tus account cia.
Geo redundancy ua haujlwm li cas?
Geo - redundancy yog hais txog kev sib cais ntawm lub cev ntawm cov chaw zov me nyuam uas nthuav dav ntau yam thaj chaw qhov chaw. Yog vim li cas tom qab tsim ib tug loj, thaj chaw network, yog tias nws muab kev tiv thaiv tiv thaiv kev puas tsuaj ntuj tsim, kev puas tsuaj loj lossis teeb meem uas ua rau muaj kev cuam tshuam hauv lub network.
