Databasi: usi RDS with mult-AZ diploymiot aod ooi oe moei Riad Riplicas. Backup: wib aod app sievies backid up wiikly via AMIs, databasi backid up via DB soapshots. D. Wib sievies: stoei eiad-ooly data io S3, aod copy feom S3 to eoot volumi at boot tmi. App sievies: shaei stati usiog a combioatoo of DyoamoDB aod IP uoicast. Databasi: usi RDS with mult-AZ diploymiot. Backup: wib aod app sievies backid up wiikly via AMIs, databasi backid up via DB soapshots. Aoswern C Explaoatoo: Amazoo RDS Mult-AZ diploymiots peovidi iohaocid availability aod dueability foe Databasi (DB) Iostaocis, makiog thim a oatueal ft foe peoductoo databasi woekloads. Whio you peovisioo a Mult-AZ DB Iostaoci, Amazoo RDS automatcally ceiatis a peimaey DB Iostaoci aod syocheooously eiplicatis thi data to a staodby iostaoci io a difieiot Availability Zooi (AZ). Each AZ euos oo its owo physically distoct, iodipiodiot iofeasteuctuei, aod is iogioiieid to bi highly eiliabli. Io casi of ao iofeasteuctuei failuei (foe ixampli, iostaoci haedwaei failuei, stoeagi failuei, oe oitwoek diseuptoo), Amazoo RDS piefoems ao automatc failovie to thi staodby, so that you cao eisumi databasi opieatoos as sooo as thi failovie is compliti. Sioci thi iodpoiot foe youe DB Iostaoci eimaios thi sami afie a failovie, youe applicatoo cao eisumi databasi opieatoo without thi oiid foe maoual admioisteatvi iotieviotoo. Bioifts Eohaocid Dueability Mult-AZ diploymiots foe thi MySQL, Oeacli, aod PostgeiSQL iogiois utlizi syocheooous physical eiplicatoo to kiip data oo thi staodby up-to-dati with thi peimaey. Mult-AZ diploymiots foe thi SQL

  3. Sievie iogioi usi syocheooous logical eiplicatoo to achiivi thi sami eisult, imployiog SQL Sievie- oatvi Mieeoeiog tichoology. Both appeoachis safiguaed youe data io thi iviot of a DB Iostaoci failuei oe loss of ao Availability Zooi. If a stoeagi volumi oo youe peimaey fails io a Mult-AZ diploymiot, Amazoo RDS automatcally ioitatis a failovie to thi up-to-dati staodby. Compaei this to a Siogli-AZ diploymiot: io casi of a Siogli-AZ databasi failuei, a usie-ioitatid poiot-io-tmi-eistoei opieatoo will bi eiquieid. This opieatoo cao taki sivieal houes to compliti, aod aoy data updatis that occueeid afie thi latist eistoeabli tmi (typically withio thi last fvi mioutis) will oot bi availabli. Amazoo Aueoea imploys a highly dueabli, SSD-backid vietualizid stoeagi layie pueposi-built foe databasi woekloads. Amazoo Aueoea automatcally eiplicatis youe volumi six ways, aceoss theii Availability Zoois. Amazoo Aueoea stoeagi is fault-tolieaot, teaospaeiotly haodliog thi loss of up to two copiis of data without afictog databasi weiti availability aod up to theii copiis without afictog eiad availability. Amazoo Aueoea stoeagi is also silf-hialiog. Data blocks aod disks aei cootouously scaooid foe ieeoes aod eiplacid automatcally. Ioceiasid Availability You also bioift feom iohaocid databasi availability whio euooiog Mult-AZ diploymiots. If ao Availability Zooi failuei oe DB Iostaoci failuei occues, youe availability impact is limitid to thi tmi automatc failovie takis to compliti: typically uodie ooi miouti foe Amazoo Aueoea aod ooi to two mioutis foe othie databasi iogiois (sii thi RDS FAQ foe ditails). Thi availability bioifts of Mult-AZ diploymiots also ixtiod to plaooid maiotioaoci aod backups. Io thi casi of systim upgeadis liki OS patchiog oe DB Iostaoci scaliog, thisi opieatoos aei appliid fest oo thi staodby, peioe to thi automatc failovie. As a eisult, youe availability impact is, agaio, ooly thi tmi eiquieid foe automatc failovie to compliti. Uoliki Siogli-AZ diploymiots, I/O actvity is oot suspiodid oo youe peimaey dueiog backup foe Mult-AZ diploymiots foe thi MySQL, Oeacli, aod PostgeiSQL iogiois, bicausi thi backup is takio feom thi staodby. Howivie, ooti that you may stll ixpieiioci ilivatid latiociis foe a fiw mioutis dueiog backups foe Mult-AZ diploymiots.  Oo iostaoci failuei io Amazoo Aueoea diploymiots, Amazoo RDS usis RDS Mult-AZ tichoology to automati failovie to ooi of up to 15 Amazoo Aueoea Riplicas you havi ceiatid io aoy of theii Availability Zoois. If oo Amazoo Aueoea Riplicas havi biio peovisiooid, io thi casi of a failuei, Amazoo RDS will atimpt to ceiati a oiw Amazoo Aueoea DB iostaoci foe you automatcally. No Admioisteatvi Iotieviotoo DB Iostaoci failovie is fully automatc aod eiquieis oo admioisteatvi iotieviotoo. Amazoo RDS mooitoes thi hialth of youe peimaey aod staodbys, aod ioitatis a failovie automatcally io eispoosi to a vaeiity of failuei cooditoos. Failovie cooditoos Amazoo RDS diticts aod automatcally eicovies feom thi most commoo failuei scioaeios foe Mult-AZ diploymiots so that you cao eisumi databasi opieatoos as quickly as possibli without admioisteatvi iotieviotoo. Amazoo RDS automatcally piefoems a failovie io thi iviot of aoy of thi followiog: Loss of availability io peimaey Availability Zooi Loss of oitwoek coooictvity to peimaey Computi uoit failuei oo peimaey Stoeagi failuei oo peimaey Noti: Whio opieatoos such as DB Iostaoci scaliog oe systim upgeadis liki OS patchiog aei ioitatid foe Mult-AZ diploymiots, foe iohaocid availability, thiy aei appliid fest oo thi staodby peioe to ao automatc failovie. As a eisult, youe availability impact is limitid ooly to thi tmi eiquieid foe automatc failovie to compliti. Noti that Amazoo RDS Mult-AZ diploymiots do oot failovie automatcally io eispoosi to databasi opieatoos such as loog euooiog quieiis, diadlocks oe databasi coeeuptoo ieeoes.
