Ngohlabathi ye-digital-first namhlanje, ukubuyekeza ukufinyelela kwedatha ngokushesha akuyona isizukulwane – kuyinto kuyimfuneko. Noma ufuna ukulawula isicelo esiyingqayizivele, ukunikezela impahla ye-multimedia kumazwe ngamazwe ngamazwe ngamazwe, noma kuphela ukubuyekeza amafayela zokuxhumana, ukucaciswa kwe-cloud storage yakho kubaluleke ngokuqondile yonke into kusuka ku-productivity kuya ku-confidence. Kodwa ukuthi "ukubuyekezwa" kuncike? Ngokuvamile ama-cloud providers, ukucubungula kubhalwe ngokuvumelana nezinqubo ze-uptime — 99.9%, 99.99%, noma ngisho Nangona kunjalo, emzimbeni yesi-SLAs (i-Service Level Agreements) ivela inkinga eluhlaza: - Umthamo ukufinyelela idatha yakho ngesikhathi noma lapho, ngaphandle kokuphuma noma ukucindezeleka okungenani - ivele. Ngaphandle kwe-centralized clouds enhle kakhulu kubalulekile into esiyingqayizivele eyenza ukucindezeleka: ukuhlangabezana. five nines continuous performance I-Reliability ayikho into esithathwe – kuyinto into esithathwe. Ukusuka ku-region-wide disruptions kuya ku-network routes engabonakaliwe, sinamathela ukuthi isakhiwo se-centralized, nangona kungcono ukuthi i-fortified, ayikwazi ukufinyelela izinzuzo zayo zayo zokusebenza. Uma zonke izitimela zihlanganisa nge-short of data centers, isinyathelo esisodwa esisodwa - i-fire, i-routing issue, i-internal error - ingathuthukisa imiphumela emkhakheni ephelele. Ukusuka ku-region-wide disruptions kuya ku-network routes engabonakaliwe, sinamathela ukuthi isakhiwo se-centralized, nangona kungcono ukuthi i-fortified, ayikwazi ukufinyelela izinzuzo zayo zayo zokusebenza. Uma zonke izitimela zihlanganisa nge-short of data centers, isinyathelo esisodwa esisodwa - i-fire, i-routing issue, i-internal error - ingathuthukisa imiphumela emkhakheni ephelele. Kuleli khulula ukuthi i-architecture ye-Sia eyenziwe ngempumelelo ukuhlangabezana ne-limitations. Ngaphezu kwalokho, i-Sia yenzelwe ukuqinisekisa ukuthi Kuhlolwe kulandelayo, sizobona le design nezimodeli zokuzivakasha, ukuhlangabezana nezimo zokuzivakasha zangaphakathi, futhi zibonisa ukuthi ukuzenzakalelwa akuyona kuphela okungabizi - kuyinto enhle kakhulu. Ukusebenza nge-resilience Ngenxa yokuba kwelanga le-cloud storage, ukucubungula akuyona lokho ungathanda – kuyinto ukuthi ungathuthukisa. I-Fragile Foundations ye-centralized clouds Nge zonke izixazululo zayo ze-"five nine" uptime, i-cloud storage platforms ezivamile ibonise ukuthi isakhiwo se-centralized ingangena ukuthi kungabonakaliswa ngempumelelo se-environmental, ama-human error, noma ama-internal misconfigurations. Ngaphandle kwe-redundancy eyenziwe ngama-hyperscalers afana ne-AWS, i-Google Cloud, ne-Microsoft Azure, izifundo zokusebenza zangempela zibonisa ingozi eyahlukile - okuyinto lapho ama-millions abasebenzisi angakwazi ukufinyelela ngexesha elithile, futhi amabhizinisi ephelele ziye zihambile ngenxa ye-single point ye-failure. Umzekelo we-cloud we-fragility angama-incidents e-datacenter – incidents that can instantly disable entire zones of cloud services. Ngo-Agasti 2022, i-explosion ye-electric at Google's Council Bluffs data center wama-worried three workers and disrupted core services such as Search and Maps. I-event, i-arc flash eyenziwe ngexesha lokusebenza kwe-substation, isebenza njenge-ukudluliselwa ukuthi ngisho amazwe be-industry ayikwazi ukuvikela izinzuzo ezinxulumene ne-physical infrastructure. Ngonyaka elandelayo eParis, isixazululo se-multi-cluster e-Europe-West9-a zone ye-Google Cloud yasungulwa nge-invasion yamanzi - ngokuvamile imiphumela yokungasebenzi kwekhwalithi ye-cooling eyenza ibhethri kanye nokuvimbela isixazululo. Lokhu isixazululo se-cascading akuyona kuphela eyodwa ye-cloud ye-Google eYurophu, kodwa kunesibopho se-cloud angaphezu kuka-90 ngexesha elide. Lezi zincwadi zihlanganisa umkhosi we-2021 OVHcloud e-Strasbourg, okuyinto wahlukanise ngokuphelele i-SBG2 data center futhi ngempumelelo ezinye ezivela e-campus efanayo. Many customers had no disaster recovery plans in place, and entire websites were lost without backups. Ngezingu-2022, izinga lokushisa ezingu-40 ° C (104 ° F) eLondon zithintela ama-Google ne-Oracle data centers ngaphandle kwe-offline ngenxa yokungasebenzi kwezistimu ze-cooling. I-Google yayingathwe ngokuvamile izinhlayiya ze-cloud yokuvimbela ukuchithwa kwe-hardware. Kodwa-ke, akukho zonke izixazululo zihlanganisa isifo se-catastrophe yemvelo – ezinye izixazululo ze-digital ezihlangene. NgoFebruwari 2024, i-Google Cloud isitholela isixazululo esilandelayo lapho isiteshi se-metadata yesifunda senze isixazululo se-US-West1 isixazululo se-off for cishe amahora angu-3. Ngokusho, ukuhlaziywa okuqhubekayo ka-CrowdStrike ngoJulayi 2024 yenza isixazululo esikhulu se-Microsoft Windows systems, okwenza amayunithi amayunithi asuswe kanye nokunciphisa ukukhiqizwa emikhulu emhlabeni wonke. Uma inethiwekhi ye-Content Delivery Network (CDN) efana ne-Fastly wathatha isizukulwane esisodwa ngo-2021, kubangeli izixazululo zehlabathi, okuphendula i-Reddit, i-Spotify, kanye namasevisi eziyinhloko emizuzu eminyakeni. Isizathu? Isizukulwane esisodwa sokukhuthaza emhlabeni wonke ngenxa ye-monoculture yama-CDN. Ukusebenza okuqhubekayo nge-design Uma abaphakeli we-centralized cloud zibonisa izixazululo ezininzi zokuphefumula ukuphazamiseka, i-Sia isixazulula inkinga ngokugcwele ngokuvimbela imodeli ye-fortress. Ngaphandle kokubeka konke ku-resilience ye-region noma isakhiwo eyodwa, i-Sia isixazulula idatha yakho emhlabeni wonke, ku-dozen ye-nodes eyenziwe ngokuzimela, usebenzisa imathemikhali - ngaphandle kwe-marketing - ukuhlinzeka ukuzinza. It is not just a different infrastructure - it is a different philosophy. Ukushintshwa okuvumela I-redundancy isetshenziswe ngokuvamile njenge-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa-ukudluliselwa. Ngokuvamile, i-Sia iveza idatha ngamunye ku-30 i-shards encrypted ngokusebenzisa i-coding yokushicilela. Kungenani amahhotela amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi amayunithi. I-redundancy is a fallback – it is the foundation of continuous performance. Ngaphandle kwalokho, ama-cloud ezivamile zihlanganisa ukuxhumana kwe-file ephelele kumazwe amaningi. Uma i-region eyinkimbinkimbi, ukufinyelela isizinda noma isixazululo - futhi isitoreji esizayo asho isivinini esihle. I-Sia model ivimbele ngokushesha. Izindlela ze-Retrieval zihlanganisa ngokushesha ngokuvumelana ne-host availability ne-network conditions - akukho ama-failovers, akukho ama- bottlenecks, akukho ama-stoptime windows. Nangona i-centralized cloud ingasebenzisa ukwahlukanisa ukucubungula kwebhizinisi, zonke izakhiwo zayo zikhuthaze umphakeli eyodwa. Isisindo esisodwa ingathuba inethiwekhi ephelele. I-hosts ye-Sia, ngokuvamile, isetshenziselwa ngokuzimela - ngokuvamile abasebenzi ezahlukene. Ukusetshenziswa kwe-Sia kuyinto efana nokuhlanganisa idatha yakho ku-cloud ezingu-30 ngokuzimela. Akukho inkampani eyodwa ukulawula uhlelo, futhi akuyona inkinga elilodwa akuyona. Resilience ngaphandle ukucindezeleka Ngama-cloud emkhakheni, lapho yini ibheka, ukusebenza ibheka. Ngaphandle kwezinhlelo zokusebenza, ukucubungula ngokuvamile kuholele ngesivinini ephakeme, ukufinyelela okuphazamiseka, noma isikhathi esizayo ephakeme ngenkathi isakhiwo ibheka ukuguqulwa. I-Architecture ye-Sia isebenza ngokufanayo. Uma i-host enikeza ingxenye yebhizinisi yakho ivuka ngaphandle kwe-offline - noma ngenxa yokungasebenzi, ukugcinwa, noma ukucindezeleka - amafayela akho zihlanganisa ngokuphelele. Akukho ukulayisha i-spinner, akukho i-sync lag, akukho i-alert. Inethiwekhi ivumela ukulayisha ama-shards ezidingekayo ezahlukile, ukhethe ngokushesha izinketho ezinikezwayo. Zonke okuholela emangalisayo. Nge-background, isofthiwe se-renter uqala ukuguqulwa ngokuvumelana ngokuphelele ngokuvumelana nokulanda ama-shards ezintsha kumadokhumenti ezinhle. Le nqubo yokuguqulwa okuzenzakalelayo akuvimbela kuphela imiphumela emkhakheni elandelayo – kuqinisekisa ukuthi ukusebenza akuyona ngokushesha. Sia akuyona kuphela kusukela kwangapheli - it ukusebenza ngokusebenzisa. Ngaphandle kokuphendula isisindo ngemuva kokufika, i-Sia isihlanganisa i-churn njenge-comportment esithathelwe - okuhlobene inethiwekhi ngokufanelekileyo. Kuyinto imodeli yokuthintela ukuthi akuvimbela kuphela izixazululo - okuvimbela abasebenzisi ngokuvamile ngaphandle kokufaka. Akukho point ye-Failure I-centralized cloud platform ihambelana ne-cascading failure ngoba zihlanganisa ku-centralized control. I-router eyenziwe ngempumelelo, isisombululo se-software emibi, noma isisombululo se-power ku-installation eyodwa, ingatholakala kumazwe ngamazwe ngamazwe. I-Architecture ye-Sia ikhoyizi le-risk ngokucophelela. Akukho i-master node. Akukho i-central region. Akukho i-privileged authority eyenza inkqubo ngaphandle kokufanele. Ngaphandle kwalokho, idatha yakho ibhekwa kumazwe amaningi e-host ehlabathini lonke — ngamunye iholide kuphela ama-shards encrypted. Uma i-host eyahlukile, uhlelo ivela. Uma ama-host ezingu-10 ivela, ivela futhi. Akunemfuneko "ukungabikho" ngoba akukho indlela eyodwa yokuqala. No region. No master node. No bottleneck. Just ukufinyelela unstoppable. Ukungabikho kwe-dependence ye-central akuyona kuphela ukwanda kwe-defect tolerance - it Ingabe ufuna ukushumeka kokuthunyelwe kwebhizinisi? Ingabe ufuna ukushumeka kokuthunyelwa kokuthunyelwe kwebhizinisi? Ingabe ufuna ukushumeka kokuthunyelwe kwebhizinisi? Ingabe ufuna ukushumeka kokuthunyelwe kwebhizinisi? prevents performance blackouts Ukucubungula ukucubungula, akuyona kuphela Uma thwebula "ukwethenjelwa kwe-cloud", sinikeza isixazululo - i-SLA esekelwe izimpendulo zebhizinisi, izinga lokuphumelela okuhlobene, kanye ne-brand reputation. Kodwa njengoba thwebula, ngisho ama-cloud providers amakhulu ayikwazi ukuvikela ukuzinza okuqukethwe okuqukethwe kwe-centralization. Noma i-fire, i-heat waves, noma i-software missteps, imodeli ye-cloud ephakeme kunazo zonke izixazululo eziningana nezimo ze-global disruption. Sia usebenzisa indlela eyahlukile. Ngaphandle kokufunda ukuthi izinhlelo zokusebenza futhi zihlanganisa isixazululo lapho akufanele, Sia isithathwa ukuthi isixazululo kuyimfuneko - futhi isakhiwo uhlelo esebenza nangona kunjalo. Kuyinto ingxenye yayo. : akukho i-server eyenziwe, akukho izilinganiso zendawo, akukho i-vendor lock-in. I-self-repair, isakhiwo se-decentralized elihlanganisa idatha yakho yokufinyelela ngoba akukho umlingani omunye inesibopho yokwenza engatholakali. Ukusebenza okuqhubekayo Kuyinto ngaphezulu kwe-avantage yobuchwepheshe. Kuyinto ukuguqulwa kwindlela etholakalayo yokuthintela kwedijithali. Ngaphandle kokwakha izindandatho ezingaphezulu kanye nezindandatho ezingaphezulu, i-Sia ibonise izindandatho zayo. I-Sia ibonise ukunakekelwa. Futhi ngokwenza lokhu, i-Sia ibonise ukuthi isitoreji se-cloud enokutholakalayo ingangena emhlabeni lapho isikhathi se-stay isizukulwane engatholakali. Njengoba izinhlelo zangaphakathi zihlanganisa, izindleko eziningana, kanye nezidingo zokuhambisana ezinzima, i-decentralization iyatholakala kakhulu - kuyinto engcono. Uma elandelayo we-cloud iyatholakala ekukhiqizeni izinsizakalo ezisebenzayo Nokho, ngisho lapho izimo zithembisa, ke kunzima ukucubungula ngokuvumelana ne-confidence futhi ukuqala ukucubungula ngokuvumelana ne-certification. Ukusebenza kuphela Nge-Sia, ukusebenza okuqhubekayo ayikho izinga lokusebenza. Kuyinto inkinga. Izinsiza I-Data Center Knowledge. (2022, Aug. 9).
