Kungenzeka yini ukufaka esikhundleni se-Linux njengenhliziyo yezinsizakalo zekhompiyutha zamafu ezingenasiphakeli? Yileyo kanye inhloso yokuqala okuhlanganisa onjiniyela abavela kuphrojekthi yesizindalwazi se-Postgres yomthombo ovulekile kanye nefemu yokuphatha idatha i-Databricks nososayensi bamakhompyutha abavela e-Massachusetts Institute of Technology, Stanford University, nase-UC Berkeley.

Inkampani, i-DBOS, ememezele izigidi ezingama- $ 8.5 ngoxhaso lwembewu ngoMashi 12, ihlose ukwenza lula isitaki samanje esiyinkimbinkimbi esidingekayo ekuthuthukisweni kwamafu ngokufaka esikhundleni seziqukathi ze-Linux ngohlelo lwayo lokusebenza lwe-data-centric (OS). I-OS ilandelela isimo sayo kumathebula esizindalwazi, ngokwendabuko isekela ukufana, futhi yenza ukuphepha kube lula ngokusebenzisa izilawuli zokufinyelela kusizindalwazi somdabu. Ukugxila kwedatha kuzophinde kuvumele ukuthobelana okungcono kanye neziqinisekiso zokusetshenziswa, ngokugawulwa kwemithi okuphelele okuvumela ukusekelwa kobuqotho bedatha, ngokusho kwenkampani.

Ukwakhiwa okulula kanye nekhono lokugawula lendabuko le-OS livumela indawo encishisiwe yokuhlasela kanye nekhono elikhulu lokubona okungaqondakali okungase kubonise ukuhlasela, uma kuqhathaniswa nezakhiwo ze-Linux eziguga, kusho uMichael Coden, umongameli kanye nomsunguli we-DBOS.

"Inani lezinto eziguquguqukayo zombuso ozidingayo kuhlelo lokusebenza lwesimanje liphindwe izikhathi eziyisigidi ngaphezu kwamashumi amathathu eminyaka edlule" ngenkathi kwakhiwa i-Linux, uthi. Ukwenza i-Linux isebenzele izinhlelo zokusebenza zamafu, “sengeze iziqukathi phezu kwe-Linux, futhi sengeze i-Kubernetes phezu kweziqukathi ukuze sizihlele, futhi sengeze i-orchestration yokuhamba komsebenzi ngoba i-Kubernetes inzima kakhulu ukuyisebenzisa. Kuyinto eyinkimbinkimbi, okuyinto ... engavikelekile ngempela ngoba ziningi izingxenye ezihambayo."

I-DBOS ihlose ukushintsha lokho nge isistimu yayo yokusebenza engaziwa, eyadalwa yiqembu labacwaningi abavela e-MIT nase-Stanford - omunye wabasunguli manje use-UC Berkeley - futhi uhloselwe ukwenza lula izakhiwo ze-data-centric serverless. Ephepheni lika-2020, “I-DBOS: Isiphakamiso Sohlelo Lokusebenza Lwedatha Emaphakathi,” abacwaningi bathi balindele ukuthi izinhlelo zokusebenza ezingenasiphakeli nezokufunda ngomshini zizuze ohlelweni olunjalo lokusebenza olwakhelwe inhloso.

I-OS iwukubheja ngekusasa elingenaseva, lapho amakhasimende ebhizinisi ekhokha kuphela izinga asebenzisa ngalo amasevisi. Izinkampani eziningi okungenani zizama le ndlela. Ngaphezu kwe-70% yezinhlangano ezisebenzisa i-Amazon Web Services nazo zisebenzisa amandla epulatifomu angasebenzi, kuyilapho angaphezu kuka-60% wamakhasimende e-Google Cloud kanye nama-49% amakhasimende e-Microsoft Azure asebenzisa lezo zinhlelo zokusebenza ezingenasiphakeli, ngokusho kombiko weDatadog, "I-State of Serverless,” eyanyatheliswa ngo-August.

Ukuphila Kangcono Ngemininingwane Egciniwe?

I-DBOS ihlose ukwenza i-serverless ibe lula ukuyiphakela futhi ivikeleke kakhulu. I-OS ibeka okungenani uhlelo olulodwa lokuphathwa kwesizindalwazi (DBMS) olusebenza ku-microkernel esisekelweni sayo. Isistimu yefayela, izinsiza ze-OS, kanye nenqubo yokuhlela konke kusebenza phezulu kwesendlalelo sesizindalwazi, nezinsiza eziningi ezibhalwe njengezinqubo zesizindalwazi esigciniwe.

Sekukonke, i-architecture ihlinzeka ngezinzuzo ezibalulekile zokusebenza kwezinhlelo zokusebenza ezidinga idatha, kusho u-Qian Li, umakhi wezakhiwo kanye nomsunguli we-DBOS.

"Senze ukulinganisa okubanzi kakhulu phakathi kwesitaki samanje - isitaki esingenaseva - nendlela ye-DBOS, futhi sithole ukuthi sishesha izikhathi eziyi-100 futhi siyingozi kakhulu," kusho yena. "Sithola ngokuhlanganyela isicelo sakho kusizindalwazi, okunciphisa ukuhamba nokubuya okungadingekile [lapho isicelo kufanele sibize idatha eyengeziwe] futhi sisenze sibe sengozini kakhulu ... singakala kalula uhlelo lokusebenza kumaseva amaningi, amaningi."

I-cybersecurity yenkundla engenaseva kuvame ukuba nzima ukuyihlola ngoba amakhasimende avame ukuntula ukubonakala esitakini esingaphansi. Uma ubuchwepheshe, obufana ne-DBOS, bungashintsha lokho, bungase buhehe izinhlelo zokusebenza eziqhutshwa ukuthobela, kusho u-Aradhna Chetal, umqondisi omkhulu wezokuphepha zamafu enhlanganweni yezinsizakalo zezezimali i-TIAA.

"Kumodeli yesibopho esabiwe, ngokuvikeleka kwesicelo ... njengomthwalo wemfanelo womqashi, kuyinselele kancane ukukhombisa ukuphepha kokugcina kwesicelo esisetshenzisiwe - ikakhulukazi endaweni elawulwayo," kusho u-Chetal. “Ukucwaningwa kwamabhuku kungaba yinselele ukukhombisa ngaphandle kokulawula kokuphela. Ubulula buhlala buwumngane wokuphepha, futhi ukusebenziseka kalula kuhlale kunikeza ulwazi olungcono lomsebenzisi, ngokuvamile.”

Ukubheja Ngekusasa Elivikelekile le-Serverless

Lezo zinzuzo zingase zingabonakali kubasebenzisi bokugcina. Imisebenzi engenaseva ifihla ingqalasizinda engemuva - njengeziqukathi, imishini ebonakalayo, ama-OS, nezitaki zohlelo lokusebenza - konjiniyela abasebenzisa amasevisi njengengxenye yezinhlelo zabo zokusebenza.

Ukuthengisa amakhasimende ngezinzuzo zokusebenzisa i-DBOS, izici ezingenaseva ezisekelwe ku-OS zidinga ukuhlinzeka ngenzuzo ebonakalayo kumsebenzisi wokugcina, kusho uDavid Linthicum, umhlaziyi wamafu ozimele kanye nomxhumanisi, olinganisela ukuthi kuphela i-5% kuya ku-10% ye-codebase. ngoba izinhlelo zokusebenza zamafu ezimaphakathi zithathelwe indawo imisebenzi engenasiphakeli.

Nakuba imisebenzi engenasiphakeli ingase yengeze ukusebenza, inkumbulo, nezinzuzo zokuphepha, lokho kuthuthukiswa kuvame ukuvuza umhlinzeki, hhayi umsebenzisi wokugcina, ongase angaboni noma yiziphi izinguquko, uthi.

"Iningi lalezi zici zibhakwa ekhekheni," kuphawula uLinthicum.

Ngaphezu kwalokho, ngenkathi i-DBOS yokuqala ishicilele ikhithi yokuthuthukisa isofthiwe, isistimu yokusebenza ye-DBOS ingumthombo ovaliwe, ongakhawulela ukutholwa futhi wenze ukuthola abalandeli kube inselele enkulu, ikakhulukazi uma i-Linux yomthombo ovulekile isebenza kahle ngokwanele.

Nokho ezokuphepha zingaba umehluko, kusho i-DBOS 'Coden. Kwezinye izimo kusetshenziswa idatha yokuhlasela yangaphambilini, imibuzo ye-DBOS ingathola ukuhlasela ngemizuzwana, uma kuqhathaniswa namahora okuhlasela kwasekuqaleni, uthi.

“Zimbalwa kakhulu izingxenye ezihambayo, futhi zimbalwa izindawo zokuhlasela, njengoba indawo yokuhlasela incane kakhulu,” usho kanje. “Igama lomdlalo lithi, 'Ngingaligcina kanjani ibhizinisi lami lisebenza futhi ngivimbele umonakalo?' Futhi uma kungenxa yekhono lokuphendula ngokushesha, ukululama, nokubuyisela, lokho kuhle ngendlela efanayo nokuvimbela.”
