Cloudflare teatas, et nad on oma sisuhalduse v\u00f5rgustiku \u00fcle viinud Pingora-proksile, mis on kirjutatud Rust keeles. Uus proksi asendas NGINX-serveri Lua-skriptidega konfiguratsiooni ja t\u00f6\u00f6tleb \u00fcle triljoni p\u00e4ringu p\u00e4evas. T\u00f5detakse, et spetsialiseeritud proksile \u00fcleminek on v\u00f5imaldanud mitte ainult uusi v\u00f5imalusi rakendada ja suurendada turvalisust t\u00e4nu m\u00e4luga turvalisele t\u00f6\u00f6tlemisele, vaid ka j\u00e4rsult t\u00f5sta j\u00f5udlust ja s\u00e4\u00e4sta ressursse \u2014 Pingora lahendus ei n\u00f5ua Lua kasutamist, mis t\u00e4hendab CPU kasutuse v\u00e4hendamist 70% ja m\u00e4lukasutuse v\u00e4henemist 67% sama liiklust\u00f6\u00f6tluse mahu korral. <\/p>\n

Pikka aega rahuldas liikluse proksitamise s\u00fcsteem, mis t\u00f6\u00f6tas kasutajate ja l\u00f5ppsihtkohtade vahel, serveritega<\/a> NGINX ja Lua skriptide p\u00f5hjal Cloudflare'i vajadusi, kuid v\u00f5rgustiku kasvamise ja selle keerukuse suurenemisega osutus universaalne lahendus ebapiisav nii j\u00f5udluse kui ka laiendatavuse ja uute klientide v\u00f5imaluste t\u00e4itmise seisukohalt. Eristi t\u00f5usid probleemid funktsionaalsuse lisamisel, mis \u00fcletas lihtsa v\u00e4rava ja koormuse tasakaalu lahenduse. N\u00e4iteks tekkis vajadus taask\u00e4ivitada p\u00e4ring teisele serverile, serverilt<\/a> varustades seda erineva HTTP-pealkirjade kogumiga. <\/p>\n

Pingoras on rakendatud mitme l\u00f5ime mudel, mis eristab seda protsesside (t\u00f6\u00f6tlejad) baasil olevast arhitektuurist, ning on n\u00e4idanud Cloudflare'i kasutusstsenaariumites (k\u00f5rge liikluse kontsentratsioon erinevatelt saitidelt suure statistilise nihkega) t\u00f5husamat ressursside jaotust CPU tuumade vahel. Eriti paljude tasakaalustamata p\u00e4ringute seondamine NGINX protsessidesse viis tasakaalustamata koormuseni CPU tuumadel, mist\u00f5ttu ressursimahukad p\u00e4ringud ja blokeeriv sisend-v\u00e4ljund aeglustasid teiste p\u00e4ringute t\u00f6\u00f6tlemist. Lisaks ei v\u00f5imaldanud \u00fchenduste r\u00fchmade seondamine t\u00f6\u00f6tlusprotsessidega olemasolevaid \u00fchendusi uuesti kasutada, mis v\u00e4hendas t\u00f6\u00f6 efektiivsust, kui t\u00f6\u00f6tlejaid oli palju. <\/p>\n

NGINX:

\"Cloudflare<\/center> <\/p>\n

Pingora:

\"Cloudflare<\/center> <\/p>\n

Pingora rakendamine on v\u00f5imaldanud v\u00e4hendada uute \u00fchenduste loomise operatsioonide arvu 160 korda ja suurendada taaskasutatavate p\u00e4ringute osakaalu 87,1% -lt 99,92% -ni. Lisaks korduvate \u00fchenduste v\u00e4henemisele ja CPU tuumade t\u00f5husama kasutamisele aitas uue proksi j\u00f5udluse t\u00f5usule m\u00e4rgatavalt kaasa ka nginx'iga kasutatavate aeglaste Lua keele t\u00f6\u00f6tlejate mahaj\u00e4tmine. <\/p>\n

Rust keel on valitud t\u00e4nu sellele, et see v\u00f5imaldab saavutada k\u00f5rget j\u00f5udlust koos m\u00e4lu turvalise k\u00e4itlemise vahenditega. Mainitakse, et vaatamata Cloudflare'i inseneride k\u00f5rgele kvalifikatsioonile ja C keeles kirjutatud koodi \u00fclevaatusele ei ole suudetud v\u00e4ltida vigu, mis p\u00f5hjustavad m\u00e4lu probleeme (n\u00e4iteks HTML parsi vulneraablus). Uue koodi osas r\u00e4\u00e4gitakse Pingora t\u00f5rgete anal\u00fc\u00fcsist, mis osutus mitte rakenduse probleemiks, vaid Linuxi tuuma ja riistvarade t\u00f5rgete vigadeks. <\/p>\n

Lisaks on m\u00e4rkimisv\u00e4\u00e4rne Linus Torvalds'i kommentaar, mis k\u00f5las praegu toimuval Open-Source Summit Europe konverentsil, seoses Rust keele toe lisamisega Linuxi tuumasse. 6.0 tuuma pat\u0161id, mis k\u00e4sitlevad seadme draiverite arendamist Rust'is, ei ole veel lisatud, kuid Linuse s\u00f5nul v\u00f5etakse need t\u00f5en\u00e4oliselt vastu 6.1 tuumas, ta ei plaani integratsiooniga viivitada. Rust'i toe lisamise motivatsiooni, peale positiivse m\u00f5ju turvalisusele, nimetab Linus ka v\u00f5imaluseks t\u00f5sta uute osalejate huvi tuuma arendamise vastu, mis on aktuaalne vanadele meistritele aeglaselt vananedes.
