Kusasa uLwesihlanu Olumnyama - kumaphrojekthi e-inthanethi lokhu kusho ukuthi kuzoba nenani eliphakeme kakhulu esizeni. Ngisho nemidondoshiya ingase ingakwazi ukumelana nazo, isibonelo, ne-Amazon ngoSuku Olukhulu ngo-2017.
Sinqume ukunikeza izibonelo ezimbalwa ezilula zokusebenza ngeseva ebonakalayo ukuze sigweme amaphutha futhi singabingeleli abantu ngekhasi le-503 noma, okubi nakakhulu, okuthi Mayelana:blank kanye ne-ERR_CONNECTION_TIMED_OUT. Sekusele usuku olulodwa ukulungiselela.
Izinsiza zokukala
Iwebhusayithi ivamise ukuba namamojula ahlukene - isizindalwazi, iseva yewebhu, isistimu yokugcina isikhashana. Ngayinye yalawa mamojula idinga izinhlobo ezahlukene kanye namanani ezinsiza. Kuyadingeka ukuhlaziya kusenesikhathi inani lezinsiza ezisetshenziswa kusetshenziswa izivivinyo zokucindezeleka futhi uhlole isivinini sediski I/O, isikhathi sokucubungula, inkumbulo, nomkhawulokudonsa we-inthanethi wesayithi lakho.
Ukuhlolwa kwengcindezi kuzokusiza ukuthi ubone izingqinamba ohlelweni lwakho futhi uzikhulise kusenesikhathi. Ngakho-ke, isibonelo, ungathuthukisa amandla eseva yakho ngokwandisa isikhala se-hard drive ngesikhathi sokukhushulwa, wandise umkhawulokudonsa wewebhusayithi noma ukhuphule i-RAM yeseva ebonakalayo. Ngemuva kokukhushulwa, ungabuyisela yonke into njengoba kwakunjalo, lokhu kwenziwa ku-akhawunti yakho yomuntu siqu ngaphandle kokuxhumana nokusekelwa kwezobuchwepheshe futhi kuthatha imizuzu embalwa, kodwa kungcono ukwenza lokhu kusenesikhathi nangesikhathi samahora omsebenzi omncane wamakhasimende esizeni.
Zivikele ekuhlaselweni kwe-DDoS kusenesikhathi
Amawebhusayithi aphahlazeka phakathi nezinsuku zokuthengisa hhayi nje ngenxa yokwanda kokungena kwamakhasimende, kodwa nangenxa yokuhlaselwa kwe-DDoS. Angahlelwa abahlaseli abafuna ukuqondisa kabusha ithrafikhi yakho kuzisetshenziswa zabo zobugebengu bokweba imininingwane ebucayi.
Ukuhlaselwa kwe-DDoS kuya kuba yinkimbinkimbi nsuku zonke. Izigebengu ze-inthanethi zisebenzisa izindlela ezihlukene, zisebenzisa kokubili ukuhlasela kwe-DDoS nokuhlasela ekubeni sengozini kwezinhlelo zokusebenza. Ezimweni eziningi, ukuhlaselwa kuhambisana nemizamo yokugebenga isayithi.
Lapha kubalulekile ukulungiselela kusengaphambili futhi uxhume ikheli le-IP elivikelwe ekuhlaselweni kuya kuseva yakho. Kwa-UltraVDS asivikeli amaseva ngemva kokuhlaselwa, kodwa ubusuku nemini futhi sihlala simelana nokuhlaselwa okufika ku-1.5 Tbps! Ukuze kuvikelwe amaseva ekuhlaselweni kwe-DDoS, kusetshenziswa uchungechunge lwezihlungi, ezixhunywe esiteshini se-inthanethi esinomkhawulokudonsa omkhulu ngokwanele. Izihlungi zihlaziya ithrafikhi edlulayo, zikhomba okudidayo nomsebenzi wenethiwekhi ongajwayelekile. Amaphethini ethrafikhi angajwayelekile ahlaziywayo ahlanganisa zonke izindlela zokuhlasela ezaziwayo manje, kuhlanganisa nalezo ezisetshenziswe kusetshenziswa ama-botnets asabalalisiwe.
Ukuze uxhume ikheli elivikelwe kuseva ebonakalayo, kufanele uthumele isicelo kusevisi yokusekela yomhlinzeki kusengaphambili.
Sheshisa ukulayisha isayithi
Ngezikhathi zokukhushulwa, umthwalo kumaseva uyakhula, futhi izithombe namakhadi omkhiqizo kuthatha isikhathi eside ukulayisha kumawebhusayithi. Futhi, ukulayisha amakhasi kwenziwa kube nzima kakhulu izinhlaka ezihlukahlukene, imitapo yolwazi ye-JS, amamojula e-CSS, njalonjalo. Umuntu ongase abe iklayenti angase ashiye ikhasi ngaphandle kokuthola impendulo evela kusayithi, noma ngabe ukunikezwa kufaneleka kakhulu kunezimbangi. Ukuhlola isivinini sokulayisha ikhasi, siphakamisa ukusebenzisa i-Google DevTools.
Inethiwekhi Yokulethwa Kokuqukethwe (CDN) ingasiza ukusheshisa ukulayishwa kwekhasi. I-CDN inethiwekhi esabalaliswe ngokwendawo equkethe ama-caching node - amaphuzu okuba khona, angatholakala emhlabeni wonke. Lapho uvakashela isayithi, iklayenti lizothola okuqukethwe okumile hhayi okuvela kuseva yakho, kodwa kulena eyingxenye yenethiwekhi ye-CDN futhi etholakala eduze kwayo. Ngokunciphisa umzila phakathi kweseva neklayenti, idatha kusayithi ilayisha ngokushesha.
Ungakwazi ukusetha inethiwekhi ye-CDN ngokwakho uma une-VDS ku-Windows Server Core 2019; ukwenza lokhu, sebenzisa amathuluzi akhelwe ohlelweni lokusebenza njengalawa: Active Directory, DFS, IIS, WinAcme, RSAT. Ungasebenzisa futhi izixazululo ezenziwe ngomumo, isibonelo, i-CDN evela ku-Cloudflare ingaxazulula inkinga ngokushesha futhi eshibhile. Futhi, lolu hlelo lunezici ezengeziwe: i-DNS, ukucindezelwa kwe-HTML, i-CSS, i-JS, amaphuzu amaningi okuba khona.
Sikufisela inhlanhla ngokuthengisa kwakho.
NgoLwesihlanu Omnyama ku-UltraVDS
Futhi asizange sizibe izaphulelo ezivamile ngalolu suku futhi sinikeze abasebenzisi bakwa-Habr ikhodi yokuphromotha BlackFr ngesaphulelo esingu-15% kuwo wonke amaseva ethu abonakalayo kusukela ngoNovemba 28 kuya kuDisemba 2 kuhlangene.
Isibonelo, iseva ku-UltraLight tariff enomgogodla ongu-1 we-CPU, u-500MB we-RAM kanye no-10GB wesikhala sediski esebenzisa i-Windows Server Core 2019 angathengwa kusetshenziswa ikhodi yokuphromotha. BlackFr ngesaphulelo esengeziwe esingu-30% ngonyaka ngama-ruble angama-55 kuphela ngenyanga, ngakho isaphulelo esiphelele sizoba ngu-45% yenani lamanje.
ungumhlinzeki wamafu wesimanje; amakhulu ezinhlangano ezinkulu asebenza nathi, okuhlanganisa amabhange aziwayo, abadayisi bamasheya, izinkampani zokwakha kanye nemithi.
