Ngomso nguLwesihlanu omnyama - kwiiprojekthi ze-Intanethi oku kuthetha ukuba kuya kubakho imithwalo ephezulu kwisayithi. Nkqu nezigebenga azinakukwazi ukumelana nazo, umzekelo, kunye neAmazon ngoSuku lweNkulumbuso ngo-2017.
Sigqibe ekubeni sinike imizekelo embalwa elula yokusebenza ngomncedisi wenyani ukuze siphephe iimpazamo kwaye singabulisi abantu ngephepha le-503 okanye, okubi nakakhulu, malunga ne:blank kunye ne-ERR_CONNECTION_TIMED_OUT. Kushiyeke usuku olunye ukulungiselela.
Ukwandisa izixhobo
Iwebhusayithi idla ngokuba neemodyuli ezahlukeneyo - i-database, iseva yewebhu, inkqubo ye-caching. Nganye kwezi modyuli ifuna iindidi ezahlukeneyo kunye nezixa zezibonelelo. Kuyimfuneko ukuhlalutya kwangaphambili inani lezibonelelo ezisetyenzisiweyo kusetyenziswa iimvavanyo zoxinzelelo kwaye uvavanye isantya sedisk I/O, ixesha leprosesa, inkumbulo, kunye ne-Intanethi ye-intanethi yendawo yakho.
Uvavanyo loxinzelelo luya kukunceda ukuba uchonge imiqobo kwindlela yakho kwaye uzinyuse kwangaphambili. Ngoko, umzekelo, unokuphucula amandla omncedisi wakho ngokunyusa indawo ye-hard drive ngexesha lokunyusa, ukwandisa i-bandwidth yewebhusayithi okanye ukwandisa i-RAM ye-server ebonakalayo. Emva kokunyuswa, ungabuyisela yonke into njengoko ibinjalo, oku kwenziwa kwiakhawunti yakho ngaphandle kokuqhagamshelana nenkxaso yezobuchwepheshe kwaye kuthatha imizuzu embalwa, kodwa kungcono ukwenza oku kwangaphambili nangeeyure zomsebenzi omncinci wabathengi kwindawo.
Zikhusele kuhlaselo lweDDoS kwangaphambili
Iiwebhusayithi ziphazamiseka ngexesha leentsuku zokuthengisa kungekhona nje ngenxa yokunyuka kokunyuka kwabathengi, kodwa nangenxa yokuhlaselwa kweDDoS. Banokuququzelelwa ngabahlaseli abafuna ukuqondisa kwakhona itrafikhi yakho kwizixhobo zabo zokukhohlisa.
Ukuhlaselwa kwe-DDoS kuya kuba nzima ngakumbi yonke imihla. Abahlaseli basebenzisa iindlela ezahlukeneyo, besebenzisa zombini uhlaselo lwe-DDoS kunye nokuhlaselwa kobuthathaka besicelo. Kwiimeko ezininzi, uhlaselo luhamba kunye neenzame zokuqhekeza indawo.
Apha kubalulekile ukulungiselela kwangaphambili kwaye uqhagamshele idilesi ye-IP ekhuselweyo ekuhlaselweni kumncedisi wakho. Kwi-UltraVDS sikhusela iiseva hayi emva kohlaselo, kodwa ubusuku nemini kwaye sihlala simelana nokuhlaselwa ukuya kuthi ga kwi-1.5 Tbps! Ukukhusela amaseva ekuhlaselweni kwe-DDoS, kusetyenziswe uluhlu lwezihlungi, ezixhunywe kwitshaneli ye-Intanethi kunye ne-bandwidth enkulu ngokwaneleyo. Izihluzi zihlala zihlalutya i-traffic edlulayo, zichonga izinto ezingaqhelekanga kunye nomsebenzi ongaqhelekanga wothungelwano. Iipateni zetrafikhi ezingekho mgangathweni ezihlalutywayo ziquka zonke iindlela zokuhlasela ezaziwayo ngoku, kubandakanywa nezo ziphunyezwa ngokusebenzisa i-botnets esasazwayo.
Ukuqhagamshela idilesi ekhuselweyo kumncedisi wenyani, kufuneka ungenise isicelo kwinkonzo yenkxaso yomnikezeli kwangaphambili.
Ukukhawulezisa ukulayisha indawo
Ngexesha lokukhushulwa, umthwalo kwiiseva uyanda, kwaye iifoto kunye namakhadi emveliso kuthatha ixesha elide ukulayisha kwiiwebhusayithi. Kwakhona, ukulayisha amaphepha enziwa nzima ngakumbi ngezakhelo ezahlukeneyo, iilayibrari zeJS, iimodyuli zeCSS, njalo njalo. Umxhasi onokubakho unokulishiya iphepha ngaphandle kokufumana impendulo kwisiza, nokuba isithembiso sithandeka ngakumbi kuneso sikhuphisana nabo. Ukujonga isantya sokulayisha iphepha, sicebisa ukuba usebenzise iGoogle DevTools.
INethiwekhi yokuThuthukiswa koMxholo (CDN) inokunceda ukukhawuleza ukulayishwa kwekhasi. I-CDN yinethiwekhi esasazwe ngokwejografi equka iindawo zokugcina iindawo - iindawo zobukho, zinokufumaneka kwihlabathi liphela. Xa undwendwela indawo, umxhasi uya kufumana umxholo omileyo hayi kwiseva yakho, kodwa kulowo uyinxalenye yenethiwekhi yeCDN kwaye ibekwe kufutshane nayo. Ngokunciphisa indlela phakathi komncedisi kunye nomxhasi, idatha kwisayithi ilayisha ngokukhawuleza.
Ungakwazi ukuseta inethiwekhi ye-CDN ngokwakho ukuba une-VDS kwi-Windows Server Core 2019; ukwenza oku, sebenzisa izixhobo ezakhelwe kwinkqubo yokusebenza efana ne: Active Directory, DFS, IIS, WinAcme, RSAT. Unokusebenzisa izisombululo esele zenziwe, umzekelo, i-CDN evela kwi-Cloudflare inokusombulula ingxaki ngokukhawuleza nangexabiso eliphantsi. Ngaphezu koko, le nkqubo ineempawu ezongezelelweyo: i-DNS, i-HTML compression, i-CSS, i-JS, amanqaku amaninzi obukho.
Ithamsanqa ngeentengiso zakho.
NgoLwesihlanu omnyama kwi-UltraVDS
Kananjalo asizange sizihoye izaphulelo zemveli ngolu suku kwaye sinikeze abasebenzisi beHabr ikhowudi yokuthengisa BlackFr nge-15% isaphulelo kuzo zonke iiseva zethu ezibonakalayo ukusuka nge-28 kaNovemba ukuya kwi-2 kaDisemba.
Ngokomzekelo, iseva kwi-UltraLight tariff ene-1 CPU engundoqo, i-500MB ye-RAM kunye ne-10GB yendawo yedisk eqhuba i-Windows Server Core 2019 inokuthengwa kusetyenziswa ikhowudi yokuthengisa. BlackFr nge-30% isaphulelo esongezelelweyo ngonyaka kwi-ruble ye-55 kuphela ngenyanga, ngoko ke isaphulelo sisonke siya kuba ngama-45% exabiso langoku.
ngumboneleli wamafu wanamhlanje; amakhulu emibutho emikhulu asebenza nathi, kubandakanya iibhanki ezaziwayo-kakuhle, ii-stockbrokers, ulwakhiwo kunye neenkampani zamayeza.
