Iindlela ezingaqondakaliyo zomxholo okanye makhe sithethe ngeCDN

Ukuzihlangula:
Eli nqaku aliqulathanga ulwazi olungaziwa ngaphambili kubafundi abaqhelene nombono weCDN, kodwa lukuhlobo lophononongo lwetekhnoloji.

Iphepha lewebhu lokuqala lavela ngo-1990 kwaye yayizibhayithi ezimbalwa ngobukhulu. Ukusukela ngoko, umxholo uye walinganisa ngokomgangatho nangokobungakanani. Uphuhliso lwe-IT ecosystem lukhokelele kwinto yokuba amaphepha ewebhu anamhlanje alinganiswa ngeemegabytes kwaye umkhwa wokwandisa umda womnatha womnatha uqiniswa kuphela ngonyaka. Ababoneleli bomxholo banokugubungela njani izikali ezinkulu zejografi kwaye babonelele abasebenzisi kuyo yonke indawo ngesantya esiphezulu sokufikelela kulwazi? Ukuhanjiswa komxholo kunye nokuhanjiswa kwenethiwekhi, okwakwaziwa ngokuba yiNethiwekhi yokuThuthukiswa koMxholo okanye ngokulula i-CDN, kufuneka ijamelane nale misebenzi.

Kukho umxholo "onzima" ngakumbi kwi-Intanethi. Kwangaxeshanye, izifundo ezininzi zibonisa ukuba abasebenzisi abafuni kujongana neenkonzo zewebhu ukuba bathatha ixesha elide kune-4-5 imizuzwana ukulayisha. Isantya esisezantsi kakhulu sokulayisha indawo sigcwele ukulahleka kwabaphulaphuli, okuya kuthi ngokuqinisekileyo kukhokelela ekunciphiseni kwetrafikhi, ukuguqulwa, kwaye ke inzuzo. Amanethiwekhi okuhanjiswa komxholo (CDNs), kwithiyori, aphelise ezi ngxaki kunye neziphumo zazo. Kodwa eneneni, njengesiqhelo, yonke into igqitywe ngeenkcukacha kunye ne-nuances yemeko ethile, apho kukho intabalala kule ndawo.

Uvela phi umbono wokusasazwa kothungelwano?

Masiqale ngohambo olufutshane lwembali kunye neenkcazo zamagama. I-CDN yinethiwekhi yeqela loomatshini beseva ebekwe kwiindawo ezahlukeneyo ukunika ukufikelela kumxholo we-Intanethi ogubungela inani elikhulu labasebenzisi. Umbono wothungelwano olusasazwayo kukuba neendawo ezininzi zobukho (PoP) ngaxeshanye, ezibekwe ngaphandle kweseva yomthombo. Inkqubo enjalo iya kuqhuba uluhlu lwezicelo ezingenayo ngokukhawuleza, ukwandisa impendulo kunye nesantya sokudluliselwa kwayo nayiphi na idatha.

Ingxaki yokuhambisa umxholo kubasebenzisi yavela ngokukhawuleza kwincopho yophuhliso lwe-Intanethi, oko kukuthi. phakathi 90s. Iiseva zelo xesha, ukusebenza kwazo kwakungafikeleli nakwiilaptops zale mihla, zazingakwazi ukumelana nomthwalo kwaye azikwazi ukumelana nokunyuka kwetrafikhi. UMicrosoft uchithe amakhulu ezigidi zeerandi ngonyaka kuphando olunxulumene nohola wendlela yolwazi (edumileyo i-640 KB evela kuBill Gates ifika kwangoko engqondweni). Ukusombulula le miba, kwafuneka sisebenzise i-caching hierarchical, sitshintshe ukusuka kwimodem ukuya kwifiber optics, kwaye sihlalutye i-topology yenethiwekhi ngokweenkcukacha. Le meko yayisikhumbuza ngesikhululo sikaloliwe esidala, esigxalathelana koololiwe kwaye endleleni sihlaziywa ngokwazo zonke iindlela zokwandisa isantya.

Kakade ekupheleni kweminyaka engama-90, abanikazi bee-portal zewebhu baqaphela ukuba ukunciphisa umthwalo kunye nokubonelela ngezicelo ezifunekayo, kufuneka basebenzise amaseva aphakathi. Le yindlela ezavela ngayo ii-CDN zokuqala, zisasaza umxholo omileyo osuka kwiiseva ezahlukeneyo ezisasazeke ngokwejografi emhlabeni jikelele. Ngexesha elifanayo, kwavela ishishini elisekelwe kuthungelwano olusasazwayo. Umboneleli omkhulu weCDN (ubuncinci) kwihlabathi, u-Akamai, waba nguvulindlela kule ndawo, eqala uhambo lwakhe kwi-1998. Kwiminyaka embalwa kamva, i-CDN yanda kakhulu, kwaye ingeniso evela ekuhanjisweni komxholo kunye negalelo lafikelela kumashumi ezigidi zeedola ngenyanga.

Namhlanje sidibana ne-CDN rhoqo xa sisiya kwiphepha lezorhwebo eliphezulu okanye ukunxibelelana kwiintanethi zentlalo. Inkonzo inikezelwa ngu: Amazon, Cloudflare, Akamai, kunye nabanye abaninzi ababoneleli bezizwe ngezizwe. Ngaphezu koko, iinkampani ezinkulu zivame ukusebenzisa ii-CDN zazo, ezizisa inani leenzuzo kwisantya kunye nomgangatho wokuhanjiswa komxholo. Ukuba i-Facebook ayizange isasaze uthungelwano, kodwa yayine-server yemvelaphi kuphela e-United States, kunokuthatha ixesha elide ukulayisha iprofayili yabasebenzisi baseMpuma Yurophu.

Amagama ambalwa malunga ne-CDN kunye nokusasaza

I-FutureSource Consulting yahlalutya ishishini lomculo kwaye yagqiba kwelokuba ngo-2023 inani lababhalisele iinkonzo zokusasaza umculo liya kufikelela phantse kwisiqingatha sebhiliyoni yabantu. Ngaphezu koko, iinkonzo ziya kufumana ngaphezu kwe-90% yengeniso yazo kwi-audio yokusakaza. Imeko enevidiyo iyafana; amagama anje ngokuba masidlale, ikonsathi ye-intanethi kunye ne-cinema ekwi-intanethi sele imiliselwe kwisichazi-magama esidumileyo. I-Apple, uGoogle, iYouTube kunye nezinye iinkampani ezininzi zineenkonzo zazo zokusasaza.

Kwintshayelelo yayo yokuqala, i-CDN yayisetyenziselwa ikakhulu iziza ezinomxholo we-static. I-Static ingcaciso engatshintshi ngokuxhomekeke kwizenzo zomsebenzisi, ixesha kunye nezinye izinto, okt. ayenzelwanga mntu. Kodwa ukunyuka kwevidiyo yokusasaza kunye neenkonzo zeaudio yongeze enye imeko yokusetyenziswa okuqhelekileyo kuthungelwano olusasazwayo. Iiseva eziphakathi, ezikufutshane nabaphulaphuli ekujoliswe kuzo kwihlabathi jikelele, zenza kube lula ukubonelela ukufikelela okuzinzile kumxholo ngexesha lomthwalo ophakamileyo, ukuphelisa ukungabikho kweebhotile ze-Intanethi.

ntoni lo msebenzi

Ingundoqo yazo zonke ii-CDN ziphantse zifana: sebenzisa abalamli ukuze bakwazi ukuhambisa umxholo kumthengi wokugqibela ngokukhawuleza. Isebenza ngolu hlobo lulandelayo: umsebenzisi uthumela isicelo sokukhuphela ifayile, ifunyenwe ngumncedisi we-CDN, owenza umnxeba wexesha elilodwa kumncedisi wokuqala kwaye unike umxholo kumsebenzisi. Ngokuhambelana noku, i-CDN igcina iifayile zexesha elithile kwaye iqhube zonke izicelo ezilandelayo ezivela kwi-cache yayo. Ngokuzikhethela, banokulayisha kwakhona iifayile kwiseva yomthombo, bahlengahlengise ixesha lokugcinwa kwe-cache, bacinezele iifayile ezinzima, kunye nokunye okuninzi. Kwimeko efanelekileyo kakhulu, umphathi udlula umlambo wonke kwi-CDN node, esele isebenzisa izixhobo zayo ukuhambisa umxholo kubasebenzisi. Ihamba ngaphandle kokuthetha ukuba i-caching esebenzayo yolwazi, kunye nokuhanjiswa kwezicelo kungekhona kwiseva enye, kodwa kwinethiwekhi, kuya kukhokelela kumthwalo olinganiselayo wetrafikhi.

Inqaku lesibini elibalulekileyo lomsebenzi we-CDN kukuncitshiswa kokulibaziseka kokuhanjiswa kwedatha (ekwabizwa ngokuba yi-RTT - ixesha lokuya nokubuya). Ukuseka uxhumano lwe-TCP, ukukhuphela umxholo wemidiya, ifayile ye-JS, ukuqala iseshoni ye-TLS, konke oku kuxhomekeke kwi-ping. Ngokucacileyo, ukusondela kwakho kumthombo, ngokukhawuleza unokufumana impendulo kuyo. Emva koko, isantya sokukhanya sinomda walo: malunga ne-200 amawaka eekhilomitha / s nge-fiber optical. Oku kuthetha ukuba ukusuka eMoscow ukuya eWashington ukulibaziseka kuya kuba malunga ne-75 ms kwi-RTT, kwaye oku ngaphandle kwempembelelo yezixhobo eziphakathi.

Ukuqonda ngcono ukuba zeziphi iingxaki zothungelwano losasazo lomxholo ezisombululayo, nalu uluhlu lwezisombululo zangoku:

• I-Google, i-Yandex, i-MaxCDN (sebenzisa ii-CDN zamahhala ukusabalalisa iilayibrari ze-JS, zibe namanqaku angaphezu kwama-90 obukho kumazwe amaninzi ehlabathi);
• Cloudinary, Cloudimage, Google (iinkonzo zokwandisa umxumi kunye namathala eencwadi: imifanekiso, iividiyo, iifonti, njl.);
• Jetpack, Incapsula, Swarmify, njl. (ukusetyenziswa kakuhle kwezibonelelo kwiinkqubo zolawulo lomxholo: i-bitrix, i-wordpress, njl.);
• I-CDNVideo, i-StackPath, i-NGENIX, i-Megafon (i-CDN yokuhambisa umxholo we-static, osetyenziswa njengothungelwano lwenjongo ngokubanzi);
• Imperva, Cloudflare (izisombululo zokukhawulezisa ukulayisha iwebhusayithi).

Iintlobo ze-3 zokuqala ze-CDN kuluhlu zenzelwe ukudlulisa kuphela inxalenye yetrafikhi ukusuka kumncedisi oyintloko. I-2 eseleyo isetyenziswa njengeeseva zommeli ezipheleleyo kunye nokuhanjiswa okupheleleyo kwamatshaneli ukusuka kumamkeli womthombo.

Kubani kwaye ziziphi iingenelo ezibonelela ngobuchwephesha?

Kwithiyori, nayiphi na iwebhusayithi ethengisa iimveliso / iinkonzo zayo kubaxhasi beenkampani okanye abantu ngabanye (i-B2B okanye i-B2C) inokuzuza ekuphumezeni i-CDN. Kubalulekile ukuba abaphulaphuli abajoliswe kubo, okt. isiseko somsebenzisi sasingaphandle kwendawo yabo yejografi. Kodwa nokuba oku akunjalo, uthungelwano losasazo luya kunceda ngokulinganisa umthwalo kwimiqulu emikhulu yomxholo.

Akukho mfihlo ukuba isibini samawaka imisonto yanele ukuvala ijelo lomncedisi. Ke ngoko, ukusasaza ukusasazwa kwevidiyo kuluntu ngokubanzi kuya kukhokelela ekubunjweni kwebhodlela-i-bandwidth yesitishi se-Intanethi. Sibona into efanayo xa kukho imifanekiso encinci, engabonakaliyo kwiwebhusayithi (umboniso wemveliso, umzekelo). Umncedisi wemvelaphi usebenzisa uqhagamshelo lwe-TCP enye xa kusenziwa naliphi na inani lezicelo, eziya kufola ukukhuphela. Ukongeza i-CDN yenza kube yimfuneko ukusasaza izicelo kwiindawo ezininzi kwaye usebenzise uxhulumaniso oluninzi lwe-TCP, ukukhulula umthwalo wesiteshi. Kwaye ifomula yokulibaziseka kokujikeleza, nakwiimeko ezibuhlungu kakhulu, inika ixabiso le-6-7 RRT kwaye ithatha ifom: TCP + TLS + DNS. Oku kukwabandakanya ulibaziseko olunxulunyaniswa nokuvula isitishi sikanomathotholo kwisixhobo kunye nokusasaza umqondiso kwiinqaba zeeseli.

Emva kokushwankathela amandla etekhnoloji kwishishini le-Intanethi, iingcali zigxininisa la manqaku alandelayo:

1. Ukwandiswa kweziseko zophuhliso okukhawulezayo + ukuncitshiswa kwe-bandwidth. Abancedisi abaninzi = amanqaku amaninzi apho ulwazi lugcinwa khona. Ngenxa yoko, inqaku elinye liqhuba i-traffic encinci kwiyunithi nganye yexesha, okuthetha ukuba inokuba ne-throughput encinci. Ukongeza, izixhobo zokuphucula ziyadlala, zikuvumela ukuba umelane nemithwalo ephezulu ngaphandle kokuchitha ixesha.
2. I-ping encinci. Sele sichazile ukuba abantu abathandi ukulinda ixesha elide kwi-Intanethi. Ke ngoko, i-ping ephezulu inegalelo kumazinga aphezulu okubhampa. Ulibaziseko lunokubangelwa ziingxaki zokusetyenzwa kwedatha kwiseva, ukusetyenziswa kwesixhobo esidala, okanye ngokulula kucingelwa kakubi itopology yenethiwekhi. Uninzi lwezi ngxaki zisonjululwa ngokuyinxenye ngothungelwano losasazo lomxholo. Nangona kubalulekile ukuqaphela apha ukuba inzuzo yangempela yokuphumeza iteknoloji iya kubonakala kuphela xa "i-ping yabathengi" idlula i-80-90 ms, kwaye lo ngumgama ukusuka eMoscow ukuya eNew York.

   

3. Ukhuseleko lwedatha. I-DDos (i-Denial of Service virus attack) ijolise ekutshitshiseni umncedisi ukuze ufumane inzuzo ethile. Iseva enye ichaphazeleka kakhulu kubuthathaka bokhuseleko lolwazi kunenethiwekhi esasazwayo (ukufaka isiseko sesikhululo esinjenge CloudFlare ayingomsebenzi olula). Ngombulelo ekusebenziseni izihluzi kunye nokusasazwa ngokufanelekileyo kwezicelo kwinethiwekhi, unokuthintela ngokulula ubunzima obudalwe ngobuchule kunye nokufikelela kwitrafikhi esemthethweni.
4. Ukuhanjiswa komxholo okhawulezayo kunye nemisebenzi yenkonzo eyongezelelweyo. Ukusasaza inani elikhulu lolwazi kwinethiwekhi yeseva kuya kwenza kube lula ukuhambisa unikezelo kumthengi wokugqibela. Kwakhona, awudingi ukujonga kude kwimizekelo- khumbula nje iAmazon kunye neAliExpress.
5. Ukukwazi "ukugubungela" iingxaki kunye nesayithi eliphambili. Akukho mfuneko yokulinda de i-DNS ihlaziywe; ungayidlulisela kwindawo entsha kwaye usasaze umxholo ogcinwe ngaphambili. Oku ke kungaphucula ukunyamezela iimpazamo.

Sizihlele kakuhle izinto eziluncedo. Ngoku makhe sijonge ukuba yeyiphi i-niches ezuzayo kule nto.

Ishishini lentengiso

Intengiso yinjini yenkqubela phambili. Ukuthintela ukuba injini ingatshi, kufuneka ilayishwe ngokuphakathi. Ngoko ishishini leentengiso, elizama ukujamelana nehlabathi ledijithali lanamhlanje, lijongene neengxaki "zomxholo onzima". Imidiya enzima ibhekisa kwintengiso yemultimedia (ingakumbi iibhena ezinopopayi kunye neevidiyo) ezifuna i-bandwidth ephezulu yenethiwekhi. Iwebhusayithi enemultimedia ithatha ixesha elide ukulayisha kwaye inokukhenkceza, ivavanya amandla emithambo-luvo yabasebenzisi. Uninzi lwabantu luyazishiya ezo zixhobo kwanangaphambi kokuba zikhuphele zonke iinkcukacha ezikhoyo. Iinkampani zentengiso zinokuthatha ithuba le-CDN ukusombulula ezi ngxaki.

Ukuthengisa

I-E-commerce idinga ukwandisa rhoqo ukhuseleko lwejografi. Elinye inqaku elibalulekileyo ngumlo ochasene nabantu okhuphisana nabo, apho kukho okuninzi kuwo onke amacandelo emarike. Ukuba iwebhusayithi ayihambelani neemfuno zomsebenzisi (kubandakanywa nokuthatha ixesha elide ukulayisha), ayiyi kuthandwa kwaye ayiyi kukwazi ukuzisa ukuguqulwa okuphezulu okuqhubekayo. Ukuphumeza i-CDN kufuneka ibonise inzuzo yayo ekuphatheni izicelo zedatha ezivela kwiindawo ezahlukeneyo. Kwakhona, ukuhanjiswa kwetrafikhi kuya kunceda ukukhusela i-spikes ye-traffic kunye nokungaphumeleli kweseva elandelayo.

Amaqonga anomxholo wokuzonwabisa

Zonke iintlobo zamaqonga okuzonwabisa zifanelekile apha, ukusuka ekukhupheleni iimuvi kunye nemidlalo ukuya kwiividiyo zokusasaza. Ngaphandle kwento yokuba itekhnoloji isebenza ngedatha engatshintshiyo, idatha yokusasaza inokufikelela kumsebenzisi ngokukhawuleza ngokuphinda. Kwakhona, i-caching ye-CDN yolwazi lusindiso kubanini beephothali ezinkulu - ukugcinwa kwemultimedia.

Imidlalo ye-Intanethi

Imidlalo ye-Intanethi kufuneka ibekwe kwicandelo elahlukileyo. Ukuba intengiso ifuna i-bandwidth enkulu, ke iiprojekthi ze-intanethi zifuna izixhobo ezingakumbi. Ababoneleli bajongene nengxaki enamacala amabini: isantya sokufikelela kwiiseva + ukuqinisekisa ukusebenza okuphezulu kwemidlalo ngemizobo entle. I-CDN yemidlalo ye-intanethi lithuba lokuba nezinto ezibizwa ngokuba “ziindawo zokutyhala” apho abaphuhlisi banokugcina imidlalo kwiiseva ezikufutshane nabasebenzisi. Oku kukuvumela ukuba unciphise impembelelo yesantya sofikelelo kwiseva yokuqala, kwaye ke ngoko uqinisekise umdlalo okhululekileyo kuyo yonke indawo.

Kutheni i-CDN ingekho i-panacea

Ngaphandle kweenzuzo ezicacileyo, ayinguye wonke umntu kwaye akasoloko ezama ukwazisa itekhnoloji kwishishini labo. Kutheni kunjalo? Ngokumangalisayo, ezinye izinto ezingeloncedo zilandela kwizinto eziluncedo, kunye namanye amanqaku anxulumene nokusasazwa kwenethiwekhi ayongezwa. Abathengisi baya kuthetha kakuhle malunga nazo zonke izibonelelo zobuchwepheshe, ukulibala ukukhankanya ukuba zonke ziba zingenantsingiselo kwiimeko ezininzi. Ukuba sijonga izinto ezingeloncedo zeCDN ngokweenkcukacha ngakumbi, kufanelekile ukugqamisa:

• Sebenza kuphela ngee-statics. Ewe, uninzi lweewebhusayithi zanamhlanje zinepesenti ephantsi yomxholo oguqukayo. Kodwa apho amaphepha enziwe umntu, i-CDN ayiyi kukwazi ukunceda (ngaphandle kokuba mhlawumbi ikhuphe inani elikhulu lezithuthi);
• Ukulibaziseka kwe-caching. Ukuphucula ngokwayo yenye yeenzuzo eziphambili zothungelwano lokuhambisa. Kodwa xa usenza utshintsho kumncedisi wemvelaphi, kuthatha ixesha phambi kokuba iCDN iyifumane kwakhona kuzo zonke iiseva zayo;
• Iibhloko ezininzi. Ukuba nangasiphi na isizathu idilesi ye-IP ye-CDN ivaliwe, ke zonke iisayithi ezibanjwe kuyo zivaliwe;
• Kwiimeko ezininzi, isikhangeli siya kwenza imidibaniso emibini (kwimvelaphi yeseva kunye neCDN). Kwaye ezi milliseconds ezongezelelweyo zokulinda;
• Ukubophelela kwidilesi ye-IP yeeprojekthi (kubandakanywa nezingekhoyo) ezazinikezelwe kuyo ngaphambili. Ngenxa yoko, sifumana i-rankings enzima kwi-Google search bots kunye nobunzima ekuziseni isayithi phezulu ngexesha lokunyuswa kwe-SEO;
• I-CDN node yindawo enokubakho yokungaphumeleli. Ukuba uyazisebenzisa, kubalulekile ukuqonda kwangaphambili indlela umzila wenkqubo osebenza ngayo kwaye zeziphi iimpazamo ezinokuthi zenzeke ngelixa usebenza nesayithi;
• Yinto encinci, kodwa kufuneka uhlawulele iinkonzo zokuhanjiswa komxholo. Ngokubanzi, iindleko zilingana nomthamo wezithuthi, nto leyo ethetha ukuba kungafuneka ulawulo lokucwangcisa uhlahlo lwabiwo-mali.

Inyaniso ebalulekileyo: nokuba ukusondela kwe-CDN kumsebenzisi akuqinisekisi i-ping ephantsi. Indlela inokwakhiwa ukusuka kumxhasi ukuya kumamkeli obekwe kwelinye ilizwe okanye kwelinye ilizwekazi. Oku kuxhomekeke kumgaqo-nkqubo womzila womnatha othile kunye nobudlelwane bayo nabaqhubi be-telecom (ukubona). Ababoneleli abaninzi be-CDN abakhulu banezicwangciso ezininzi, apho iindleko zichaphazela ngokuthe ngqo ukusondela kwendawo yobukho xa uhambisa umxholo kubasebenzisi abajoliswe kuyo.

Kukho amathuba - uqalise iCDN yakho

Ngaba awonwabanga ngemigaqo-nkqubo yeenkampani ezibonelela ngeenkonzo zenethiwekhi yokusasazwa komxholo, kodwa ishishini lakho lifuna ukwandisa? Ukuba kuyenzeka, kutheni ungazami ukusungula iCDN yakho. Oku kunengqiqo kwiimeko ezilandelayo:

• Iindleko zangoku zokusasazwa komxholo azihlangabezani nokulindelweyo kwaye azichanekanga ngokwezoqoqosho;
• Sidinga i-cache esisigxina, ngaphandle kokusondela kwezinye iisayithi kumncedisi kunye nesiteshi;
• Abaphulaphuli ekujoliswe kubo bakwingingqi apho kungekho manqaku e-CDN afumanekayo kuwe;
• Isidingo sokwenza useto lolwakho xa uhambisa umxholo;
• Kukho imfuneko yokukhawulezisa ukuhanjiswa komxholo oguquguqukayo;
• Izikrokro zokuphulwa kobumfihlo bomsebenzisi kunye nezinye izenzo ezingekho mthethweni kwinxalenye yeenkonzo zomntu wesithathu.

Ukusungula i-CDN kuya kufuna ukuba ube negama lesizinda, iiseva ezininzi kwimimandla eyahlukeneyo (eyokwenene okanye ezinikeleyo) kunye nesixhobo sokucwangcisa isicelo. Musa ukulibala malunga nokufaka izatifikethi ze-SLL, ukuseta kunye nokuhlela iinkqubo zokukhonza umxholo we-static (i-Nginx okanye i-Apache), kunye nokubeka esweni ngokufanelekileyo yonke inkqubo.

Ulungelelwaniso oluchanekileyo lwe-caching proxies ngumxholo wenqaku elahlukileyo, ngoko asiyi kuchaza ngokweenkcukacha apha: apho kwaye yintoni iparameter yokuseta ngokuchanekileyo. Ukuqwalasela iindleko zokuqalisa kunye nexesha lokuhambisa inethiwekhi, ukusebenzisa izisombululo ezisele zilungile kunokuthembisa ngakumbi. Kodwa kuyimfuneko ukukhokelwa yimeko yangoku kwaye ucwangcise amanyathelo amaninzi ngaphambili.

Yintoni ekupheleni

I-CDN yiseti yezakhono ezongezelelweyo zokuhambisa itrafikhi yakho ebantwini. Ngaba ziyafuneka kwishishini le-Intanethi? Ewe kwaye hayi, konke kuxhomekeke kubaphi abaphulaphuli umxholo ojoliswe kubo kwaye zeziphi iinjongo umnini-shishini azenzayo.

Iiprojekthi zengingqi kunye nezikhethekileyo kakhulu ziya kufumana izinto ezingalunganga kuneenzuzo ezivela ekuphunyezweni kweCDN. Izicelo ziseza kuqala kumncedisi womthombo, kodwa ngomncedisi. Kungoko ukucutha okungathandekiyo kwiping, kodwa iindleko eziqinisekileyo zenyanga zokusebenzisa inkonzo. Ukuba unesixhobo esihle sothungelwano, unokuphucula ngokulula ii-algorithms zokhuseleko lolwazi, ubeke iiseva zakho kufutshane nabasebenzisi kwaye ufumane ukulungelelaniswa kunye neenzuzo simahla ngokuqhubekayo.

Kodwa ngubani onokuthi acinge malunga neeseva zangaphakathi ziinkampani ezinkulu ezineziseko zophuhliso ezingakwaziyo ukumelana nokukhula okuhamba rhoqo kwetrafikhi. I-CDN izibonisa ngokugqibeleleyo njengetekhnoloji ekuvumela ukuba ukhawuleze ukuhambisa inethiwekhi kwindawo ebanzi yabasebenzisi, ukubonelela ngemidlalo yamafu ekhululekile, okanye uthengise iimpahla kwiqonga elikhulu lezorhwebo.

Kodwa nangona kukho abaphulaphuli abaninzi bejografi, kubalulekile ukuqonda kwangaphambili ukuba kutheni uthungelwano lokuhanjiswa komxholo lufuneka. Ukukhawuleza kwewebhusayithi kusengumsebenzi onzima, ongenakho ukusonjululwa ngomlingo ngokuphumeza iCDN. Musa ukulibala malunga neempawu ezibalulekileyo ezinje: i-cross-platform, ukulungelelaniswa, ukulungiswa kwecandelo lomncedisi, ikhowudi, ukunikezelwa, njl. Uphicotho lokuqala lobugcisa kunye nemilinganiselo eyaneleyo yokuphelisa iingxaki isesona sisombululo sifanelekileyo kuyo nayiphi na iprojekthi ye-intanethi, kungakhathaliseki ukuba igxininise kangakanani kunye nesikali.

Njengentengiso

Ungaodola ngoku abancedisi abanamandlaabasebenzisa abaqhubekekisi bamva nje amd epyc. Izicwangciso eziguquguqukayo - ukusuka kwi-1 CPU core ukuya kwi-insane 128 CPU cores, i-512 GB RAM, i-4000 GB NVMe.
