Ukusheshisa amakhasi akho wewebhu ngamakhodi okugcina nge-Caching Level Network
I-CDN imelela "Ukunikezwa Kwezokuqukethwe Okuqukethwe" futhi uhlelo lwekhompyutha olunezikripthi kanye nezinye okuqukethwe kuzo ezisetshenziswe kabanzi ngamakhasi amaningi ewebhu. I-CDN ingaba yindlela ephumelela kakhulu yokusheshisa amakhasi akho wewebhu ngoba okuqukethwe kuzolondolozwa kaningi kwi-node yenethiwekhi.
Indlela i-CDN isebenza ngayo
- Umklami wewebhu uxhumanisa kufayili kwi-CDN, njengesixhumanisi ku-jQuery.
- Ikhasimende livakashela elinye iwebhusayithi elisebenzisa i-jQuery.
- Ngisho noma kungekho omunye osebenzise leyo nguqulo ye-jQuery, uma ikhasimende lifika ekhasini ngenombolo 1, isixhumanisi ku-jQuery sesivele sigcinwe.
Kodwa kukhona okuningi kuwo. Amanethiwekhi wokuletha okuqukethwe aklanyelwe ukuba agcinwe kwizinga lenethiwekhi. Ngakho-ke, noma ngabe ikhasimende alihambeli elinye isayithi besebenzisa i-jQuery, amathuba ukuthi omunye umuntu onethiwekhi efanayo efanayo njengoba avuliwe uye wavakashela isayithi usebenzisa i-jQuery. Futhi ngakho le node ifihlile leyo sayithi.
Futhi noma yikuphi into efihliwe izolayisha kusuka kwesikhashana, esheshayo isikhathi sokulanda ikhasi.
Ukusebenzisa i-CDN yezohwebo
Amawebhusayithi amaningi amakhulu asebenzisa ama-CDN ezentengiselwano njengo-Akamai Technologies ukufihla amakhasi abo ewebhu emhlabeni jikelele. Iwebhusayithi esebenzisa i-CDN yezohwebo isebenza ngendlela efanayo. Ngesikhathi sokuqala ikhasi liceliwe, noma ubani, lakhiwe kusuka kuseva yewebhu. Kodwa-ke liphinde ligcinwe kwisiphakeli se-CDN. Khona-ke uma elinye ikhasimende lifika kuleli khasi elifanayo, kuqala i-CDN ihlolwe ukuze inqume ukuthi ngabe i-cache isesikhathini. Uma kunjalo, i-CDN iyayinikeza, ngaphandle kwalokho, iyayicela kusuka kuseva futhi namacaches okukopisha.
I-CDN yezohwebo iyithuluzi eliwusizo kakhulu kuwebhusayithi enkulu ethola izigidi zokubukwa kwekhasi, kepha kungenzeka ukuthi ingabi yindleko kumawebhusayithi amancane.
Ngisho namasayithi amancane angasebenzisa i-CDN yamaSkripthi
Uma usebenzisa noma yiliphi imilayibrari yeskriphthi noma izinhlaka ezisesayithini lakho, ukuzichaza ezivela kwi-CDN kungasiza kakhulu. Amanye amashayibhrari avame ukusetshenziswa asetshenziswa ku-CDN ahlanganisa:
- I-Chrome Frame
- I-Dojo Toolkit
- I-Ext JS
- jQuery
- I-jQuery UI
- I-MooTools
- I-prototype
- I-Script.actulous
- swfOkubhala
- I-Interface yomsebenzisi we-Yahoo (YUI)
Futhi i-ScriptSrc.net inikeza izixhumanisi kulezi zincwadi ngakho-ke akudingeki uzikhumbule.
Amawebhusayithi amancane angasebenzisa futhi ama-CDN wamahhala ukuze afihle okuqukethwe kwawo. Kukhona ama-CDN ambalwa ongawasebenzisa, kufaka phakathi:
- I-Cloudflare
- I-Coral CDN
- I-Traffic Server
Isikhathi sokushintshela kwinethiwekhi yokuletha okuqukethwe
Isikhathi sesikhathi sokuphendula sekhasi lewebhu sichithwa ukulandwa izingxenye zaleli khasi lewebhu, kufaka phakathi izithombe, amashidi, izitifiketi, i-Flash, njalonjalo. Ngokubeka eziningi zalezi zakhi ngangokunokwenzeka kwi-CDN, ungathuthukisa isikhathi sokuphendula ngokuphawulekayo. Kodwa njengoba ngishilo kungabiza ukusebenzisa i-CDN yokuthengisa. Ngaphezu kwalokho, uma ungaqapheli, ukufaka i-CDN kusayithi elincinci kunganciphisa, kunokuba liphuthume. Amabhizinisi amaningi amancane ayenqikazi ukwenza ushintsho.
Kukhona ezinye izinkomba ukuthi iwebhusayithi yakho noma ibhizinisi likhulu ngokwanele ukuzuza ku-CDN.
- Isayithi lakho lithola izivakashi eziningi nsuku zonke
- futhi lezo zivakashi zivela endaweni esatshalaliswe kabanzi
Abantu abaningi banomuzwa wokuthi udinga okungenani izivakashi eziyizigidi ngosuku ukuze uzuze ku-CDN, kodwa angicabangi ukuthi kunoma iyiphi inombolo ehleliwe. Isayithi elinezinqwaba zezithombe noma ividiyo ingazuza ku-CDN kulazo zithombe noma amavidiyo ngisho noma ukubukwa kwekhasi labo nsuku zonke liphansi kunezigidi. Ezinye izinhlobo zefayela ezingazuza ngokubanjwa kwi-CDN ziyizikripthi, i-Flash, amafayela aphilile, nezinye izakhi zekhasi le-static.
