Bir CDN'i yap\u0131land\u0131rmak genellikle birka\u00e7 temel ad\u0131m\u0131 izler: \u00d6ncelikle, h\u0131zland\u0131r\u0131lmas\u0131 gereken alan ad\u0131n\u0131 CDN servis sa\u011flay\u0131c\u0131s\u0131n\u0131n konsoluna ekleme.

S\u0131k\u00e7a Sorulan Sorular.<\/h2>\n\n\n\n

CDN ve bulut sunucusu aras\u0131ndaki fark nedir?<\/h3>\n\n\n\n

CDN (Content Delivery Network) ve bulut sunucular\u0131 (cloud servers), farkl\u0131 ancak birbirini tamamlayan iki hizmettir. Bulut sunucular\u0131, uygulamalar\u0131n hesaplanmas\u0131, depolanmas\u0131 ve \u00e7al\u0131\u015ft\u0131r\u0131lmas\u0131 i\u00e7in gerekli ortam\u0131 sa\u011flar ve i\u00e7eri\u011fin \u201c\u00fcretim merkezi\u201d veya \u201cana sunucusu\u201d g\u00f6revini g\u00f6r\u00fcr. CDN ise i\u00e7eri\u011fin da\u011f\u0131t\u0131m a\u011f\u0131d\u0131r; i\u00e7erik \u00fcretmez, ancak bulut sunucular\u0131ndaki (veya herhangi bir ana sunucudaki) i\u00e7eri\u011fi kopyalar ve d\u00fcnya genelindeki \u00f6nbellek (cache) noktalar\u0131na da\u011f\u0131t\u0131r. CDN\u2019nin amac\u0131, eri\u015fim h\u0131z\u0131 sorunlar\u0131n\u0131 \u00e7\u00f6zmektir.<\/p>\n\n\n\n

CDN kullan\u0131ld\u0131ktan sonra, web sitesinin orijinal sunucusuna hala ihtiya\u00e7 var m\u0131?<\/h3>\n\n\n\n

Evet, h\u00e2l\u00e2 gereklidir. Orijinal sunucu, yani kaynak sunucu, i\u00e7eri\u011fin nihai kayna\u011f\u0131 ve yetkili veri depolama yeridir. CDN (Content Delivery Network \u2013 \u0130\u00e7erik Da\u011f\u0131t\u0131m A\u011f\u0131) kenar d\u00fc\u011f\u00fcmlerinde saklananlar sadece kopyalard\u0131r. Kullan\u0131c\u0131 taraf\u0131ndan istenen i\u00e7erik kenar d\u00fc\u011f\u00fcmde bulunmuyorsa (cache hit olmam\u0131\u015fsa) veya cache s\u00fcresi dolmu\u015fsa, kenar d\u00fc\u011f\u00fcm yine de en yeni i\u00e7eri\u011fi kaynak sunucudan \u00e7ekmek zorundad\u0131r. Ayr\u0131ca, cache edilemeyen veya edilmemesi gereken dinamik i\u00e7erikler, kullan\u0131c\u0131 giri\u015f durumu gibi istekler de do\u011frudan kaynak sunucudan i\u015flenir.<\/p>\n\n\n\n

CDN, dinamik i\u00e7erikleri h\u0131zland\u0131rabilir mi?<\/h3>\n\n\n\n

Tabii ki. Geleneksel CDN\u2019ler esas olarak statik i\u00e7erikleri h\u0131zland\u0131r\u0131r, ancak modern CDN\u2019ler ak\u0131ll\u0131 y\u00f6nlendirme teknolojileri sayesinde dinamik i\u00e7erikleri de h\u0131zland\u0131rabilir. Bu i\u015flemin prensibi, dinamik yan\u0131tlar\u0131 \u00f6nbelle\u011fe almaktan ziyade (\u00e7\u00fcnk\u00fc her istek farkl\u0131 olabilir), kullan\u0131c\u0131 ile kaynak sunucu aras\u0131ndaki a\u011f ba\u011flant\u0131s\u0131n\u0131 optimize ederek daha iyi ve daha stabil bir yol se\u00e7mek, a\u011f gecikmelerini ve paket kayb\u0131n\u0131 azaltmak ve b\u00f6ylece dinamik isteklerin yan\u0131t h\u0131z\u0131n\u0131 art\u0131rmakt\u0131r. Buna genellikle \u201cdinamik h\u0131zland\u0131rma\u201d veya \u201cy\u00f6nlendirme optimizasyonu\u201d denir.<\/p>\n\n\n\n

Bir CDN'yi yap\u0131land\u0131rmak, bir web sitesinin SEO s\u0131ralamas\u0131n\u0131 etkiler mi?<\/h3>\n\n\n\n

Do\u011fru \u015fekilde yap\u0131land\u0131r\u0131lm\u0131\u015f bir CDN, SEO\u2019yu zarar vermek yerine olumlu etkiler. Google gibi arama motorlar\u0131, web sitelerinin y\u00fckleme h\u0131z\u0131n\u0131 \u00f6nemli bir s\u0131ralama fakt\u00f6r\u00fc olarak de\u011ferlendirir. CDN, web sitesi eri\u015fim h\u0131z\u0131n\u0131 \u00f6nemli \u00f6l\u00e7\u00fcde art\u0131rarak arama motoru botlar\u0131n\u0131n veri toplama verimlili\u011fini iyile\u015ftirir ve kullan\u0131c\u0131 deneyimini geli\u015ftirir; bu da SEO a\u00e7\u0131s\u0131ndan faydal\u0131d\u0131r.
