Hiperviz\u00f6r, konuk sistemin kaynak isteklerini fiziksel altyap\u0131yla e\u015fler. Konuk i\u015fletim sistemi sanal ayg\u0131tlar\u0131 kendi donan\u0131m\u0131 gibi kullan\u0131r. Ayg\u0131t s\u00fcr\u00fcc\u00fcleri, sanalla\u015ft\u0131rma uzant\u0131lar\u0131 ve y\u00f6netim katman\u0131 bu s\u00fcre\u00e7te g\u00f6rev al\u0131r; yap\u0131land\u0131rman\u0131n desteklenen s\u00fcr\u00fcmlerle uyumlu olmas\u0131 \u00f6nemlidir.<\/p>\n

Bir VM\u2019nin dosyas\u0131 veya imaj\u0131 ta\u015f\u0131nabilir bir paket olu\u015fturabilir; yine de her hiperviz\u00f6rde do\u011frudan \u00e7al\u0131\u015faca\u011f\u0131 varsay\u0131lmamal\u0131d\u0131r.

VM ile container aras\u0131ndaki fark<\/h2>\n

VM kendi konuk i\u015fletim sistemi \u00e7ekirde\u011fini \u00e7al\u0131\u015ft\u0131r\u0131r. Container yakla\u015f\u0131m\u0131nda s\u00fcre\u00e7ler genellikle ayn\u0131 ana sistem \u00e7ekirde\u011fini payla\u015fan izolasyon mekanizmalar\u0131yla \u00e7al\u0131\u015f\u0131r. Container\u2019lar bir VM\u2019nin i\u00e7inde de kullan\u0131labilir; iki teknoloji birbirini d\u0131\u015flamak zorunda de\u011fildir.<\/p>\n

Farkl\u0131 i\u015fletim sistemi gereksinimi, izolasyon s\u0131n\u0131r\u0131, a\u00e7\u0131l\u0131\u015f davran\u0131\u015f\u0131 ve y\u00f6netim ara\u00e7lar\u0131 se\u00e7imi etkiler. Bir uygulamay\u0131 container\u2019a almak onu otomatik olarak durumsuz veya g\u00fcvenli yapmaz. Benzer \u015fekilde VM kullanmak da uygulama g\u00fcncellemelerini, kimlik y\u00f6netimini ve a\u011f politikas\u0131n\u0131 kendili\u011finden \u00e7\u00f6zmez.<\/p>\n

Payla\u015f\u0131m modeli ve ana makine y\u00fck\u00fc \u00f6nemlidir. RAM ihtiyac\u0131n\u0131 yaln\u0131z ortalama t\u00fcketimle de\u011fil, yo\u011fun saatler ve uygulaman\u0131n cache davran\u0131\u015f\u0131yla \u00f6l\u00e7\u00fcn.<\/p>\n

Disk kapasitesi ile disk I\/O davran\u0131\u015f\u0131 farkl\u0131d\u0131r. Uygulaman\u0131n gecikme, i\u015flem say\u0131s\u0131 ve yazma tutarl\u0131l\u0131\u011f\u0131 ihtiyac\u0131n\u0131 belirleyin. A\u011fda da port h\u0131z\u0131, ger\u00e7ek aktar\u0131m, gecikme ve izinler ayr\u0131 kontrollerdir. Kaynak darbo\u011fazlar\u0131n\u0131 tek bir boyutu art\u0131rarak \u00e7\u00f6zmeye \u00e7al\u0131\u015fmak gereksiz maliyet olu\u015fturabilir.<\/p>\n
