Bug\u00fcnlerde sanalla\u015ft\u0131rma ve konteyner teknolojileri hakk\u0131nda etrafta olduk\u00e7a fazla bilgi var. Bu kavramlara basit olarak bir a\u00e7\u0131klama getirmek ve konuyu merak edenlere bir ba\u015flang\u0131\u00e7 noktas\u0131 sunmak isteriz.\u00a0<\/span><\/p>\n

Sanalla\u015ft\u0131rma\u00a0<\/strong><\/span><\/h2>\n

\u0130ki tip sanalla\u015ft\u0131rma vard\u0131r. Tip 1 donan\u0131m ile aras\u0131nda herhangi bir katman olmadan donan\u0131m\u0131n hypervisor \u00f6zelli\u011fi kullan\u0131larak bir sanalla\u015ft\u0131rma ve tip 2 ise host i\u015fletim sistemi \u00fczerinde kullan\u0131larak sanalla\u015ft\u0131rmad\u0131r.<\/span><\/p>\n

Sanalla\u015ft\u0131rma, sadece bir i\u015fletim sisteminin izolasyonunu sa\u011flayarak sanalla\u015ft\u0131rma ger\u00e7ekle\u015ftirmez. Yan\u0131nda gerekli olan disk, network gibi donan\u0131mlar\u0131n sanalla\u015ft\u0131rmas\u0131n\u0131 da ger\u00e7ekle\u015ftirerek sanalla\u015ft\u0131rma i\u015flemini yapar.

Konteyner<\/strong><\/h2>\n

Konteynerler, hypervisorler kadar eski bir teknoloji de\u011fil. Docker bu kadar \u00fcnl\u00fc olmadan \u00f6nce LXC (Linux Containers) servisleriyle Docker’\u0131n yapt\u0131\u011f\u0131 \u00e7o\u011fu i\u015fi yapabiliyorduk. Zaten Docker’da DotCloud olarak ilk ismine sahip LXC\u2019ye yap\u0131lm\u0131\u015f eklentilerden ibaretti. Peki \u2018Docker, LXC’nin yapamad\u0131\u011f\u0131 ne yapt\u0131 da bu kadar \u00fcnl\u00fc oldu ?\u2019 derseniz, bu sorunun cevab\u0131n\u0131 a\u015fa\u011f\u0131daki listede bulabilirsiniz :<\/span><\/p>\n
