          Her sanal makine, ana i\u015fletim sisteminin \u00fczerinde konuk i\u015fletim sistemine sahiptir. Container’lar ise izolasyon i\u00e7in farkl\u0131 bir yakla\u015f\u0131m\u0131 benimser: VM’ler gibi bir ana makine \u00fczerinde ya\u015famalar\u0131na ve onun kaynaklar\u0131n\u0131 kullanmalar\u0131na ra\u011fmen kendi i\u015fletim sistemlerine sahip olmalar\u0131 gerekmez, bir hipervisor (VMWare veya VirtualBox gibi) \u00e7al\u0131\u015ft\u0131rmay\u0131 gerektirmez bu da onlar\u0131n VM’lerden \u00e7ok daha hafif olmalar\u0131n\u0131 sa\u011flar.<\/p>\n\n\n\n

          Docker container’lar\u0131, tek bir i\u015fletim sistemi \u00fczerinde birden \u00e7ok uygulama \u00e7al\u0131\u015ft\u0131rmak istedi\u011finiz durumlar i\u00e7in uygundur. Ancak farkl\u0131 i\u015fletim sistemleriyle \u00e7al\u0131\u015fmas\u0131 gereken uygulamalar\u0131n\u0131z veya sunucular\u0131n\u0131z varsa, sanal makineler gereklidir.<\/p>\n\n\n\n

          Sanal makinelerde, ana bilgisayar \u00e7ekirde\u011finde g\u00fc\u00e7l\u00fc bir izolasyon s\u00f6z konusudur. Bu nedenle, VM’ler container’lara k\u0131yasla daha g\u00fcvenlidirler. <\/mark><\/p>\n\n\n\n

          Docker kaynaklar\u0131 payla\u015f\u0131ld\u0131\u011f\u0131 i\u00e7in, bir korsan\u0131n tek bir container’a eri\u015ferek k\u00fcmedeki t\u00fcm kapsay\u0131c\u0131lardan yararlanmas\u0131 s\u00f6z konusu olabilir. <\/p>\n\n\n\n

          Sanal makinelerden farkl\u0131 olarak, kaynaklar\u0131 kal\u0131c\u0131 olarak container’lara tahsis etmeye gerek yoktur. Container’lar\u0131 b\u00fcy\u00fctmek ve \u00e7o\u011faltmak, sanal makinelere k\u0131yasla kolayd\u0131r.<\/p>\n\n\n\n

          Docker container’lar\u0131 ayr\u0131 i\u015fletim sistemlerine sahip olmad\u0131klar\u0131 i\u00e7in kolayl\u0131kla ta\u015f\u0131nabilirler. Bir sanal makineyi ta\u015f\u0131mak, container’lara k\u0131yasla daha zordur. Uygulamalar\u0131n farkl\u0131 platformlarda geli\u015ftirilmesi ve test edilmesi gereken durumlar i\u00e7in Docker container’lar\u0131 idealdir.<\/p>\n\n\n\n

Container’lar ise mikro hizmetleri ve DevOps uygulamalar\u0131n\u0131 etkinle\u015ftirerek \u015firketlerin geli\u015ftirme kaynaklar\u0131ndan en iyi \u015fekilde yararlanmas\u0131na yard\u0131mc\u0131 olur.
