Spot nodepool, sport vm lerden olu\u015fan node’lar\u0131n olu\u015fturdu\u011fu vm pool’udur. Sport VM’lerin olu\u015fturdu\u011fu bu pool’u belli i\u015f y\u00fckleriniz i\u00e7in kullanarak belirgin \u00f6l\u00e7\u00fcde bir maliyet tasarrufu yapm\u0131\u015f olursunuz. Spot VM kullan\u0131m\u0131n\u0131 belirli fakt\u00f6rler etkiler. Bunlar kullan\u0131lan region, kullan\u0131lan vm size’\u0131, kullan\u0131lacak g\u00fcn gibi fakt\u00f6rlerdir.
Burada \u00f6nemli olan k\u0131s\u0131m \u015fu dur. Azure bu VM’ler i\u00e7in herhangi bir SLA vermemektedir. O anda o region i\u00e7erisindeki kapasitede sizin belirtti\u011finiz size’da bir availability varsa bu VM’leri d\u00fc\u015f\u00fck fiyatta kullanman\u0131za izin verir. AYr\u0131ca Spot kullan\u0131lan nodepool’lar arka planda ayn\u0131 fault domain i\u00e7erisinde tutulur. Bu da fiziksel olarak ya\u015fanacak bir sorunda t\u00fcm node’lar\u0131n etkilenece\u011fi anlam\u0131na gelir. Ayr\u0131ca herhangi bir high availability garantisi de verilmez.
Peki hangi tipte i\u015f y\u00fckleri i\u00e7in bu sport nodepool’lar uygun?
Genelde bu tipte i\u015f y\u00fckleri kesinti olmas\u0131 durumunda (Azure’un spot makineleri ihtiya\u00e7 duydu\u011funda geri almas\u0131 durumunda) herhangi bir sorun ya\u015famazlar. Bunlar;<\/p>\n\n\n\n
