Azure VM Purchasing Options

  • Pay as you go:
    • In this purchasing you can create the VM’s on-demand and the billing will be applied as long as your vm’s are running.
  • Reservations:
    • Reservation is one-year or three year plans for multiple products in azure. This reservation can save the costs upto 72%
    • Payment modes are full upfront, partial upfront and pay as you go
  • Spot VM: Using Spot VMs allows us take advantage of unused capacity in azure regions with significant discounts. Here you can bid for spot vm’s for a particular price, when the vm is at or less that that price it will be allocated to you. Once the price increases the vm will be evicted.
