Azure VM States

• Azure VM States
• Starting:
  • VM is Starting up.
  • In this state you will not be billed for vm usage
• Running:
  • Working State of VM
  • In this state you will be billed for vm usage
• Stopping State:
  • This is a transitional state. When it is completed it will show as Stopped
  • In this state you will be billed for vm usage
• Stopped:
  • VM has been shut down but Hardware is still allocated to the VM
  • In this state you will be billed for vm usage
• Deallocating:
  • This is a tranisitional State. When it is completed you will be in deallocated stated

• Deallocated:
  • VMI is stopped and removed from the physical host

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.
• Lets create a Price Estimate for a compute optimized instance with 4 vcpus running Windows 2016 and memory optimized linux vm with 16 GB of RAM
  • Pay As you go
  • 1 year reserved
  • 3 years reserved
• Spot VM Creation
• Exercise-1:
  • Create an estimate for running 10 storage optimized linux vm’s with 4vcpu and atleast 8 GB of RAM
    • Pay as you go
    • 3-years reserved
• Exercise-2:
  • Create an excel estimate for the architecture depicted below
