Virtual Machine Scale Set (VMSS)

• Azure VMSS Refer Here
• Create a vmss quick start Refer Here
  
  
  
• Now change the size to 3
  
  
• Manually changing the numbers is not a good option in many cases, so lets make it scale according to some rules.
  • When cpu average > 80 increase 1 vm
  • When cpu average < 50 decrease 1 vm
  • Minimum number of instances = 1
  • Maximum number of instance = 5
    
    
    
    
    
    
• To test scaling we have installed a tool called as stress
• Exercise: Try autoscaling based on above rules and verify scale out and scale in
