Activity 4: Realize the below architecture in ARM

• Architecture
  
• Functions: Refer Here
• Refer Here for the changes done to create a vnet with 3 subnets
  
  
• Now lets add network security groups Refer Here
  • web: open 22,80 port from anywhere
  • business, data: default security groups (allow all internal communication)
• Refer Here for the changes done to add nsgs
  
• Lets create a network interface for web vm Refer Here for the changes done
• Now we need to add the linux vm in web subnet
