Azure VNet Contd

  • Lets create a virtual network in a region

  • We will be having 4 subnets
    • web:
    • app:
    • db:

  • When we try to create a vm in one of the subnets a nic is created. There will generally be Network Security Group attached to nic.
  • If we need to access publically, then the nic will be associated with public ip address
  • Now lets try to create a free azure vm with focus on networking
  • Now lets focus on networking blade of Azure VM
  • Now we were able to ssh into vm
ssh <username>@<publicip>
  • We have checked the vm gets internet
