Azure vnet contd

• In Azure subnet is scoped to Region
  
• In the same subnet as shown above we can have vms from different zones.
• Lets create a linux vm and connect it the network created in last session
  
  
  
  
  
  
• The componets with relevance to network created are
  • Network security Group
  • Network Interface
  • Public Ip Address
• Connect to the linux machine from your system using public ip

ssh username@publicip
sudo apt install net-tools
ifconfig

* Lets have a look at public ip address created


* Lets have a look at network interface

* Lets have a look at network security group

Scenario – 1

• Create a virtual network in any region (/22) with 3 subnets
  • web (/24)
  • app (/24)
  • db (/24)
    
    
• Create a linux vm with public ip address in web subnet
  
• create a linux vm without public ip address in app subnet
  
• Lets try to connect to the app server from our laptop
  • direct connection is not possible as app server doesnot have public ip
  • so lets connect to web server and from webserver lets connect to app server as communication with in vnet is enabled by default (private connections)
