• Scenario: Lets create a network to host ntier application with following subnets
  • web
  • app
  • db
  • management
• Solution:
  • We can create VPC using
    • Console
    • CLI
  • Console
    • Create a VPC with cidr 192.168.0.0/16
    • Create a
      • web subnet with 192.168.0.0/24
      • app subnet with 192.168.1.0/24
      • db subnet with 192.168.2.0/24
      • management subnet with 192.168.3.0/24
    • This vpc doesnt has access to internet, So create and attach internet gateway.
    • Now VPC has internet gateway, and a default route table, but they are not connected, so edit the routes and add route to destination 0.0.0.0/0 to internet gateway.
    • Now create a EC2 machine in web subnet and try to acess this
