AWS Networking

  • Global Infrastructure:

      • AZ’s: Availability Zones => Collection of Data Center Buildings

  • Networks in AWS are created using VPC (Virtual Private Cloud) which is a virtual network. VPC is scoped to a region & subnet is scoped to Availability Zone.
  • Virtual Devices (Virtual Machine, database) can be connected to the network via network interface which belongs to subnet.

  • Note: While learning networking never mess with default vpc.]
  • Every default vpc will have number of subnets equal to number of AZ’s
  • Lets create a vpc in mumbai region (which has 3 AZ’s) with 3 subnets
  • The cidr ranges to the vpc are always private cidr ranges.
    • Network CIDR: 192.168.0.0/22
    • subnet1 cidr: 192.168.0.0/24
    • subnet2 cidr: 192.168.1.0/24
    • subnet3 cidr: 192.168.2.0/24

  • Create a vpc in the oregon region with the four subnets in four az’s with any private cidr range. Ensure each subnet can connect to approximately 200 devices

    • Network range: 10.10.0.0/22
    • subnet1: 10.10.0.0/24
    • subnet2: 10.10.1.0/24
    • subnet3: 10.10.2.0/24
    • subnet4: 10.10.3.0/24
