  • [AWS] Launch the VPC Wizard

    Let's learn how to create your custom VPC. From the VPC Dashboard, click the Launch VPC Wizard. It is a two-step process, as mentioned below.

    Snapshot 1. Launch the VPC Wizard, and select one of the pre-defined network structure.

    Step 1: Network Structure

    Select the Network Structure from the options below:

    • VPC with a Single Public Subnet
    • VPC with Public and Private Subnets
    • VPC with Public and Private Subnets and Hardware VPN Access
    • VPC with a Private Subnet Only and Hardware VPN Access

    Snapshot 2. Specify the VPC configuration

    Step 2: Specify the VPC configuration

    The VPC configuration includes:

    • The IP address in the VPC follows a classless inter-domain routing (CIDR) block of IP addresses. You will have to specify the IPv4/IPv6 CIDR block to be allocated to the VPC. In the snapshot above, it uses an IPv4 10.0.0.0/16 block, which allocates 2^(32-16) = 65,536 IP addresses. A few IP addresses are reserved, so you get 65531 IP addresses for further allocation.

    • You will have to specify the range of IP address from the allocated CIDR block for each subnet. In the example above, the public subnet has been allotted the 10.0.0.0/24 range, which comprises 2^(32-24) = 256 IP addresses. But, again a few IP addresses are reserved, so you get 251 available for resources in that subnet.

    • Similarly, for the private subnet in the snapshot above, you will get 251 IP addresses.
    • Specify the AZ for each subnet, NAT gateway or elastic IP allocation ID, and the service endpoints that will allow you to privately connect your VPC to supported AWS services.
