Creating Your Amazon VPC

ℹ️ What is Amazon VPC?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources in a logically isolated virtual network that you define. This virtual network closely resembles a traditional network with the benefits of using AWS’s scalable infrastructure.

Step-by-Step VPC Creation

  1. Access the AWS Management Console:
    • Navigate to the VPC service
    • Select Your VPCs from the left navigation panel

Create VPC

  1. Initiate VPC creation:
    • Click on Create VPC button in the top-right corner

Create VPC

  1. Configure your VPC settings:
    • Under Resources to create, select VPC only
    • Enter Name tag: ASG
    • Set IPv4 CIDR block: 10.10.0.0/16 (providing 65,536 IP addresses)

ℹ️ CIDR Block Information
The 10.10.0.0/16 CIDR block is part of the RFC 1918 private address space (10.0.0.0/8), making it suitable for private networks and ensuring no conflicts with public internet addresses.

⚠️ Warning
For the Tenancy setting, it’s recommended to keep the Default option. Selecting Dedicated tenancy may limit which EC2 instance types you can launch within this VPC, as some instance types require default tenancy.

  1. Complete the VPC creation:

    • Click Create VPC

💡 Pro Tip
When planning your VPC CIDR block, consider your current and future IP address needs. The CIDR block cannot be changed after the VPC is created, so choose a size that accommodates growth while avoiding unnecessary overlap with other networks you might connect to later.
