Prerequisites

Prerequisites

ℹ️ Information: In this section, you will use CloudFormation templates to create a network infrastructure with internet connectivity, followed by launching two EC2 instances in the public subnets of two VPCs.

💡 Pro Tip: CloudFormation templates help automate the creation and management of AWS resources, saving time and reducing deployment errors.

🔒 Security Note: Ensure proper configuration of security groups and network ACLs to protect your resources.

VPC Peering Architecture

System Requirements

  1. AWS Account:

    • AWS account with access to VPC, EC2, and CloudFormation services
    • Sufficient quota for required resources

  2. Basic Knowledge:

    • Understanding of VPC and its components
    • Basic networking knowledge
    • Familiarity with AWS Management Console

  3. Required Tools:

    • Modern web browser
    • SSH client (PuTTY or MobaXterm)
    • Text editor for CloudFormation template modifications

Implementation Steps

  1. Initialize CloudFormation

    • Create VPC and basic network components
    • Configure Internet Gateway and NAT Gateway
    • Set up route tables

  2. Create Security Groups

    • Configure inbound rules for SSH and ICMP
    • Set up outbound rules
    • Apply security groups to instances

  3. Launch EC2 Instances

    • Launch EC2 instances in public subnets
    • Configure key pairs for SSH access
    • Test network connectivity

⚠️ Warning: Make sure to save all important information such as key pairs, security group IDs, and instance IDs for use in subsequent steps.
