Hosted zones concept in AWS - Mini Project: Build & Apply

Create a Private Hosted Zone in AWS Route 53

📖 Scenario: You are setting up a private network for your company's internal services. To manage domain names inside this private network, you will create a private hosted zone in AWS Route 53.

🎯 Goal: Build a private hosted zone in AWS Route 53 with a specific domain name and associate it with a VPC.

📋 What You'll Learn

Create a private hosted zone with the domain name internal.example.com

Associate the hosted zone with the VPC ID vpc-0abc123def456ghij

Set the hosted zone type to Private

Use AWS CLI commands or AWS SDK code snippets

💡 Why This Matters

🌍 Real World

Private hosted zones are used to manage DNS names inside a private network, such as a company's internal cloud environment, ensuring internal services are reachable only within the VPC.

💼 Career

Understanding hosted zones and VPC associations is essential for cloud engineers and network administrators managing AWS infrastructure and internal DNS.

1

Create the hosted zone data structure

Create a JSON object called hosted_zone_config with the key Name set to "internal.example.com" and the key CallerReference set to "unique-string-001".

AWS

# Create the hosted_zone_config JSON object
# Your code here

Need a hint?

The Name is the domain name for the hosted zone. The CallerReference is a unique string to identify the request.

2

Add the VPC association configuration

Add a key VPC to the hosted_zone_config dictionary. Set it to a dictionary with keys VPCRegion set to "us-east-1" and VPCId set to "vpc-0abc123def456ghij".

AWS

hosted_zone_config = {
    "Name": "internal.example.com",
    "CallerReference": "unique-string-001"
}
# Add the VPC association configuration below
# Your code here

Need a hint?

The VPC key links the hosted zone to the specific VPC by region and ID.

3

Add the hosted zone type configuration

Add a key HostedZoneConfig to hosted_zone_config. Set it to a dictionary with the key PrivateZone set to true.

AWS

hosted_zone_config = {
    "Name": "internal.example.com",
    "CallerReference": "unique-string-001",
    "VPC": {
        "VPCRegion": "us-east-1",
        "VPCId": "vpc-0abc123def456ghij"
    }
}
# Add HostedZoneConfig with PrivateZone true below
# Your code here

Need a hint?

Setting PrivateZone to true makes the hosted zone private to the VPC.

4

Complete the AWS CLI command to create the hosted zone

Write the AWS CLI command string create_command that uses aws route53 create-hosted-zone with the --name internal.example.com, --vpc VPCRegion=us-east-1,VPCId=vpc-0abc123def456ghij, and --hosted-zone-config PrivateZone=true options.

AWS

hosted_zone_config = {
    "Name": "internal.example.com",
    "CallerReference": "unique-string-001",
    "VPC": {
        "VPCRegion": "us-east-1",
        "VPCId": "vpc-0abc123def456ghij"
    },
    "HostedZoneConfig": {
        "PrivateZone": true
    }
}
# Write the AWS CLI command string create_command below
# Your code here

Need a hint?

This command creates the private hosted zone with the specified name, VPC association, and private zone setting.
