Lesson Plan: AWS and DNS
Objective: Students will learn how to use Amazon Web Services (AWS) to set up a domain name system (DNS) and configure DNS records.
Materials:
AWS account Access to the AWS Management Console Basic understanding of DNS Prerequisites:
Basic knowledge of networking and DNS Familiarity with AWS Management Console Lesson Plan:
Introduction to AWS and DNS (10 minutes)
- Brief overview of AWS and its services
- Explanation of DNS and its importance in web applications
Setting up a DNS Zone (15 minutes)
- Log in to the AWS Management Console
- Navigate to Route 53 service
- Click "Create Hosted Zone"
- Enter a domain name and click "Create"
- Review the hosted zone details and take note of the nameservers
- Configuring DNS Records (25 minutes)
- Navigate to the hosted zone created in step 2
- Click "Create Record Set"
- Enter the record name, type, and value
- Click "Create"
- Repeat for additional records
- Test the records using a DNS lookup tool
Code Snippets (30 minutes)
- Provide students with code snippets for automating DNS record creation in AWS using the AWS SDK
- Guide students through setting up and configuring the SDK on their local machines
- Demonstrate how to use the SDK to create and modify DNS records Conclusion (10 minutes)
- Recap the importance of DNS in web applications
- Discuss the benefits of automating DNS record creation in AWS
- Encourage students to explore other AWS services and incorporate DNS in their future projects
Code Snippet: Here is an example of creating a DNS record in AWS Route 53 using the AWS SDK for Python:
import boto3
# Create a Route 53 client
client = boto3.client('route53')
# Define the hosted zone ID
hosted_zone_id = 'YOUR_HOSTED_ZONE_ID'
# Define the new record set
record_set = {
'Name': 'example.com',
'Type': 'A',
'TTL': 300,
'ResourceRecords': [
{
'Value': '192.0.2.1'
}
]
}
# Create the record set
response = client.change_resource_record_sets(
HostedZoneId=hosted_zone_id,
ChangeBatch={
'Changes': [
{
'Action': 'CREATE',
'ResourceRecordSet': record_set
}
]
}
)
# Print the response
print(response)
