Subdomain Setup for AI Model Versioning

Question

Pulumi · Accepted Answer

To set up a subdomain for AI model versioning, you'll typically use a combination of DNS management and possibly some form of api-gateway or function trigger, depending on your exact requirements. I'll demonstrate how to create a subdomain using AWS Route 53 to manage DNS records, which is a common setup for versioning since it allows you to map different subdomains to different endpoints or resources, such as different versions of your AI model.

In this program, we'll use Pulumi's AWS provider to create a Route 53 record which will point to an AWS resource, such as an API Gateway that would serve as an endpoint for your AI model. We won't be setting up the actual AI model serving system, as that would depend heavily on what kind of infrastructure you're using to host and serve your model.

Here's a program that sets up a subdomain for model versioning:

```python
import pulumi
import pulumi_aws as aws

# Set up a reference to your existing hosted zone for your domain.
# A hosted zone for the domain `example.com` should already be set up.
# Replace `example_com_zone_id` with your actual hosted zone ID.
hosted_zone_id = "example_com_zone_id"
hosted_zone = aws.route53.get_zone(id=hosted_zone_id)

# This Record will create a subdomain pointing to an example AWS resource.
# In this case, let's say it is an API Gateway for the v1 version of your model.
record_v1 = aws.route53.Record("api-v1",
    zone_id=hosted_zone.zone_id,
    name="v1.api.example.com",  # Replace with your desired subdomain.
    type="A",
    aliases=[
        aws.route53.RecordAliasArgs(
            name="example-api-gateway-url.amazonaws.com",
            zone_id="ZLY8HYME6SFAD",  # This is typically the zone ID for an API Gateway.
            evaluate_target_health=True,
        ),
    ]
)

# Output the subdomain URL
pulumi.export("subdomain_v1", record_v1.fqdn)
```

In the above program, we create a DNS record (`aws.route53.Record`) for the subdomain `v1.api.example.com`. We assume you have a hosted zone for `example.com` in Route 53 and an existing API Gateway setup which serves an AI model. The `aliases` argument is used to point the subdomain to the API Gateway with an A record. The `zone_id` for the alias should be set to the zone ID of the API Gateway service (typically fixed for the service, but check your specific AWS region just in case).

The Route 53 record is automatically set up to route requests for `v1.api.example.com` to the API Gateway endpoint. You can replicate the `aws.route53.Record` section for other versions of the API, such as `v2.api.example.com` and so on, pointing each to their respective resources.

Please make sure to replace `example_com_zone_id`, `example.com`, and `example-api-gateway-url.amazonaws.com` with your domain's actual Route 53 Hosted Zone ID, domain name, and the API Gateway endpoint URL respectively.

Remember to check the exact values relevant to your AWS resources ("Zone ID" for your API Gateway and the hosted zone ID for your domain). Also, the above program assumes that you have the Pulumi AWS provider configured and you are authenticated against AWS with the necessary permissions.
