Subdomain Setup for Model Deployment Services

Introduction

This guide will walk you through the process of setting up subdomains for model deployment services using Pulumi with AWS. We will create an S3 bucket to host the static content, configure a CloudFront distribution for content delivery, and set up Route 53 for DNS management.

Step-by-Step Explanation

Step 1: Create an S3 Bucket

First, we need to create an S3 bucket to host the static content for our model deployment services.

import * as aws from "@pulumi/aws";

const bucket = new aws.s3.Bucket("model-deployment-bucket", {
    website: {
        indexDocument: "index.html",
    },
});

Step 2: Configure CloudFront Distribution

Next, we will set up a CloudFront distribution to deliver the content from the S3 bucket.

const cdn = new aws.cloudfront.Distribution("cdn", {
    origins: [{
        domainName: bucket.websiteEndpoint,
        originId: bucket.arn,
    }],
    enabled: true,
    isIpv6Enabled: true,
    defaultRootObject: "index.html",
    defaultCacheBehavior: {
        allowedMethods: ["GET", "HEAD"],
        cachedMethods: ["GET", "HEAD"],
        targetOriginId: bucket.arn,
        viewerProtocolPolicy: "redirect-to-https",
        forwardedValues: {
            queryString: false,
            cookies: { forward: "none" },
        },
    },
    priceClass: "PriceClass_100",
    restrictions: {
        geoRestriction: {
            restrictionType: "none",
        },
    },
    viewerCertificate: {
        cloudfrontDefaultCertificate: true,
    },
});

Step 3: Set Up Route 53

Finally, we will configure Route 53 to manage the DNS records for our subdomain.

const zone = new aws.route53.Zone("model-deployment-zone", {
    name: "example.com",
});

const record = new aws.route53.Record("model-deployment-record", {
    zoneId: zone.id,
    name: "models.example.com",
    type: "A",
    aliases: [{
        name: cdn.domainName,
        zoneId: cdn.hostedZoneId,
        evaluateTargetHealth: false,
    }],
});

Summary

In this guide, we created an S3 bucket to host static content, set up a CloudFront distribution for content delivery, and configured Route 53 to manage DNS records for our subdomain. This setup ensures that our model deployment services are accessible via a custom subdomain with high availability and performance.

Full Code Example

import * as aws from "@pulumi/aws";

// Step 1: Create an S3 Bucket
const bucket = new aws.s3.Bucket("model-deployment-bucket", {
    website: {
        indexDocument: "index.html",
    },
});

// Step 2: Configure CloudFront Distribution
const cdn = new aws.cloudfront.Distribution("cdn", {
    origins: [{
        domainName: bucket.websiteEndpoint,
        originId: bucket.arn,
    }],
    enabled: true,
    isIpv6Enabled: true,
    defaultRootObject: "index.html",
    defaultCacheBehavior: {
        allowedMethods: ["GET", "HEAD"],
        cachedMethods: ["GET", "HEAD"],
        targetOriginId: bucket.arn,
        viewerProtocolPolicy: "redirect-to-https",
        forwardedValues: {
            queryString: false,
            cookies: { forward: "none" },
        },
    },
    priceClass: "PriceClass_100",
    restrictions: {
        geoRestriction: {
            restrictionType: "none",
        },
    },
    viewerCertificate: {
        cloudfrontDefaultCertificate: true,
    },
});

// Step 3: Set Up Route 53
const zone = new aws.route53.Zone("model-deployment-zone", {
    name: "example.com",
});

const record = new aws.route53.Record("model-deployment-record", {
    zoneId: zone.id,
    name: "models.example.com",
    type: "A",
    aliases: [{
        name: cdn.domainName,
        zoneId: cdn.hostedZoneId,
        evaluateTargetHealth: false,
    }],
});

// Export relevant URLs
export const bucketEndpoint = bucket.websiteEndpoint;
export const cdnDomainName = cdn.domainName;
export const zoneName = zone.name;
