1. Deploying AI-Based Content Personalization with Cloudflare Workers


    Deploying AI-based content personalization using Cloudflare Workers involves setting up serverless functions that run at Cloudflare's edge locations. Cloudflare Workers enable you to customize how content is served based on factors such as user location, device type, cookies, and more. The serverless nature means you don't manage infrastructure, but rather focus on the code that powers your personalization logic.

    In this Pulumi Python program, we will deploy a Cloudflare Worker script and configure a Worker route to trigger the execution of the script when certain patterns of requests are matched.

    We will perform the following steps:

    1. Implement a simple personalization logic in a Cloudflare Worker script.
    2. Deploy the Worker script to Cloudflare.
    3. Define a Worker Route pattern that will trigger the execution of the deployed script.
    4. Use a Workers KV (Key-Value) store if our AI logic requires storing and retrieving any data.

    Here's the program that accomplishes this:

    import pulumi import pulumi_cloudflare as cloudflare # Configuration: put your Cloudflare account ID here cloudflare_account_id = 'your-account-id' # Cloudflare Worker JavaScript code as an example # This code simply personalizes content based on the visitor's country # In a real-world scenario, you might call AI APIs or use more complex logic worker_code = """ addEventListener('fetch', event => { event.respondWith(handleRequest(event.request)) }) async function handleRequest(request) { // Example: Personalize content based on country header provided by Cloudflare const country = request.headers.get('CF-IPCountry') let personalizedContent = `Welcome visitor from ${country}!` return new Response(personalizedContent, {status: 200}) } """ # Deploy a Cloudflare Worker script worker_script = cloudflare.WorkerScript("ai-content-personalization", name="ai-content-personalization", content=worker_code, account_id=cloudflare_account_id, # Your Cloudflare Account ID ) # Define a Worker Route to trigger the Worker script on specific pattern(s) worker_route = cloudflare.WorkerRoute("ai-content-personalization-route", pattern="example.com/*", # Update with your domain and desired pattern script_name=worker_script.name, zone_id="your-zone-id", # Your Cloudflare Zone ID where the domain is managed ) # Export the Worker script name and the route pattern for easy access pulumi.export('worker_script_name', worker_script.name) pulumi.export('worker_route_pattern', worker_route.pattern)

    In the program above:

    • We begin by importing Pulumi and the Cloudflare Pulumi package.
    • We then define the cloudflare_account_id variable, which should be set to your Cloudflare account ID.
    • The worker_code variable stores the JavaScript code that personalizes content. Real-world personalization logic can be used here, potentially involving calling external AI APIs.
    • The cloudflare.WorkerScript resource deploys the JavaScript code to Cloudflare Workers.
    • The cloudflare.WorkerRoute resource configures which requests should trigger the worker's execution based on a URL pattern.

    Please replace your-account-id, example.com/*, and your-zone-id with your actual Cloudflare account ID, the domain/pattern you wish to match, and your Cloudflare zone ID respectively.

    Finally, the script's name and route pattern are exported for reference, which can be retrieved from the Pulumi stack's output after deployment.
