Geo-targeting content delivery with Akamai Property Manager

Question

Pulumi · Accepted Answer

To implement geo-targeting for content delivery with Akamai Property Manager, we'll use Pulumi with the Akamai provider. The Akamai Property Manager (APM) enables you to configure delivery settings for your websites, including how content is cached and delivered from Akamai's network. For geo-targeting specifically, we will focus on using the `akamai.Property` resource, which allows you to define and manage properties for your Akamai configurations.

In this context, geo-targeting refers to the method of distributing content to users based on their geographic location. You can use the Akamai Property Manager's rules to control this behavior by modifying delivery settings based on the `geo` criteria.

Here's how you might create an Akamai Property with Pulumi and TypeScript to implement geo-targeting:

- Define a new Akamai Property using `akamai.Property`.
- Specify the rules using Akamai's Property Manager Rules Language (PRL), which allows you to tailor the behavior for different geographic locations.
- The rules are defined as JSON objects, and you will insert a rule that examines the geography of incoming requests and alters caching or content delivery based on your requirements.

Let's create the Pulumi program to achieve this. Notice in the code comments how each relevant part contributes to the geo-targeting setup.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as akamai from "@pulumi/akamai";

// This is an example of a rule that performs geo-targeting. Modify this JSON structure
// to match your specific use case and targeting rules.
const geoTargetingRules = {
  rules: [
    {
      name: "Geo-Targeting-Example",
      criteria: [
        {
          name: "geo",
          options: {
            operation: "MATCHES_ONE_OF",
            values: ["US", "CA"] // Specify the geographies of interest here
          }
        }
      ],
      behaviors: [
        {
          name: "caching",
          options: {
            behavior: "MAX_AGE",
            ttl: "1d" // Set the cache time-to-live (TTL) for selected geographies
          }
        }
      ],
      // You can add more rules here for different geographic targets or other conditions
    }
  ]
};

// Create an Akamai Property to manage geo-targeted content delivery rules.
const akamaiProperty = new akamai.Property("myGeoTargetedProperty", {
    name: "example-geo-targeting",
    rules: JSON.stringify(geoTargetingRules), // Convert rule structure to a JSON string
    productId: "prd_SPM", // Specify your Akamai product ID (consult your contract)
    contractId: "ctr_1-ABCDE", // Your contract ID
    groupId: "grp_12345", // Your group ID
    ruleFormat: "latest", // Use the latest rule format that Akamai supports
    // additional properties such as hostnames, edgeHostnameId, etc., may be added here
});

// Export relevant outputs
export const propertyName = akamaiProperty.name;
export const propertyHostnames = akamaiProperty.hostnames;
```

In the above Pulumi program:

- We import the necessary modules (`pulumi` and `akamai`).
- We define our geo-targeting rules in a variable `geoTargetingRules`. In this specific block, we're creating a behavior based on geography that cache content for one day in the United States and Canada.
- An `akamai.Property` resource is instantiated, which encapsulates your desired configuration on the Akamai CDN. The `rules` attribute takes a JSON string that represents the setup for geo-targeting.
- We then export the property name and hostnames as outputs, which are useful identifiers for your deployment.

Please replace the placeholders (`"prd_SPM"`, `"ctr_1-ABCDE"`, `"grp_12345"`, and the content of `geoTargetingRules`) with actual values that correspond to your Akamai setup.

To apply this configuration, you would run `pulumi up` using the Pulumi CLI, after you have set up your Akamai provider credentials. The CLI walks you through the deployment process and shows you a preview of the changes before they are applied. Once you agree to proceed, Pulumi will configure your Akamai Property with the defined geo-targeting rules.

Remember, Akamai configurations can be complex, and these rules might require adjustment according to specific geo-targeting needs and your existing Akamai setup. Always refer to [Akamai's documentation](https://learn.akamai.com/en-us/webhelp/property-manager/property-manager-user-guide/GUID-FEB64018-D48A-4B2C-BD73-F92F8BCB0E97.html) for the specific syntax and capabilities of the Property Manager Rules Language.
