1. Securing AI API Gateways with Cloudflare Access


    To secure an AI API Gateway with Cloudflare Access, you would typically deploy Cloudflare as a proxy in front of your API and then configure access policies to control who can access your API. Cloudflare Access acts as an identity-aware proxy that integrates with your identity provider and enables you to create access control policies based on user identity, group membership, and other criteria.

    To achieve this with Pulumi in Python, you would follow these steps:

    1. Create an Access Application: This resource defines the application that Cloudflare will protect. You need to specify the domain of your AI API Gateway and relate it to your Cloudflare zone.

    2. Configure Access Policy: It defines the rules that determine who can access your application. You need to provide details such as the zone ID, the application to protect, and the access control rules (includes, excludes, and requires).

    3. Set up Access Group (optional): If you need more granular control, you can define groups with specific access rules and tie them into your access policies.

    Below is a Pulumi program in Python that sets up an Access Application and configures an Access Policy to secure an AI API Gateway with Cloudflare Access. The specific configurations of the access policy would depend on your integration with your identity provider and your access control requirements.

    Before running this code, ensure you've installed the pulumi_cloudflare package and set up the Cloudflare provider with the necessary credentials.

    import pulumi import pulumi_cloudflare as cloudflare # Replace these variables with your domain, zone ID, and other relevant details. api_gateway_domain = "api.yourdomain.com" cloudflare_zone_id = "your-zone-id" # Create an Access Application for the AI API Gateway. access_app = cloudflare.AccessApplication("api-access-app", zone_id=cloudflare_zone_id, domain=api_gateway_domain, ) # Configure an Access Policy for the created application # Here, we're saying that only users from the group 'AI Team' can access the application. access_policy = cloudflare.AccessPolicy("api-access-policy", application_id=access_app.application_id, zone_id=cloudflare_zone_id, decision="allow", precedence=1, name="Allow AI Team Access", # 'Includes' define who is allowed based on identity providers, emails, IPs, etc. includes=cloudflare.AccessPolicyIncludesArgs( groups=["AI Team"], ), # 'Excludes' can be defined to deny access even if 'includes' are met. (optional) # 'Requires' can be defined to require additional checks like MFA. (optional) ) pulumi.export("access_application_name", access_app.name) pulumi.export("access_policy_name", access_policy.name)

    Before running the Pulumi program, sign in to the Cloudflare dashboard to obtain the zone ID for your domain and set your access policies according to your organization's requirements. In this example, I've added a placeholder group 'AI Team', which represents the group that should have access to the API Gateway. You will need to configure the appropriate group or access conditions that match your setup.

    Please note that this is a simplification, and real-world scenarios might require more complex configurations such as integrating with identity providers, setting up multifactor authentication, etc. Cloudflare Access allows quite a detailed and complex set of rules which are beyond the scope of a single example but can be implemented similarly by extending the AccessPolicyArgs parameters.
