Centralized Identity Management for AI Platforms on GCP

Question

Pulumi · Accepted Answer

Centralized identity management is a crucial aspect of secure access to various resources, and when it comes to Google Cloud Platform (GCP), one way to establish it is by using Google Cloud Identity Platform. The Identity Platform provides a suite of identity and user management services which can be used for authenticating and managing users within your applications.

In the context of AI platforms, you might be using services such as AI Platform Notebooks or Dialogflow, which are used to create machine learning models or conversational AI, respectively. To manage access to these services centrally, you can configure identity and access management (IAM) policies.

Let's build the management layer using Pulumi. We will define a GCP tenant for identity management and configure identity provider configurations for federated sign-in. While we won't be building the complete AI platform, we'll set up a tenant representing centralized identity management that can be integrated into various AI services.

Below you will find a Python program using Pulumi for setting this up:

- `Tenant`: This resource represents a tenant in the Identity Platform which will allow us to manage projects under a single umbrella of centralized identity.
- `TenantDefaultSupportedIdpConfig`: This configures a default identity provider for the tenant. You may configure multiple providers, but we'll use a single one as an example.

Here is how you would write a Pulumi program to achieve the above:

```python
import pulumi
import pulumi_gcp as gcp

# Initialize a new tenant for identity management.
# The tenant is essentially a secure, dedicated instance an identity provider, which provides
# you with a full suite of identity and access management functionality for your users.
tenant = gcp.identityplatform.Tenant("central_identity_management_ai_platform",
    display_name="Central Identity Management for AI Platform",
    disable_auth=False,
    allow_password_signup=True,
    enable_email_link_signin=False,
)

# Documentation: 
# https://www.pulumi.com/registry/packages/gcp/api-docs/identityplatform/tenant/

# Configure a default identity provider for the tenant.
# In a real-world scenario, you might configure various identity providers such as Google,
# Facebook, or any OpenID Connect (OIDC) compatible providers.
# The following example assumes you've already registered an OIDC provider and have the client ID
# and secret for connecting to that provider.

idp_config = gcp.identityplatform.TenantDefaultSupportedIdpConfig("default_idp_config",
    idp_id="google.com",
    tenant=tenant.name,
    enabled=True,
    # Replace with actual client ID and client secret obtained from the identity provider
    client_id="your-idp-client-id",
    client_secret="your-idp-client-secret",
)

# Documentation: 
# https://www.pulumi.com/registry/packages/gcp/api-docs/identityplatform/tenantdefaultsupportedidpconfig/

# Here we export the tenant name and default identity provider config name.
# These can be used to integrate with other GCP resources or services.
pulumi.export("tenant_name", tenant.name)
pulumi.export("default_idp_config_name", idp_config.name)
```

The above program sets up the infrastructure for centralized identity management on GCP. The Tenant resource initializes a tenant in the Identity Platform, which is a secure and dedicated instance for identity management for your applications on GCP.

The TenantDefaultSupportedIdpConfig specifies the default identity provider configurations for the tenant. In this program, we've used a placeholder for the client_id and client_secret which should be replaced with your actual credentials obtained when you register your application with the identity provider.

Remember to replace `your-idp-client-id` and `your-idp-client-secret` with actual values from your identity provider configurations.

After deploying this program with Pulumi, your GCP project will have a centralized identity management tenant configured, which you can integrate with AI and other services to manage user authentication and authorization. To deploy this Pulumi program, save the code to a file and run `pulumi up` after [setting up Pulumi and GCP](https://www.pulumi.com/docs/get-started/gcp/).
