1. Public Gateway for OCI AI Services Integration

    Python

    To create a public gateway for Oracle Cloud Infrastructure (OCI) AI services integration, you'd typically need a way for clients outside of your virtual cloud network (VCN) to access your services. This can be achieved by setting up an API Gateway in OCI that serves as the entry point for all the incoming API requests, forwarding them to the appropriate backend services, such as OCI AI services.

    An API Gateway in OCI can help you provide a single point of entry for your public HTTP APIs, offer TLS termination, validate and authenticate requests, and throttle traffic to prevent abuse.

    Below, I explain how you can set up an API Gateway using Pulumi with Oracle Cloud Infrastructure (OCI).

    First, ensure you have the pulumi_oci package installed in your Python environment, which provides the necessary integrations with OCI.

    Then, in the Pulumi program:

    1. Define an instance of an API Gateway.
    2. Optionally, you can include other resources such as an Internet Gateway and attach it to your VCN if it's not already publicly accessible.
    3. Create an API Deployment which specifies the routes and backends for requests that reach the API Gateway.
    4. Finally, set up the security lists and routing rules to enable traffic to flow from the API Gateway to your service.

    The following Pulumi code provides an outline for setting up an API Gateway that integrates with OCI AI services:

    import pulumi import pulumi_oci as oci # Assuming you have an existing VCN and Subnet, replace <COMPARTMENT_ID>, <VCN_ID>, and <SUBNET_ID> # with the corresponding actual IDs from your OCI setup. compartment_id = "<COMPARTMENT_ID>" subnet_id = "<SUBNET_ID>" # Create an API Gateway in the given compartment and subnet. # The endpoint type 'PUBLIC' denotes this gateway will be accessible over the internet. api_gateway = oci.apigateway.Gateway("apiGateway", compartment_id=compartment_id, subnet_id=subnet_id, endpoint_type="PUBLIC", display_name="ai-services-api-gateway" ) # Create an API Deployment that targets the AI service backend. # You would define the route and backend configuration for the API request handling. # The 'specification' argument takes a document that describes the API deployment. api_deployment = oci.apigateway.Deployment("apiDeployment", compartment_id=compartment_id, gateway_id=api_gateway.id, specification={ # Specification details specifying the route and backend would be added here. # This is typically a JSON or YAML document following OpenAPI specifications # and would need to include the information for the AI services you're routing to. }, # Optional display name for the deployment display_name="ai-services-api-deployment" ) # Export the API Gateway endpoint URL so you can use it to make requests to your AI services. pulumi.export("api_gateway_url", api_gateway.endpoint_url)

    The code provided will set up a public API gateway that routes requests to the appropriate backend OCI AI services. You need to replace the placeholder IDs with the actual IDs from your OCI environment (<COMPARTMENT_ID> and <SUBNET_ID>). Also, to finalize the api_deployment resource, you will need to define the OpenAPI Specification (specification) document, which describes the API's routes, parameters, and backends.

    You can retrieve the API Gateway endpoint URL as an output from the Pulumi stack, and use that URL to invoke your publicly accessible API which is integrated with OCI AI Services.

    It is important to secure your API gateway properly by applying the necessary security policies and monitoring to ensure that only desired and authorized requests are processed by your AI services. You may also consider putting rate limiting and auditing in place as additional measures.
