Empowering AI: Building and Deploying Azure AI Landing Zones with Terraform

philipstreet2023   Thanks for your remarks, according to my experience when the backend base URL includes the "privatelink" subdomain, it indicates that the OpenAI backend service is accessed via a private endpoint. This means the service is isolated from the public internet, offering enhanced security and restricting access to only authorized networks or virtual networks within Azure. 

On the other hand, using the ".openai.azure.com" domain without "privatelink" in the backend base URL implies that the OpenAI backend service is reachable via a public endpoint. This configuration allows the service to be accessed from any location on the internet, just like any other publicly available website or service. Public endpoints are suitable for applications that don't require strict access control or need to be accessed by a wider audience.

The decision to choose a private or public endpoint for the OpenAI backend service depends on the specific security requirements and nature of the application. If data privacy and stringent security measures are essential, a private endpoint with "privatelink" is recommended.

I might have misunderstood your remark, please don't hesitate to elaborate or provide more details if it is the case.

Thank you
