AI Search services, including Azure AI Search, use HTTPS over TCP when accessing resources such as OpenAI Service or Azure Blob Storage. In particular:

Accessing OpenAI Service: AI Search uses HTTPS over TCP to interact with the OpenAI API. HTTPS ensures encrypted communication, maintaining data security and confidentiality during transmission. TCP provides reliable packet delivery. The RESTful API endpoints provided by OpenAI are accessed using HTTPS, which is standard for such integrations.

Accessing Azure Blob Storage: Similarly, HTTPS over TCP is used to access Azure Blob Storage. This ensures secure data transfer between AI Search and Blob Storage, whether for indexing, storing, or retrieving data. Azure Storage services enforce HTTPS by default to secure all communications.

There are several reasons for using HTTPS over TCP:

Security: Encryption via HTTPS prevents eavesdropping and data breaches.
Reliability: TCP ensures that all data packets are delivered in order and without errors, essential for high-availability services like AI Search.
Compliance: Using HTTPS complies with security standards and regulations like GDPR and HIPAA.

Marcin, thank you for your answer.
Is the API endpoint unchanged whether accessed by a user or another resource?

Yes, the API endpoint remains the same whether accessed by a user or another resource. For example:

OpenAI Service:

The API endpoint for OpenAI (e.g., https://api.openai.com/v1/...) does not change based on the caller. Both human users (via tools or scripts) and other resources (like AI Search or Azure functions) use the same endpoint.

Access control and permissions are managed through API keys or Azure role-based access control (RBAC), not by changing endpoints.

Azure Blob Storage:

The REST API endpoint for accessing Azure Blob Storage remains the same, regardless of whether the request is made by a user or a resource. For example, the endpoint format like https://<storage-account-name>.blob.core.windows.net/<container-name>/<blob-name> is constant.

Authentication can vary (Shared Key, SAS token, OAuth, or managed identities), but the endpoint structure stays consistent.
