1.4.2. The Universal Service Pattern

Every Azure AI service follows the same interaction pattern:

This means:

1. You create an Azure resource (which gives you an endpoint URL and API key)
2. Your application sends data to that endpoint
3. The service returns predictions in a structured format (usually JSON)

Why This Matters for the Exam:

When a question asks about using any Azure AI service, the answer always involves creating a resource, obtaining credentials, and calling the API. The specific service names change, but the pattern remains constant.
