Azure AI-200 glossary of AI app architecture, orchestration, and governance terms.
Use this glossary when Microsoft AI Cloud Developer route (AI-200) terms start to blur together. The goal is practical recognition, not encyclopedia coverage.
| Term | Exam meaning |
|---|---|
| Serverless function | Event-driven compute that runs code without managing servers directly. |
| Event-driven architecture | A design where producers emit events and consumers react asynchronously. |
| Vector search | Similarity search over embeddings, often used to retrieve context for generative AI. |
| Managed identity | Credential-free identity for Azure resources calling other Azure services. |
| Telemetry | Logs, metrics, traces, and events used to operate and troubleshoot an application. |
| Idempotency | A design property where repeated processing of the same request does not corrupt state. |
| Pair | How to separate them |
|---|---|
| Application hosting vs Integration and events | Ask which layer the scenario is testing, then match the answer to that layer only. |
| Control vs evidence | A control changes behavior; evidence proves behavior or supports investigation. |
| Managed service vs custom build | Managed services win for lower operational effort unless the requirement needs unsupported customization. |
| Prevention vs detection | Prevention blocks or reduces a bad event; detection finds or reports that it happened. |
Do not memorize terms in isolation. For each term, write one scenario where it is the best answer, one scenario where it is a distractor, and one signal that proves it worked.
