작성자: microsoft

Azure API Management을 AI 게이트웨이로 구성하여 모델, MCP 도구, 에이전트에 내장된 거버넌스 정책을 적용합니다. 의미론적 캐싱(60-80% 비용 절감), 토큰 속도 제한, 콘텐츠 안전 필터링, AI 백엔드 전반의 탈옥 탐지를 지원합니다. Azure OpenAI, AI Foundry 모델을 추가하거나 기존 API를 MCP 도구로 변환하여 로드 밸런싱이 적용된 관리형 백엔드로 사용할 수 있습니다. 인증, 의미론적 캐시 조회, 토큰 제한, 콘텐츠 안전, 토큰 메트릭 등 다섯 가지 핵심 정책 범주를 포함합니다...

Azure AI Gateway

Configure Azure API Management (APIM) as an AI Gateway for governing AI models, MCP tools, and agents.

To deploy APIM, use the azure-prepare skill. See APIM deployment guide.

Get Gateway Details

# Get gateway URL
az apim show --name <apim-name> --resource-group <rg> --query "gatewayUrl" -o tsv

# List backends (AI models)
az apim backend list --service-name <apim-name> --resource-group <rg> \
  --query "[].{id:name, url:url}" -o table

# Get subscription key
az apim subscription keys list \
  --service-name <apim-name> --resource-group <rg> --subscription-id <sub-id>

Test AI Endpoint

GATEWAY_URL=$(az apim show --name <apim-name> --resource-group <rg> --query "gatewayUrl" -o tsv)

curl -X POST "${GATEWAY_URL}/openai/deployments/<deployment>/chat/completions?api-version=2024-02-01" \
  -H "Content-Type: application/json" \
  -H "Ocp-Apim-Subscription-Key: <key>" \
  -d '{"messages": [{"role": "user", "content": "Hello"}], "max_tokens": 100}'

Common Tasks

Add AI Backend

See references/patterns.md for full steps.

# Discover AI resources
az cognitiveservices account list --query "[?kind=='OpenAI']" -o table

# Create backend
az apim backend create --service-name <apim> --resource-group <rg> \
  --backend-id openai-backend --protocol http --url "https://<aoai>.openai.azure.com/openai"

# Grant access (managed identity)
az role assignment create --assignee <apim-principal-id> \
  --role "Cognitive Services User" --scope <aoai-resource-id>

Apply AI Governance Policy

Recommended policy order in <inbound>:

  1. Authentication - Managed identity to backend
  2. Semantic Cache Lookup - Check cache before calling AI
  3. Token Limits - Cost control
  4. Content Safety - Filter harmful content
  5. Backend Selection - Load balancing
  6. Metrics - Token usage tracking

See references/policies.md for complete example.


Troubleshooting

IssueSolution
Token limit 429Increase tokens-per-minute or add load balancing
No cache hitsLower score-threshold to 0.7
Content false positivesIncrease category thresholds (5-6)
Backend auth 401Grant APIM "Cognitive Services User" role

See references/troubleshooting.md for details.
