✨ AI Gateway Labs

Explore the enterprise-grade gateway for managing AI Models, Tools, and Agents

📰 New! The AI Gateway Dev Portal is now live — A starting point for building your own developer portal on top of Azure API Management AI Gateway's. Fork it, open it in VS Code with GitHub Copilot (or any coding agent), and shape it to fit your needs!

Why AI Gateway?

Building production-ready AI applications requires more than just calling model APIs. You need security, reliability, observability, and cost control—without slowing down innovation.

AI Gateway powered by Azure API Management provides:

• 🔐 Security — OAuth 2.0, managed identities, content safety filtering
• ⚡ Performance — Load balancing, semantic caching, request routing
• 📊 Observability — Token metrics, built-in logging, tracing
• 💰 Cost Control — Rate limiting, quota management, FinOps framework
• 🔌 Extensibility — MCP protocol support, function calling, multi-model routing

📚 Explore the Labs

🔗 Browse all 30+ labs at aka.ms/ai-gateway/labs

Each lab is a hands-on Jupyter notebook with step-by-step instructions, Bicep infrastructure templates, and APIM policies you can deploy to your Azure subscription.

👩‍💻 Build Your Own Labs with AI

This repository includes Copilot Agent Skills that help you create new labs using AI-assisted development in VS Code.

Available Skills

| Skill | Description | |-------|-------------| | lab-creator | Scaffolds new labs with notebooks, Bicep, and policies | | apim-bicep | Generates Azure Bicep templates for APIM resources | | apim-terraform | Generates Terraform configurations for APIM | | apim-policies | Creates APIM XML policies for AI gateway scenarios | | apim-kql | Generates queries in KQL to control models, tools and agents | | mcp-builder | Builds MCP servers for tool integration |

Example: Create a New Lab

Open this repo in VS Code with GitHub Copilot and use this prompt:

Create a new lab called "multi-model-failover" that demonstrates how to 
implement automatic failover between different AI models when the primary 
model is unavailable or throttled. Include:
- A backend pool with priority-based routing
- Retry policy with exponential backoff
- Circuit breaker pattern for unhealthy backends
- Built-in LLM logging to track usage across all backends
- Test the model with a LangChain agent: https://docs.langchain.com/oss/python/langchain/agents
Use gpt-4.1-mini as primary and gpt-4.1-nano as fallback, deploy to Sweden Central.

Copilot will generate the complete lab structure including:

• 📓 Jupyter notebook with step-by-step instructions
• 🦾 Bicep infrastructure template
• ⚙️ APIM policy XML
• 📖 README documentation
• 🧹 Cleanup notebook

🏛️ Well-Architected Framework

Labs are designed following Azure Well-Architected Framework principles:

| Pillar | Labs | |--------|------| | Security | Access controlling, Content safety, Private connectivity | | Reliability | Backend pool load balancing, Token rate limiting | | Performance | Semantic caching, Model routing | | Operations | Built-in logging, Token metrics emitting | | Cost | FinOps framework, Semantic caching |

📕 Enterprise AI Gateway e-Book

Download the Enterprise AI Gateway e-Book for comprehensive end-to-end view of the Enterprise AI Gateway pattern, explaining why a centralized governance layer is essential for organizations adopting AI at scale and how it can be practically implemented using Azure API Management and Microsoft Foundry.
It describes the AI Gateway as a control plane that mediates all interactions between AI apps and agents and the underlying models, data, and tools, enabling consistent enforcement of security, safety, cost controls, resiliency, scalability, observability, and governance. Overall, the e-Book positions the Enterprise AI Gateway as a foundational architectural component that allows enterprises to innovate rapidly with AI while maintaining trust, compliance, visibility, and control.
