- Azure Developer CLI (azd): A command-line tool that codifies best-practice deployment patterns, scaffolds infrastructure-as-code, and automates the full deploy lifecycle.
Scenario: Building an AI Chatbot with Azure OpenAI
To make the concepts in this guide concrete, we will follow a single, end-to-end scenario throughout: building and deploying an intelligent chatbot capable of answering user queries grounded in specific organisational data. This is one of the most common and high-value AI use cases in enterprise today.
The Goal
Create an intelligent, conversational chatbot that goes beyond generic responses by answering questions grounded in your own data — such as internal knowledge bases, product documentation, or customer records — using natural language.
Core Azure Services
Azure OpenAI powers the large language model (LLM) that understands and generates natural language. Azure AI Search retrieves relevant context from your data. Azure App Service hosts the web application that exposes the chatbot to end users.
Architecture Principles
The solution follows a Retrieval Augmented Generation (RAG) pattern, combining the generative power of an LLM with the precision of vector search. Authentication uses managed identities, eliminating the need for any stored secrets or passwords.
Advanced Scenarios and Tools
Once you are comfortable with the core chatbot pattern, Azure's AI platform opens the door to a wide range of advanced scenarios. These capabilities allow you to process complex document types, expose your application's intelligence to external consumers, and integrate seamlessly with the emerging ecosystem of AI coding assistants and agent frameworks.
Custom Document Processing
Azure AI Document Intelligence (formerly Form Recogniser) enables you to extract structured data from virtually any document format — PDFs, images, Word documents, and more. It offers both pre-built models (for invoices, receipts, identity documents, and tax forms) and fully custom models trained on your own document types via Azure Machine Learning Studio's labelling interface.
A typical pipeline might ingest scanned contracts via Azure Blob Storage, trigger a Document Intelligence extraction via Azure Functions, store structured results in Azure Cosmos DB, and index them in Azure AI Search for downstream RAG retrieval — all fully automated and serverless.
OpenAPI Tools for AI Agents
Any API hosted on Azure App Service can be described using an OpenAPI 3.0 specification and registered as a callable tool for AI agents. This means your existing business logic — pricing engines, inventory systems, booking APIs — instantly becomes accessible to LLM-powered agents without rewriting a single line of backend code.
The agent uses the OpenAPI schema to understand what the tool does, what parameters it expects, and what it returns. The LLM then autonomously decides when and how to call it based on user intent.
Model Context Protocol (MCP)
The Model Context Protocol (MCP) is an emerging open standard that allows any application to expose its capabilities as a standardised server consumable by AI coding assistants such as GitHub Copilot, Claude, and others. By hosting your App Service application as an MCP server, your internal tools, APIs, and data sources become first-class context providers for AI-assisted development workflows — dramatically boosting developer productivity across your entire organisation.
Step 1: Setting Up Your Azure Environment
A well-configured development environment is the foundation of a successful Azure AI project. Before writing any application code, you must establish authenticated access to your Azure subscription and provision the necessary cloud resources. The Azure Developer CLI (azd) makes this process repeatable, scriptable, and aligned with best practices from day one.
Prerequisites
- An active Azure subscription with sufficient quota for Azure OpenAI models in your target region (e.g., East US, West Europe).
- Visual Studio Code installed with the Azure Tools extension pack and the Azure Developer CLI (azd) extension enabled.
- Python 3.9+ or Node.js (depending on your chosen language runtime) along with Git for source control.
- Appropriate RBAC permissions on your subscription: at minimum Contributor role, plus the ability to create role assignments for managed identity configuration.
Key Commands
Authenticate your local environment:
azd auth loginInitialise a new AI agent project scaffold:
azd ai agent initProvision all resources and deploy the application in a single step:
azd upThe azd up command orchestrates resource group creation, Bicep template deployment, role assignment, and application deployment — all idempotently. Running it again will only apply changes, making it safe for iterative development.
Building Production-Ready Agents with Microsoft Foundry
Bringing AI applications to production demands more than just building models; it requires a robust, secure, and scalable infrastructure.
Azure provides an end-to-end platform, from development with comprehensive SDKs and sample projects to deployment using Infrastructure as Code (Bicep) and continuous monitoring with Azure Monitor.
This guide has walked through setting up your environment, developing with secure integrations like managed identities, and deploying to production while adhering to the Microsoft Well-Architected Framework. Leveraging Azure AI Studio, alongside tools like azd, streamlines the journey from concept to enterprise-ready AI agents.
Step 2: Developing Your AI Application
With your environment configured and resources provisioned, you can begin building the application logic. Azure's developer experience is designed to be code-first: you work in familiar languages and frameworks, and Azure handles the orchestration, security, and scaling concerns beneath the surface.
Code-First Development with Sample Projects
Microsoft provides a rich library of reference implementations and solution accelerators on GitHub. For our chatbot scenario, you would clone a sample agent project — such as a Python hotel concierge agent — which provides a fully functional starting point including prompt templates, tool definitions, and RAG pipeline wiring. This accelerates development dramatically compared to building from scratch, whilst still allowing full customisation of business logic.
Secure Integration with Azure OpenAI
Connect your application to the Azure OpenAI endpoint using managed identities rather than API keys. Managed identities are Microsoft Entra ID principals automatically managed by Azure — they eliminate the need to store, rotate, or distribute secrets. Your application code simply calls the Azure SDK with DefaultAzureCredential, and Azure handles token acquisition transparently. This is the recommended, production-safe approach for all Azure service-to-service communication.
Azure App Service: Enterprise AI Hosting
Azure App Service provides far more than simple web hosting for AI workloads. It offers native integration with Foundry Tools via sidecar containers, allowing your application to access tool endpoints locally without network egress. It also supports local SLM (Small Language Model) hosting via the Phi SLM sidecar, enabling low-latency, cost-effective inference for lightweight tasks. Combined with VNet integration, private endpoints, and built-in authentication middleware, App Service delivers enterprise-grade security with minimal configuration overhead.
Architecting Enterprise Foundry for Claude
This article delves into how Microsoft Foundry simplifies the integration of advanced Large Language Models (LLMs) like Anthropic's Claude into complex enterprise environments. It explores Foundry's role in providing a robust, secure, and scalable framework that enables organisations to deploy production-ready AI applications.
Foundry streamlines the orchestration, security, and deployment aspects, ensuring that cutting-edge AI capabilities can be leveraged while adhering to enterprise-grade standards and best practices.
Step 3: Deploying to Production
Moving an AI application from a working prototype to a production-grade deployment requires careful attention to infrastructure reproducibility, security posture, and operational resilience. Azure's tooling and the Microsoft Well-Architected Framework provide a structured, opinionated path to get there.
Infrastructure as Code with Bicep
When you run azd ai agent init, the CLI automatically generates Bicep definitions for every resource in your solution — including Azure AI Foundry hubs, Azure AI Search instances, Azure OpenAI deployments, App Service plans, and all required role assignments.
Bicep is Microsoft's declarative infrastructure language that compiles to ARM templates. Benefits include:
- Version-controllable, reviewable infrastructure changes
- Idempotent deployments — safe to re-run at any time
- Module reuse across environments (dev, staging, production)
- Integrated what-if analysis before applying changes
Well-Architected Framework for AI
Microsoft's Well-Architected Framework (WAF) defines five pillars — Reliability, Security, Cost Optimisation, Operational Excellence, and Performance Efficiency — and provides specific guidance for AI workloads in each pillar.
- Security: Use private endpoints for all AI services, disable public network access, and enforce least-privilege RBAC.
- Reliability: Deploy across availability zones, configure autoscaling, and implement retry logic with exponential back-off for LLM calls.
- Operational Excellence: Integrate Azure Monitor, Application Insights, and OpenTelemetry from day one.
