Dellenny presents a comprehensive, hands-on blueprint for creating agentic AI with Azure, guiding readers through architecture, implementation, and practical integration of AI services and serverless tools.

Designing and Creating Agentic AI in Azure

The AI landscape is evolving rapidly, and agentic AI—autonomous systems capable of planning and executing tasks—has become a major focus. Microsoft Azure offers a robust set of services for building these next-generation agents. This guide explores what agentic AI is and provides a step-by-step approach to architecting, implementing, and deploying such systems using Azure services.

🧠 What is Agentic AI?

Agentic AI systems operate with autonomy and can:

  • Understand and decompose goals
  • Plan and execute tasks
  • Invoke external services or APIs
  • Adapt to environmental changes
  • Learn from feedback

Unlike traditional AI that reacts to prompts, agentic AI takes initiative, orchestrates tools, and manages complex workflows.

🔧 Key Azure Tools for Agentic AI

Service Role
Azure OpenAI Natural language understanding (GPT models)
Azure Functions Serverless code execution
Azure Logic Apps Workflow orchestration
Azure Cognitive Search External knowledge/document retrieval
Azure Cosmos DB Agent memory/state storage
Azure Machine Learning Custom model training/evaluation
Azure AI Studio Prompt engineering and orchestration

🏗️ Architecture of Agentic AI on Azure

Sample Workflow:

  1. User Input → Azure OpenAI (GPT)
  2. Planning Module
    • Task breakdown (Chain-of-Thought, Tree-of-Thought)
  3. Tool Selection
    • Call Azure Functions/Logic Apps for execution
  4. Result Evaluation
    • Interpret results and decide next steps
  5. Final Output

Core Components:

  • Prompt Orchestrator: Define agent behavior in Azure AI Studio.
  • Memory Management: Use Cosmos DB or Blob Storage for conversation and state storage.
  • Tool Calling: Integrate Azure Functions for actionable steps—sending emails, querying databases, etc.
  • Reasoning Loop: Implement recursive execution using GPT’s function-calling API (ReAct, AutoGPT, BabyAGI patterns).

🛠️ Step-by-Step Guide: Building Agentic AI

  1. Set Up Azure OpenAI
    • Deploy GPT-4/GPT-4-turbo in Azure Portal
    • Enable function calling features
  2. Define Agent Prompts
    • Example: System prompt for a task-solving agent (via Azure AI Studio or prompt engineering tools).
    System Prompt: You are a task-solving agent. When a user provides a goal, break it into steps. Use tools as needed, reasoning step-by-step.
User: I want to organize a meeting with my team next week.
  3. Enable Function Calling
    • Define a JSON schema for tools the agent can use (e.g., schedule_meeting for Outlook integration).
    {
  "name": "schedule_meeting",
  "description": "Schedules a meeting using Outlook calendar",
  "parameters": {
    "type": "object",
    "properties": {
      "date": { "type": "string" },
      "time": { "type": "string" },
      "attendees": { "type": "array", "items": { "type": "string" } }
    },
    "required": ["date", "time", "attendees"]
  }
}
    • Bind schema to an Azure Function integrated with Microsoft Graph API.
  4. Create Function and Logic Apps
    • Use Azure Functions for custom logic (e.g., scheduling a meeting):
    # Example Azure Function to schedule a meeting
import requests
def main(req):
    data = req.get_json()
    # Call Microsoft Graph API to schedule a meeting
    return {
        "status": "success",
        "details": f"Meeting scheduled for {data['date']} at {data['time']}"
    }
  5. Implement Reasoning Loop
    • Let GPT model plan, execute tools, and update agent state, iterating as needed.
    • Orchestrate complex chains via Logic Apps or custom Python code.
  6. Add Long-Term Memory
    • Use Cosmos DB to persist goals, actions, and context.
    • Enable retrieval with semantic search if needed.

🤖 Example: Enterprise Assistant

Build a corporate assistant capable of:

  • Answering internal company questions
  • Scheduling meetings
  • Summarizing emails
  • Generating reports

Architecture Overview:

  • Azure OpenAI (GPT-4-turbo)
  • Azure Cognitive Search (knowledge retrieval)
  • Azure Functions (execution)
  • Azure Logic App (workflow)
  • Cosmos DB (memory management)

🧩 Best Practices

  • Input Validation: Double-check function inputs before execution.
  • Feedback Loops: Prompt users for confirmation (“Did this work?”).
  • Observability: Use Azure Monitor for logs, tracing, and cost tracking.
  • Security: Implement RBAC and secure all APIs.
  • Prompt Evaluation: Utilize promptflow or Azure ML pipelines to continuously test prompts.

For hands-on implementation, follow each step to implement robust, autonomous agents leveraging the breadth of Microsoft Azure’s AI ecosystem.
