Dellenny explains the core concepts of agentic AI and provides Azure-centric guidance for building autonomous, adaptive agents using Microsoft’s AI ecosystem.

How Agentic AI Works and How to Build It in Azure

What is Agentic AI?

Agentic AI refers to systems that go beyond static automation or Q&A, operating as autonomous, goal-oriented agents that can plan, act, and adapt with minimal human oversight. These systems bring together reasoning, planning, and learning to break down complex objectives, execute multi-step tasks, and improve over time.

The Agentic AI Feedback Cycle

  • Perceive: Gather information from APIs, datasets, or sensors and process it for context.
  • Reason / Plan: Break down goals, decide action order, and select required tools or data.
  • Act: Carry out API calls, data writes, system interactions, or communications as steps in a workflow.
  • Learn / Adapt: Assess outcomes, refine plans, and improve performance in future cycles.

This cycle enables dynamic, context-aware, and continuously adapting behavior.

Core Components

  • Large Language Models (e.g., GPT-4 via Azure OpenAI Service): Provide cognitive abilities, understanding goals, and generating actions.
  • Memory (e.g., Azure Cosmos DB/Table Storage): Store both recent and historical context and decisions.
  • API/Tool Integrations: Allow the agent to interact with businesses’ existing systems via Azure Logic Apps, Power Automate, or direct API calls.
  • Planning/Decision Modules: Enable prioritization and uncertainty handling.
  • Safety/Guardrails: Define operational boundaries and permission controls (RBAC, Azure Policy).
  • Observability: Monitor and audit agent actions (Azure Monitor, App Insights).

Why Agentic AI?

Agentic AI is optimal for automating entire workflows that involve reasoning, such as:

  • Virtual support and IT agents
  • Dynamic workflow or business process automation
  • Automated reporting and data analysis agents
  • Personalized assistants for enterprise
  • Proactive monitoring and compliance tasks

Such AI reduces routine effort, adapts to changing input, and improves via feedback.

Key Challenges

  • Data Quality: The agent’s reasoning depends on trustworthy data.
  • Oversight/Trust: Agents must explain decisions for human review.
  • Architectural Complexity: Multiple interacting components must be designed and maintained.
  • Security and Privacy: Sensitive data and actions require robust controls.
  • Cost Management: Large models and integrations may incur significant compute costs.

Step-by-Step: Building Agentic AI on Azure

  1. Define Use Case and Scope: Identify business process, goals, inputs/outputs, constraints, and criteria for success.
  2. Select Language Model: Use Azure OpenAI Service for GPT-4-turbo or similar; apply prompt engineering or fine-tuning for domain needs.
  3. Agent Execution Framework: Leverage Azure Functions or Azure Container Apps to host agent logic; use Logic Apps for workflow orchestration and API connectivity.
  4. API and Tool Integration: Use Logic Apps and connectors to give the agent access to required external/internal systems.
  5. Memory and Context: Store conversation or state in Cosmos DB; use Azure Cognitive Search or Vector Search for semantic retrieval.
  6. Build Guardrails: Use Azure AI Content Safety, RBAC, and Policies to manage access and filter unsafe actions.
  7. Monitoring: Implement Azure Monitor and Application Insights for auditing and performance tracking.
  8. Iterate/Improve: Capture telemetry; improve models and logic via Azure Machine Learning and feedback loops.

Example Architecture

  1. User Input: Entered via web app or Azure Bot Service.
  2. Cognitive Layer: Azure OpenAI Service interprets with LLM.
  3. Action Layer: Azure Functions/Apps execute tasks.
  4. Memory: Cosmos DB & Cognitive Search for data and history.
  5. Feedback: Observed via Azure Monitor; used for retraining/adaptation.

What’s Next?

Future agentic AI will feature multi-agent ecosystems collaborating on complex goals. Azure’s scalable, secure cloud infrastructure provides the needed platform for such architectures to grow.

For detailed implementation, the author suggests adding reference architecture diagrams or a step-by-step deployment guide with Azure OpenAI and Semantic Kernel integration.
