Layered Agentic AI Architecture: Key Pillars and Implementation

Listen to this Post

Featured Image
A layered Agentic AI architecture is built on five key pillars, enabling autonomous, scalable, and secure AI operations. This framework enhances AI capabilities by integrating knowledge access, execution coordination, decision-making, continuous learning, and governance.

🔹 Knowledge & Access Layer

Connects AI agents to APIs, databases, and external tools for real-time data retrieval.

Commands & Tools:

  • Use `curl` to fetch API data:
    curl -X GET https://api.example.com/data -H "Authorization: Bearer TOKEN" 
    
  • Query databases via `sqlcmd` (SQL Server) or `psql` (PostgreSQL):
    SELECT  FROM datasets WHERE category='AI'; 
    
  • Scrape web data with wget:
    wget --mirror --convert-links https://ai-resources.org 
    

🔹 Execution & Coordination Layer

Breaks complex tasks into sub-tasks, manages workflows, and tracks progress.

Automation with Cron & Bash:

 Schedule a Python AI task 
0     /usr/bin/python3 /scripts/ai_agent_task.py >> /var/log/ai_tasks.log 

Multi-Agent Coordination with Docker:

docker-compose up -d ai_agent1 ai_agent2 

🔹 Decision & Cognition Layer

Hosts LLMs (e.g., GPT-4, Llama 3) and reasoning engines.

Run an LLM Locally:

ollama pull llama3 
ollama run llama3 "Explain Agentic AI architecture." 

Python Decision-Making Script:

from transformers import pipeline 
classifier = pipeline("text-classification") 
result = classifier("Should the AI agent fetch new data?") 
print(result) 

🔹 Learning & Feedback Layer

Uses reinforcement learning (RL) and A/B testing for self-improvement.

TensorFlow RL Training:

import tensorflow as tf 
agent = tf.agents.DQNAgent(...) 
agent.train(experience=dataset) 

Log Feedback with ELK Stack:

curl -X POST http://localhost:9200/ai_feedback/_doc -d '{"query":"error_rate", "response":"improved"}' 

🔹 Trust & Governance Layer

Ensures security, compliance, and auditability.

Linux Security Hardening:

sudo apt install auditd 
sudo auditctl -w /etc/passwd -p wa -k ai_access 

Windows Audit Logs:

Get-EventLog -LogName Security -Newest 50 | Where-Object {$_.EventID -eq 4624} 

You Should Know:

  • Multi-Agent Systems use Docker/Kubernetes for orchestration:
    kubectl create deployment ai-agent --image=ai/agent:v1 
    
  • API Security is critical—use JWT tokens:
    openssl genrsa -out ai_key.pem 2048 
    
  • Continuous Monitoring with Prometheus:
    scrape_configs: </li>
    <li>job_name: 'ai_agents' 
    static_configs: </li>
    <li>targets: ['ai-agent1:9090'] 
    

What Undercode Say:

Agentic AI transforms automation by enabling autonomous problem-solving. However, security risks (e.g., API breaches, model poisoning) require robust governance. Future systems will integrate quantum-resistant encryption (openssl genpkey -algorithm x25519) and federated learning (tensorflow_federated).

Prediction:

By 2026, 60% of enterprises will deploy multi-agent AI, leveraging architectures like Habib Shaikh’s framework.

Expected Output:

AI Agent Task Log: 
- [bash] Data fetched from API at 2025-06-07T14:30Z 
- [bash] Model retraining triggered via RL feedback 
- [bash] Security scan passed (CVE-2025-0000 mitigated)
