Agentic AI System – Reference Architecture¶
Goal-driven • Multi-agent • Orchestrated • Observable • Reliable
1. User / Client Layer¶
- Web / Mobile App
- Chat / Voice
- API / SDK
- Enterprise Systems
2. Orchestration / Control Plane¶
- Orchestrator / Workflow Engine (Planner, Router, Scheduler, Policy Enforcer)
- Task Decomposition
- Agent Selection
- Plan & Execution Manager
- State & Context Manager
- Guardrails & Policy
3. Agent Layer (Specialized Agents)¶
- Research Agent — Search, analyze information
- Reasoning Agent — Reason, plan, make decisions
- Action Agent — Execute actions, call tools
- Data Agent — Query data, process info
- Communication Agent — Summarize, communicate
- ... (extensible)
4. Tools & Integrations Layer¶
- Web Search
- APIs
- Code Execution
- Databases
- File / Doc Processing
- Other Services
5. Memory & Knowledge Layer¶
- Short-term Memory (Context)
- Long-term Memory (Vector DB)
- Knowledge Base (Docs)
- Episodic / Event Store (History)
- User / Org Profile Store
6. Monitoring & Observability¶
- Tracing & Logging (End-to-end traces)
- Metrics & Dashboards (Latency, tokens, cost)
- Alerts & Notifications (Anomalies, failures)
- Audit & Compliance (Logs, audit trails)
7. Reliability & Failure Management¶
- Error Detection
- Retry & Backoff
- Fallback / Alternate Agents
- Human-in-the-loop
- Circuit Breaker
8. Governance & Security¶
- Authentication & Authorization
- Data Privacy & PII Protection
- Policy Enforcement
- Model & Prompt Guardrails
- Compliance & Audit
9. Foundation / Infrastructure Layer (Cross-Cutting)¶
- LLM Providers (OpenAI, Anthropic, Azure OpenAI, etc.)
- Model Gateway (Routing, Rate limits, Cost management)
- Vector DB (Pinecone, Weaviate, FAISS, etc.)
- Data Storage (Blob / Object / SQL)
- Queue / Event Bus (Redis, Kafka, SQS, etc.)
- Cache (Redis, Memcached)
- Secrets Manager (API keys, tokens)
- CI/CD & Deployment (Containers, K8s, Serverless)
Flow Legend¶
- User request enters the system
- Orchestrator decomposes task & selects agents
- Agents use tools & memory to execute
- Failures handled & state updated
- Observability captures everything; insights feed back
