"Which framework should I use?" I've been asked this question more than any other in the past year. And the honest answer has always been: it depends on your architecture. That's why I saved it for the finale. Part 5 of my Agentic AI Architectures series is live: Shipping It — Frameworks, Production & the Architecture Decision Guide. This is the episode where theory meets reality. 1. The framework breakdown. Nine frameworks. No fluff. Here's the honest mapping: → LangGraph — Maximum flexibility. DAGs and state machines in Python. The Swiss Army knife. Pick this when you need full control and don't mind writing more code. → CrewAI — Fastest path to orchestrator-worker systems. Define agents as roles, give them tools, ship. Great for prototyping. Outgrow it for complex production. → AutoGen (Microsoft) — Best abstractions for agents that talk to each other. Debate, refine, collaborate. If your agents are peers, not workers, start here. → Amazon Bedrock Agents — Native AWS integration for single-agent tool use. Lambda, S3, DynamoDB out of the box. Path of least resistance for AWS shops. → AWS Step Functions + Bedrock — Production-grade DAG pipelines. Built-in retries, error handling, CloudWatch. The gold standard for enterprise workflows on AWS. → Claude Code — Code-Act in a terminal. Reads files, writes code, runs tests, iterates. Unmatched for code migration and refactoring. → OpenAI Swarm — Minimal. Agents are functions. Handoffs are first-class. Perfect for routing. → Semantic Kernel — Enterprise-friendly for .NET teams. → DSPy — Programmatic prompt optimization. Research-grade. High ceiling, steep learning curve. For most enterprise teams on AWS? Bedrock Agents for simple workflows + Step Functions + Bedrock for complex pipelines. That's the combination. 2. The 5 production concerns nobody talks about until something breaks: Observability — If you can't trace a request through every agent and every tool call, you can't debug it. Period. Cost control — Model tiering + caching + token budgets + early exit = 73% cost reduction in our implementations. Error handling — Design for failure from day one. Retries, fallbacks, dead-letter queues, human escalation. Guardrails — Validate at every agent boundary. Not just the edges. Agent-to-agent communication needs validation too. Latency — Parallelize. Stream. Go async. A 5-agent workflow doesn't have to feel like 5 sequential waits. 3. The decision guide. Which architecture for which use case: Code migration (Hive→PySpark, Databricks→EMR) → Plan-and-Execute + Reflexion + Critic Migration assessment → Orchestrator-Worker + DAG Pipeline Interactive assistant → Single Agent (ReAct) + Human-in-the-Loop Automated workflows → DAG Pipeline + LLM Nodes Cost analysis → Single Agent + Structured Output Complex research → Multi-Agent Debate / Swarm And the most important takeaway from this entire series: Most production systems are hybrids. An orchestrator-worker where each worker runs a ReAct loop with reflection. A DAG pipeline where one node triggers a multi-agent debate. Don't get locked into a single pattern. Compose them. Three rules I'm taking forward: Pick deliberately — Match architecture to problem complexity Start simple — Single agent first, add complexity only when needed Evolve — Refactor your architecture as requirements grow That's the complete series. 5 episodes. 15+ architecture patterns. 9 frameworks. 6 use-case mappings. 5 production concerns. If you missed any part: Part 1 → Single-Agent Architectures (ReAct, Code-Act, Tool-Use Loop) Part 2 → Multi-Agent Architectures (Orchestrator-Worker, Hierarchical, Debate, Swarm) Part 3 → Workflow-Based Architectures (DAGs, State Machines, Plan-and-Execute) Part 4 → Reflection, Human-in-the-Loop & Agentic RAG Thank you to everyone who followed this series, commented, shared, and challenged my thinking along the way. Building in public makes the work better. Final question: What architecture pattern are you implementing first? I want to hear your plan. #agenticai #aiarchitecture #cloudmigration #dataengineering #genai #aws #langgraph #bedrock #llms #aiagents #enterpriseai
