Most GenAI prototypes never reach production — they break on security, scale, and runaway cost. AWS AI Engineering Specialist Dennis Traub explains how European founders take AI from MVP to real deployment with the Model Context Protocol (MCP), agentic workflows, and Amazon Bedrock. It is a practical map of the 2025 production AI stack, from model serving and orchestration to evaluation, cost monitoring, and GDPR-grade isolation.

Why this episode matters: The gap between an AI demo and a production system is where most startup projects die — and where reliability, cost, and data-protection exposure are actually decided. This is the playbook for crossing it without breaking at scale.
In this episode, we cover:
- The three things that break GenAI in production: security, scalability, and observability/cost
- Model Context Protocol (MCP) — the open standard for connecting AI agents to real APIs and data
- Non-agentic vs. agentic vs. multi-agent systems — and when NOT to build an agent
- The 2025 production AI stack: model serving, orchestration (LangGraph, LlamaIndex, CrewAI, Strands Agents), evaluation and cost monitoring
- AWS building blocks: Amazon Bedrock, Guardrails, Knowledge Bases, S3 Vectors, and Bedrock AgentCore
- Why GDPR-grade service isolation matters the moment you connect AI to customer data
