He explains how to structure "stream-aligned" teams and use a "tiger team" for foundational architecture. He also discusses the sociotechnical benefits of reducing external dependencies and shares how to use guardrails and discovery services to achieve 25+ deployments per day.

Google Explores Scaling Principles for Multi-agent Coordination

Google Research tried to answer the question of how to design agent systems for optimal performance by running a controlled evaluation of 180 agent configurations. From this, the team derived what they call the "first quantitative scaling principles for AI agent systems", showing that multi-agent coordination does not reliably improve results and can even reduce performance.

Article: Architecting Agentic MLOps: A Layered Protocol Strategy with A2A and MCP

In this article, the authors outline protocols for building extensible multi-agent MLOps systems. The core architecture deliberately decouples orchestration from execution, allowing teams to incrementally add capabilities via discovery and evolve operations from static pipelines toward intelligent, adaptive coordination.
