Orchestrator Pattern Enables Scalable Agent Microservices
This post outlines using an orchestrator pattern to build distributed AI agent microservices, demonstrated with a Course Creator example using Google's Agent Development Kit (ADK), the Agent-to-Agent (A2A) protocol, Pydantic, and Cloud Run. It explains splitting responsibilities among researcher, judge, and orchestrator services, deployment scaling benefits, and security caveats like mTLS and authentication. The approach lets frontends call a single endpoint while independent services scale and enforce structured JSON outputs.
Key Points
- 1Introduce orchestrator pattern using ADK and A2A to split agents into distributed microservices.
- 2Enable independent scaling and reduced latency by isolating researcher, judge, and orchestrator responsibilities.
- 3Allow frontends to call single orchestrator endpoint while services scale and enforce structured JSON contracts.
Scoring Rationale
Practical, actionable orchestration guidance boosts usability; limited originality and single-source tutorial reduce broader novelty and impact.
