# Building a Multi-Agent A2A Architecture on Snowflake and Microsoft Fabric — Without Replacing Either

Short summary

HealthIQ demonstrates a production-grade multi-agent A2A architecture that unifies healthcare analytics across Snowflake, Microsoft Fabric, and Azure OpenAI without replacing existing systems. Specialist agents own domain-specific data and tools, while a master orchestrator coordinates cross-domain queries and triggers actions. This separation—specialists focused on one domain, orchestrator focused on routing and synthesis—is how enterprise AI scales by adding specialists as the data estate grows.

• •Multi-agent A2A orchestration unifies Snowflake, Fabric, and Azure OpenAI without system replacement
• •Specialist agents own domains; master orchestrator coordinates queries and synthesizes cross-domain answers
• •Enterprise-scale pattern: add specialists per data domain without rearchitecting the orchestration layer
