Agents at Scale: Multi-Agent Architecture with A2A Protocol on Agent Runtime and ADK Integration

As AI agents take on more responsibilities, a single agent doing everything becomes hard to maintain, scale, and evolve. Different capabilities often need different deployment strategies, update cycles, or even different teams owning them.

• The A2A (Agent2Agent) Protocol solves the communication side — standardizing how agents discover each other’s capabilities and collaborate across frameworks and organizations.
• Gemini Enterprise Agent Platform Runtime solves the deployment side — a fully managed, serverless platform that hosts your agents with built-in A2A support, auto-scaling, secure endpoints, persistent sessions, and zero infrastructure management.

Together, they let you build specialized agents, deploy them as discoverable A2A services, and compose them into multi-agent systems.
