This workshop explores building agent2agent (A2A) communication protocol which focuses on a practical use case: a purchasing concierge agent that handles user orders. You'll build and deploy the core business logic—a pizza and burger seller agent—as an A2A server on Cloud Run, leveraging frameworks like CrewAI and LangGraph.

Then, you'll create the user-facing A2A client, a purchasing concierge agent, utilizing ADK which deployed on Agent Engine. This agent will interact directly with users, then communicate with the seller agents you built to fulfill the order. This setup demonstrates a complete, end-to-end A2A workflow, where a client agent intelligently delegates tasks to a server agent to complete a request.
