Definition
The Agent2Agent (A2A) protocol is an interoperability standard that enables AI agents from different vendors to communicate and work together, similar to how API standards enabled application integration.
Purpose
A2A addresses the enterprise challenge of:
- Multi-vendor AI deployments
- Agent orchestration across platforms
- Cross-vendor communication without lock-in
Implementation Examples
IBM + SAP Partnership
IBM’s watsonx agents can now manage SAP’s Joule agents through A2A:
- Cross-vendor agent management
- Legacy system integration via Process Studio
- Context sharing between agent platforms
Industry Adoption
A2A represents a push toward standardized agent communication protocols, potentially becoming the “API standard” for AI agents.
