Open Protocols for Agent Interoperability Part 4: Inter-Agent Communication on A2A

This article discusses the Agent-to-Agent (A2A) protocol, an open standard for inter-agent communication developed by the Linux Foundation. Key highlights include:

• Enables AI agents from different frameworks to communicate and collaborate effectively
• Supports secure agent discovery through Agent Cards
• Provides structured task execution and multiple transport options
• Offers robust security with authentication and authorization mechanisms
• AWS is supporting A2A through the Strands Agents SDK

The article provides a practical example of inter-agent communication using an HR and Employee Info agent, demonstrating how A2A enables seamless interaction between different AI agents across organizational boundaries.
