Google, Microsoft, and AWS adopt A2A Protocol, standardizing AI agent communication

The Linux Foundation’s A2A (Agent-to-Agent) Protocol reached major adoption milestones on its first anniversary.

More than 150 organizations now support the protocol as a key open standard for AI interoperability.

Google, Microsoft, and AWS integrated A2A into their core AI platforms to enable collaborative applications.

The protocol is currently in production use across several industries to facilitate agent discovery and transactions.

This common language allows AI agents to communicate across different frameworks, preventing ecosystem fragmentation and vendor lock-in.
