A2A Protocol Surpasses 150 Organizations, Lands in Major Cloud Platforms, and Sees Enterprise Production Use in First Year

On Thursday, the Linux Foundation announced the A2A Protocol marked its one-year anniversary with over 150 organizations supporting the open standard, including deep integration across Google, Microsoft, and AWS.
Adoption reflects a shift toward agent-based architectures, allowing disparate AI systems to collaborate without siloed, custom-built connections. Rao Surapaneni, Google Cloud Vice President, stated this momentum allows systems to work together across environments.
The core repository surpassed 22,000 GitHub stars, while the SDK ecosystem expanded to support five production-ready languages. Additionally, the Agent Payments Protocol enables secure transactions with more than 60 organizations supporting the initiative.
Microsoft integrated the protocol into Azure AI Foundry and Copilot Studio, while AWS added support via Amazon Bedrock AgentCore Runtime, embedding A2A directly into infrastructure to position it as a default standard.
Shifting from early adoption, A2A is becoming a core component of modern distributed system architecture as future development focuses on interoperability specifications, registry consolidation, and security best practices.
