The Rise of Agent-to-Agent Protocols
Google Cloud’s Agent2gent (A2A) interoperability protocol was created to solve a pressing enterprise AI challenge: enabling agents built on different platforms to communicate. By standardizing agent interoperability, A2A helps organizations maximize the full potential of agentic AI by enabling agents across platforms to complex complex tasks.
Today, the A2A protocol is managed by the Linux Foundation and governed as an open-source project where anyone can contribute. Adoption is accelerating. Major technology players like Cisco, IBM, and Wells Fargo have partnered together, signaling growing confidence in A2A’s role as the foundation for interoperable AI. The collaboration among competing standards and leaders highlights the growing understanding among technologists of the need to unite, ensuring customers and users benefit from one unified protocol and technology capability.
In the future, Surapaneni envisions an “internet of agents,” where interoperable systems don’t just exist inside a single company but collaborate across industries and even consumer contexts. He explained that the early focus has been intra-enterprise, where identity and trust are simpler because everything operates under one sign-on.
The next frontier is B2B integration, where supply chain, finance, and partner ecosystems must exchange information securely across company boundaries. Beyond that lies B2C and consumer-to-consumer scenarios, where the stakes for privacy and identity management grow even higher.
Achieving it will require strong foundations in trust, authentication, and security, but Surapaneni sees it not only as possible, but happening soon.
“We need to come together as technologists into one community in support of one A2A protocol so that customers can benefit.”
