Version 0.3 of the open-source Agent2Agent (A2A) protocol from Google introduces significant features such as gRPC support and security card signing. gRPC enables high-performance communication across distributed applications in various programming languages. This capability simplifies enterprise integration by allowing agents to work over a widely accepted language-agnostic protocol. Additionally, the new security feature ensures that agents can cryptographically prove their identity, essential for compliance and security in large organizations, particularly Fortune 500 companies.
gRPC's high performance and support for multiple programming languages make it suitable for complex, distributed applications, said Stephanie Walter, analyst at HyperFRAME Research.
For enterprises, gRPC support will allow agents to interoperate over a widely adopted, language-agnostic protocol. This simplifies integration with microservices and existing cloud-native architectures, Hinchcliffe said.
The ability to sign security cards is critical for developers and large enterprises, especially Fortune 500 companies, as they won't deploy agents that can't prove their identity cryptographically, said Paul Chada.
The new security capability will help enterprises ensure that appropriate access controls are in place, said HyperFRAME's Walter.
