Multi-Intelligence Collaborative Networks Built on Open Protocols
The differentiating value of A2A lies in its open ecosystem led by Google and built by more than 50 vendors. Unlike single-vendor closed solutions, the protocol enables the interconnection of intelligences across technology stacks and business domains through fully open-source technical specifications (hosted on GitHub) and standardized interface design.
The ecosystem building consists of three strategic tiers: the base protocol tier defines core communication standards; the reference implementation tier provides Python/JavaScript implementation examples; and the application integration tier implants protocols into solutions across industries through partners such as Salesforce and SAP. For example, ServiceNow has integrated A2A into its ITSM products, enabling customers' existing workflow intelligences to interact directly with NLP intelligences developed by Cohere.
Comparative analysis shows that this open model has significant advantages over proprietary protocols: implementation costs are reduced by 601 TP3T, vendor lock-in risk is reduced by 751 TP3T, and standards evolution is three times faster (through GitHub community collaboration). Google has also set up a technical steering committee to ensure that the protocol is developed with stability and innovation in mind.
