Introduction of New AI Models and Enhanced Security

In AWS GovCloud (US), OpenAI’s open-weight GPT OSS models (120B, 20B) and NVIDIA Nemotron series (Nano 9B v2, Nano 12B v2, Nano 30B, Super 120B) are now available on Amazon Bedrock. These models are designed to enable government agencies to leverage the latest AI technologies while preventing the external leakage of confidential information.

Specific Implementation Steps:

  1. Access Amazon Bedrock in the AWS Management Console
  2. Search for gpt-oss-120b or nemotron-3-super-120b in the model selection screen
  3. Obtain the model’s API endpoint and integrate it into your application

Optimization of Agent Communication: Building a Serverless A2A Gateway

(Source: Building a serverless A2A gateway for agent discovery, routing, and access control)

Architecture Overview

The serverless A2A gateway consists of the following three layers:

  1. API Gateway: Centrally manages agent communication through REST API
  2. Lambda: Implements routing logic and access control
  3. DynamoDB: Stores agent registration information and permission management

Implementation Example:

# Building the gateway using Terraform (refer to official documentation)
terraform apply -var="gateway_domain=agents.example.com"

Practical Implementation Points

Three Actions Engineers Can Take Today

  • Enhanced Confidential Information Processing: Introduce Bedrock models running on AWS GovCloud (US) to completely restrict the external transmission of confidential data
  • Optimized Agent Communication: Use a Terraform-built A2A gateway to manage 190 connections with 20 agents using a single gateway
  • Automated API Documentation: Set up path-based routing for /agents/{agentId} in the API Gateway console to ensure compatibility with existing A2A clients
