AI BriefingSingle LLM Gateway Architecture: Managing Claude Code and Codex in One Place via Amazon Bedrock
Key point
A single LLM Gateway architecture makes it possible to unify cost, security, and observability management across various AI coding agents.
Details
In enterprise environments, when adopting AI coding agents such as Claude Code and Codex, ensuring developers' freedom to choose their tools while maintaining consistent organization-wide governance has emerged as a key challenge.
Organizations need to secure control across five areas: usability, budget, MCP (Model Context Protocol), security, and Observability. If each tool implements these features individually, management complexity increases exponentially, which is why a Single Entry Point—an LLM Gateway—through which all requests pass is needed.
In particular, within Amazon Bedrock, Bedrock-Runtime (the Claude family) and Bedrock-Mantle (the latest GPT/Claude models) differ in API format, authentication method, and support for observability features. A single gateway absorbs these technical differences internally and provides developers with a unified interface.
This architecture presents a method for using the open-source LiteLLM to build a gateway on EC2 within a Private Subnet in the Seoul region, and storing logs and metrics in Amazon RDS for PostgreSQL to configure an integrated operating environment.
