## Introduction

Feel free to consume the documentation in any order you prefer, the quickstart is a good place to start to get going.

The Agent Gateway consists of 2 components:

* [Agent Registry](/product/agent-gateway/registry): A centralised registry of all agents in your organization with access control and observability.
* [Agent Servers](/product/agent-gateway/servers): Agent servers that act as a client to the upstream agent server and as a server to the downstream agent clients.

The agent gateway acts as a centralised proxy for your agent servers. Sitting in between your agent clients and your agent servers.

Here is a broad architecture diagram:
