# Architecture Overview

This document describes the high-level architecture of our platform.

## Core Components

The system is composed of several key services:

- **API Gateway** — routes external traffic
- **Auth Service** — handles user authentication
- **Data Pipeline** — processes incoming events

For more details see [the design doc](https://wiki.example.com/design).

### API Gateway

The gateway is built on [Envoy](https://envoyproxy.io) and handles
TLS termination, rate limiting, and request routing.

```yaml
listeners:
  - address: 0.0.0.0
    port: 8443
    tls: true
```

### Auth Service

Token-based authentication using JWT.  See [RFC 7519](https://tools.ietf.org/html/rfc7519).

```python
def verify_token(token: str) -> Claims:
    return jwt.decode(token, key=SECRET)
```

## Deployment

The platform runs on Kubernetes with Helm charts managed in the
`infra/` directory.  Refer to [ops runbook](./runbook.md) for details.
