# Skyloom architecture overview

Basalt is our internal platform for circuit-breaker rollout. This page gives a high-level tour; per-component detail lives in the linked sub-pages.

## Components

- **auth-gateway** — the request-plane entry point; owns authentication and per-tenant routing
- **Storage layer** — sharded by tenant; hosted in ap-southeast-1
- **Event bus** — decouples billing-relay from downstream workers
- **Observability** — metrics, traces, and structured logs

## Data flow

Requests enter through ledger-api, are authenticated, and are either served synchronously from the read replicas or queued onto the event bus for asynchronous processing. Downstream workers consume from the bus with at-least-once semantics.

## Non-goals

This document is reviewed quarterly. If you notice anything out of date, edit the page directly and mention Kwame in the change log.

Ownership sits with the Halyard platform team. For questions, reach out to Elena or the team channel.
