ADR-017·Updated Oct 14 by Ada Lovelace

Enforce rate limiting at the API gateway

ProposedDeciders
ALMDKS
Oct 14, 2026

Context

Checkout API and Payments API each throttle requests in-process, with different limits. Bursts during the October sale exhausted the Payments pool while the gateway stayed idle.

Decision

All throttling moves to the API Gateway. Services stop implementing their own limiters; limits are declared per route in gateway/limits.yaml.

Consequences

One place to tune limits and observe rejections. The gateway becomes a hard dependency of every public route, so it runs with three replicas minimum.

Agreed. @Kenji Sato can we set the default to 600 req/min per client?

Before and after

The problems you know, solved one by one

Every one of these compounds over time. Here is what changes when the architecture lives in Archyl.

Today

Governance and compliance requirements

Regulated industries need auditable architecture documentation. Manual processes do not scale, and point-in-time snapshots become outdated immediately.

With Archyl

Conformance rules enforce standards

Define architecture conformance rules and automatically check compliance across all teams. Get conformance scores and detailed violation reports.

Today

No cross-team visibility

Dozens of teams build hundreds of services, but nobody has a complete picture. System boundaries overlap, dependencies are unclear, and impact analysis is guesswork.

With Archyl

DORA metrics track engineering performance

Measure deployment frequency, lead time, change failure rate, and recovery time alongside architecture health for a complete engineering picture.

Today

Legacy system documentation is missing

Critical legacy systems have no documentation. The engineers who built them have moved on, and reverse-engineering is expensive and error-prone.

With Archyl

Webhooks for enterprise integrations

Push architecture events to Slack, Teams, Discord, or any webhook endpoint. Integrate with your existing enterprise notification infrastructure.

Today

Teams use different tools and standards

Each team documents architecture differently -- Confluence, Draw.io, Miro, or not at all. There is no unified view of the organization's technology landscape.

With Archyl

9-language support for global teams

Full platform localization in English, French, Spanish, German, Chinese, Japanese, Portuguese, Korean, and Italian for internationally distributed organizations.
