From bc9dc36c6c2c9550bc823ff1de13d55bc040ddfd Mon Sep 17 00:00:00 2001 From: Ben Duncan <5178243+benduncan@users.noreply.github.com> Date: Thu, 16 Jul 2026 12:09:22 -0500 Subject: [PATCH] Redesign architecture.svg in the Spinifex site theme MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rebuild the message-driven architecture diagram in the ember-on-ink theme to match platform.svg: ember gradient NATS bus, ember-tinted gateway and daemon cards, neutral clients and backend cards. Content unchanged (clients → gateway → NATS → ec2/ebs/s3/vpc/iam daemons → local backends).

- Spinifex message-driven architecture — AWS Gateway, NATS bus, service daemons + Spinifex message-driven architecture: standard AWS clients call the AWS Gateway over HTTPS with SigV4, which publishes to a NATS bus answered by stateless ec2/ebs/s3/vpc/iam daemons over local backends.

Every AWS API call is authenticated at the gateway, published to a NATS subject, and answered by whichever daemon claims it. Daemons are stateless — scale horizontally by starting more. No etcd, no Kubernetes, no external control plane. Deep dive: **[`docs/DESIGN.md`](docs/DESIGN.md)**.
