Distilled architecture & design principles for building self-service developer platforms, control-plane / data-plane separation, and edge-centralized cross-cutting concerns — drawn from a senior platform engineer's 8-year retrospective on building Atlassian's Envoy-based load-balancing platform (Open Service Broker + Sovereign xDS control plane + AWS infra + sidecar model). Covers the three IaC layers (image / infra / runtime), the template+context pattern for dynamic proxy configuration…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Architecture & Design Principles — Platform Engineering at Scale A field-tested distillation of how to build a developer platform that serves ~1000 services across ~13 regions on ~2000 long-lived proxies, derived from an 8-year platform-engineering retrospective (Atlassian, 2017-2025). The talk is structured as a chronological build-up; this skill re-organises it as a **principle map** plus deep-dive references. ## Why this skill exists Platform-engineering content online tends toward two failure modes: 1. **Vendor demos** that show the happy path of a tool without the failure modes that emerged at year three. 2. **Conference talks** that describe a finished system without the sequence of decisions that produced it. This talk is unusual because it walks chronologically through *how* a small team built a self-service load-balancing platform, *which choices compounded*, and *which non-technical skills mattered most over eight years*. The principles below are the durable shape of that experience. ## Principle Map (with canonical grounding) Each principle is anchored to its canonical name in the established …

How to install
mdr add broomva/skills/architecture-design-principles@sha256:d88caec384d45a1eThe line at the top of this page pins the label git:20260628.307420c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
