Foundations of Well‑Architected Systems

2025-09-22 • Architecture

A short list of principles I apply on every system:

1. Clear SLOs and budgets before picking tools.
2. Observability baked in (structured logs, traces, metrics).
3. Blast radius is intentionally limited (isolate workloads).
4. Automate the boring stuff (CI/CD, deploy checks, runbooks).
5. Chaos and failure drills—fix design, not dashboards.
