Guides walk through an implementation end-to-end. Architecture, code, deployment, trade-offs, failure modes, and cost. The longest format - typically 2000+ words.
Patterns describe a reusable system shape. When to use it, when not to, what breaks, what it costs. Shorter than guides, more focused on the decision.
Postmortems break down what went wrong, why it went wrong, and what changed afterward. Real incidents, real blast radius, real recovery.
Cost analyses dissect where AWS spend comes from and which architectural decisions drive it. Real numbers, not hand-waving.
Premium deep dives go further. Full deployable CDK stacks, decision matrices, annotated code, and edge case analysis. Free members can access everything.
