Resource library
Resources exist to make the publication more practical. They should help readers review an architecture, validate an operating baseline, or identify where to drill deeper next.
Reading about architecture is useful. Having a checklist you can bring to your next design review is more useful. That's what resources are for.
Each resource below is a structured framework - not a blog post, not a tutorial. Something you print out, fill in for your specific system, and use to make a decision or validate a design. They're built from patterns that show up across the consulting work and the articles.
Some of these are available now as linked content. Others are being developed as standalone downloadable frameworks. If there's a specific checklist or worksheet you'd use in your architecture reviews, send a note to hello@rahulladumor.com - the resource library is built based on what engineers actually need, not what looks good on a landing page.
Available frameworks
Use it before a design review or migration decision to pressure-test assumptions around scale, blast radius, and operational fit.
Use this before any design review, migration decision, or system audit. It covers VPC design, IAM boundaries, data flow, failure modes, cost posture, and operational readiness.
Browse architecturesA working list for reliability, observability, cost, recovery, and security controls that should exist before traffic makes the decision for you.
Run through this before any production launch or major deploy. Covers reliability, observability, cost controls, recovery procedures, and security baseline.
Start hereMap your biggest spend drivers to the architectural decisions creating them, then decide what should actually be changed first.
Start here when your AWS bill is growing faster than your traffic. Maps spend to architecture decisions so you fix the cause, not just the symptoms.
Cost guidesA starting point for logs, metrics, traces, ownership, alert fatigue, and incident-debugging workflows that do not collapse under load.
Use this to evaluate whether your monitoring, logging, and alerting actually help during an incident - or just generate noise.
Reliability guidesDownload or bookmark the resource. Open it alongside your system's architecture diagram. Work through each section for your specific setup. The goal isn't to check every box - it's to find the gaps you didn't know existed.
Most teams find 3-5 things they'd missed. That's normal. The value isn't in perfection - it's in surfacing the risks before they surface themselves at 2am on a Saturday.
