Decision Guides

Each guide walks through service choices in one Azure domain. Selection criteria, SLA math, cost trade-offs, and the situation each service actually fits. Written from the angle of an architect defending a choice in a review.

Section 02

Working Tools

Interactive calculators and generators that produce values you can defend in a review. Composite SLA across dependencies, monthly cost projections against real Azure pricing, CAF-compliant resource names, WAF assessment scoring against the five pillars.

By the numbers

Built over a year of architecture reviews and landing zone work.
