📌 What Is This?
These notes serve as a companion reference to the official Azure Well-Architected Framework documentation, focusing on the Cost Optimization pillar. They are designed for Cloud Solutions Architects involved in customer conversations around WAF reviews, cost governance, and financial optimization on Azure.
The content covers the full scope of Cost Optimization — from design principles and the official checklist, through practical savings mechanisms (Reservations, Savings Plans, Azure Hybrid Benefit), to the tools and governance practices that make cost discipline sustainable.
