Implementación well-architected framework en entornos multi-suscripción

Abstract

This paper presents the implementation of the Microsoft Azure Well-Architected Framework (WAF) in a corporate tenant managing more than five active Azure subscriptions, each with distinct workloads, responsible teams, and compliance requirements. The central problem identified is the inefficient and disorganized management of the multi-subscription environment, caused by the absence of a governance model, lack of network segmentation, non-standardized resource provisioning, and limited knowledge of cloud architecture best practices among subscription administrators. Based on the five pillars of the WAF — Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization — this work proposes a structured approach to diagnose existing gaps, design governance guidelines, standardize policies using tools such as Azure Policy, Management Groups, and RBAC, and define a target architecture that ensures environment segmentation, resource naming standards, and homogeneous environments. The expected outcome is a scalable and secure cloud governance model that aligns technical decisions with the organization's strategic objectives, reduces operational and financial risks, and fosters a culture of responsible architecture.
