Azure Workload Design: A Framework for Zone-Resilient Architectures
This article outlines a design framework for building zone-resilient Azure workloads, advocating a component-by-component analysis instead of a default "three zones everywhere" approach. It explains how to determine the optimal number of availability zones for each workload component to balance resilience, cost, and operational complexity. The guidance differentiates between service-managed zone-redundant and customer-managed zonal resources, helping architects and engineers make informed decisions. It emphasizes identifying requirements for resource availability, data consistency, and durability before optimizing for cost.

- Component-Level Design for Azure Zone Resiliency
This framework advises a component-by-component approach to designing zone-resilient Azure workloads, challenging the default assumption of three availability zones for all. It differentiates between Azure-managed zone-redundant and customer-managed zonal resources. The guidance helps architects and engineers evaluate requirements for individual components to optimize for resilience, cost, and operational complexity.
