Modernizing Mission-Critical Retail Applications with Azure - Strategies for Resilience and Scale

Explore practical strategies for modernizing mission-critical retail applications to Azure through this intermediate-level conference talk from Microsoft Ignite 2025. Learn from Sam's Club's real-world transformation journey as speakers Gautam Chandra and Justine Cocchi demonstrate technical approaches for migrating legacy monolithic applications to cloud-native microservices architecture. Discover foundational concepts of fault tolerance and high availability before diving into hands-on guidance for implementing key resilience patterns across Azure Kubernetes Service (AKS), Azure SQL, and Cosmos DB. Master scaling and resilience strategies including multi-region deployment, SDK tuning, and active-active system architecture through live demonstrations of failover simulations with zero service disruption. Examine simplified e-commerce architecture patterns using Azure services and understand the Saga pattern implementation for maintaining data consistency across distributed microservices. Gain insights into Azure SQL Hyperscale for scaling compute and storage while learning how to operationalize resilience patterns for improved performance and scale in production Azure environments.
