What problem does it solve? Choosing among Azure's overlapping services (Container Apps vs AKS vs Functions, Service Bus vs Event Hubs vs Event Grid, hub-spoke vs Virtual WAN) is error-prone, and wrong early decisions create costly re-architecture, outages, and surprise bills. ## Core Features & Use Cases - Decision Frameworks: Provides preference orders and comparison tables for compute, messaging, networking, storage redundancy, and databases, including crossover thresholds like the ~30-spoke hub-spoke to Virtual WAN tipping point. - Production Configuration Guidance: Covers AKS networking models, Cosmos DB partition-key design, Functions Flex Consumption, private endpoints, storage lifecycle tiers, and PTU vs pay-as-you-go for AI workloads. - Cost, Identity, and Retirements: Details Reservations/Savings Plans/Spot layering, managed identities and Zero Trust, Bicep vs Terraform, and 2024-2026 service retirements such as Azure AD B2C and the Log Analytics agent. - Use Case: When planning a new Azure landing zone or migrating workloads, ask which compute, messaging, and database services fit each workload and receive a staged production roadmap with concrete configuration defaults. ## Quick Start Ask the assistant to recommend Azure compute, messaging, and database services for a new multi-region SaaS application using this skill.
