Azure Well Architected

3. Cost Optimization

Maximizes the value of every dollar spent on Azure.

• Optimization Mindset: Continuously monitor and refine resource usage.
• Right-sizing: Match resource capacity to demand; use Autoscale where applicable.
• Commitments: Leverage Azure Reservations and Savings Plans for predictable workloads.
• Cost Observability: Use Azure Cost Management and Tags for granular visibility.

4. Operational Excellence

Ensures smooth deployments and high observability.

• Infrastructure as Code (IaC): Use Bicep, Terraform, or ARM Templates for all deployments.
• Observability: Use Azure Monitor, Application Insights, and Log Analytics for health checks.
• Automation: Automate CI/CD pipelines with integrated policy gates.
• Software Quality: Implement comprehensive unit, integration, and performance testing.

5. Performance Efficiency

Scales workloads to meet user demand efficiently.

• Scaling: Favor Horizontal Scaling (Scale-out) over Vertical Scaling (Scale-up).
• Load Balancing: Use Azure Front Door, Application Gateway, or Traffic Manager.
• Performance Profiling: Regular load testing and bottleneck analysis.
• Data Patterns: Use Caching (Azure Cache for Redis) and CDN for static assets.

Specific Workload Guidance

• AI/LLM Workloads: Optimize GPU utilization, manage API rate limits (AOAI), and monitor prompt tokens for cost control.
• SaaS Solutions: Implement multi-tenant isolation, scalable data partitions, and metering/billing integration.
