Maturity models

This month, we introduced maturity models for the Azure Well-Architected Framework. Maturity models help you assess your current state and identify areas for improvement across the five pillars of the framework. Each model provides a structured approach to evaluate your workload's architecture and operations, enabling you to prioritize enhancements and track progress over time.

We reorganized the content to improve the information hierarchy, moving from a reference-style presentation to a guided learning approach that walks users through the methodology, principles, and design areas systematically. We also renamed the Illustrative examples section to Reference architecture examples and added video content.
  • Design principles of a mission-critical workload: We updated the Next step section. Both the link destination and link text changed from "Cross-cutting concerns" to "Architecture pattern" while keeping the same descriptive text about reviewing cross-cutting concerns for mission-critical workloads.
  • Grounding data design for AI workloads on Azure: We refreshed our guidance on grounding data by making it clear that data can come from various sources, such as databases with vector indexes and external systems, not only traditional indexes. The updates reflect the benefits of larger context windows in newer models, clarifies previous terminology around fine-tuning data, and highlights the importance of validating grounding data through real-world queries. Other improvements include updated guidance about security trimming, support for multi-media embeddings, and new considerations for agentic solutions.
