Reference architectures / landing zones

Why important?

Reference architectures accelerate secure standardization (networking, IAM, logging, guardrails). Without these patterns, implementation risk increases.

How measured?

• 0 = No reference architectures/landing zones
• 1 = Generic high-level guidance only
• 2 = Simple references, little depth/automation
• 3 = Usable landing zones/blueprints for core scope
• 4 = Comprehensive references (security, networking, IAM) + IaC templates
• 5 = Very comprehensive + validated (best practices) + broadly evidenced
• N/A = no reliable evidence
