Validation Environment & Methodology

What was GDCR v4.0?

A vendor-agnostic architecture that routes API traffic by business domain (Sales, Finance, Logistics) instead of creating separate proxies for each backend system.

Key improvements (now obsolete):

• Binary search O(log n) for 20× faster lookups
• Zero-allocation string operations
• Case-insensitive routing
• Gateway latency: 15–26ms (40% faster than v14.2)

Validation results (SAP BTP sandbox):

• 33,000+ API calls tested
• 90% reduction in API proxies (41→4)
• 90% reduction in integration packages (39→4)
• 69% reduction in technical users (39→12)
• 95% faster deployments (273 min→14.5 min)
