AWS vpc documentation change
Summary
Restructured documentation by consolidating procedures, removing standalone sections about creating route tables and subnet associations, and updating terminology for clarity. Changed focus from 'changing' to 'managing' route tables.
Security assessment
The changes are organizational/editorial improvements rather than security fixes. While route table configuration impacts network security, there's no evidence of addressing specific vulnerabilities. The removed 'Associate or disassociate' section was procedural rather than security guidance.
