Summary

Restructured prescriptive guidance for network optimization, removed problem statement header, added generative AI inference optimizations and prompt engineering techniques

Security assessment

Changes emphasize network efficiency and sustainability (data transfer reduction, scalable services) without security references. Added AI optimizations focus on performance/token efficiency, not security. 'Risky configurations' refers to sustainability inefficiencies, not security vulnerabilities.

+Identify poor architectural choices and risky configurations as good candidates for remediation.

+Assess your workflows from the perspective of varying demand over time, so select scalable AWS services over fixed ones.

+Do not underestimate your network requirements, especially for peak loads. Provide sufficient failover resources to support your operations in case of partial outages.
