AWS wellarchitected documentation change
Summary
Updated IoT sustainability best practices with revised numbering (IOTSUS02-BP01/BP02), added risk level assessments, and clarified guidance about Basic Ingest/QoS optimizations for energy efficiency
Security assessment
Changes focus on sustainability optimizations (energy efficiency via Basic Ingest and QoS selection) rather than security controls. While Basic Ingest mentions secure data transmission, this is existing functionality rather than new security documentation. The 'risk' references pertain to sustainability impact, not security risks.
