AWS elasticloadbalancing documentation change
Summary
Revised prerequisites for enabling zonal shift, specifying target group requirements (protocols, ALB exclusion, connection termination settings, and cross-zone attributes).
Security assessment
Operational documentation update clarifying feature requirements. Changes relate to availability/redundancy configuration rather than security controls.
