AWS Gateway Load Balancer supports sending TCP Reset packets when a target becomes unhealthy or is deregistered, reducing traffic interruptions from minutes to seconds
AWS Application Load Balancer and Network Load Balancer now support new TLS-based security policies compliant with RFC 9151 for CNSA 1.0 requirements, enabling compatibility with both CNSA and non-CNSA clients during transition.
Amazon CloudWatch Logs now supports Application Load Balancer logs as vended logs, improving observability and simplifying debugging for network traffic patterns.
