Experience Enhancements

Server Load Balancer (SLB) - ALB connection timeout increased to 3600 seconds

The maximum request timeout and connection idle timeout for ALB listeners has been increased from 900 to 3600 seconds. This enhancement provides greater stability for applications with long-lived connections, preventing timeout failures during operations like AI inference, large language model streaming, file transfers, and asynchronous processing.

Feature description: The maximum request timeout and connection idle timeout for Application Load Balancer (ALB) listeners has been significantly increased from 900 seconds (15 minutes) to 3600 seconds (1 hour). This enhancement is designed to support modern applications that require long-lived connections, preventing premature disconnections and request failures due to timeouts. This improves system stability, business continuity, and the end-user experience for a wide range of scenarios, including: long-running inference tasks, streaming responses from large language models (LLMs), waiting for AI training callbacks or other long-running async jobs, large file uploads and downloads, and real-time stream processing.
