Application Load Balancer enables configuring HTTP client keepalive duration

The article discusses a new feature in AWS Application Load Balancer (ALB) that allows configuring the HTTP client keepalive duration for communication between clients and the load balancer.

Specifically, the article covers:

• The HTTP client keepalive duration specifies the maximum time an ALB will maintain an HTTP connection with a client before closing it.
• This feature allows customers to gracefully terminate connections during deployments, migrations, or Availability Zone evacuations.
• The keepalive duration can be set between 60 seconds and 7 days, with a default of 3600 seconds (1 hour).
• The configuration can be done via the AWS Management Console, API, or CLI.
• There is no additional charge for using this feature.
• The feature is available in all commercial AWS Regions.
