AWS CodeDeploy now supports deploying to applications that use multiple AWS Elastic Load Balancers (ELB). Before, CodeDeploy could only support one application per Classic Load Balancers (CLB), Application Load Balancers (ALB) or Network Load Balancer (NLB). CodeDeploy now supports up to 10 load balancer target groups per application on Amazon Elastic Compute Cloud (EC2).
