Answer 1

To create an Application Load Balancer using AWS CLI, you can use the following commands:

1. Create a load balancer:

   aws elbv2 create-load-balancer --name my-alb --subnets subnet-12345 subnet-67890 --security-groups sg-12345 

2. Create a target group:

   aws elbv2 create-target-group --name my-targets --protocol HTTP --port 80 --vpc-id vpc-12345 

3. Register targets (EC2 instances):

   aws elbv2 register-targets --target-group-arn arn:aws:elasticloadbalancing:region:account-id:targetgroup/my-targets/12345 --targets Id=i-12345 Id=i-67890 

4. Create a listener:

   aws elbv2 create-listener --load-balancer-arn arn:aws:elasticloadbalancing:region:account-id:loadbalancer/app/my-alb/12345 --protocol HTTP --port 80 --default-actions Type=forward,TargetGroupArn=arn:aws:elasticloadbalancing:region:account-id:targetgroup/my-targets/12345
