Load Balancing: An Auto Scaling group can be associated with an elastic load balancer. Select the elastic load balancer we created earlier in this chapter in the Creating Elastic Load Balancer section, a1electronicsecommerce-elb. If you are using other means of load balancing for your Auto Scaling group then uncheck this option.

Health Check Type: The Auto Scaling group performs health checks on the instances in the group and replaces the failed instances with new ones. It can either use the results of the elastic load balancer or monitor the state of the EC2 instance to detect a failed instance. Select the ELB option since we have configured our auto scaling group to use an ELB.

Health Check Grace Period: When an instance comes up it might take some time before it starts responding to the health checks. The time should always be greater than the expected boot time of the instance plus the startup time of the application. Choose the default value of 300 seconds. Now, click on the Next: Configure scaling policies button:
