Ensure that your app-tier Auto Scaling Groups (ASGs) have associated Elastic Load Balancers (ELBs) in order to evenly distribute incoming traffic across all the EC2 instances available inside the ASG and help provide high availability for your applications. This conformity rule assumes that all AWS resources provisioned for your app tier are tagged with <app_tier_tag>:<app_tier_tag_value>, where <app_tier_tag> is the tag name and <app_tier_tag_value> is the tag value. Prior to running this rule by the Cloud Conformity engine, the app-tier tags must be configured in the rule settings, on your Cloud Conformity account dashboard.
This rule can help you with the following compliance standards:
This rule resolution is part of the Cloud Conformity Security & Compliance tool for AWS
Adding Elastic Load Balancers (ELBs) to your app-tier Auto Scaling Groups (ASGs) configuration can help you maintain the availability of the EC2 compute resources in the event of a failure and improve scaling for the instances behind these load balancers.
To determine if your app-tier ASGs have associated ELBs, perform the following actions:
To create an Amazon Elastic Load Balancer (ELB) and associate it with your app-tier Auto Scaling Group (ASG), perform the following actions:
