Ensure that the AWS Auto Scaling Groups (ASGs) and their associated Elastic Load Balancers (ELBs) are sharing the same Availability Zones (AZs) in order to increase the performance of your auto scaling environments by allowing your applications to use AWS low-latency network links.
This rule can help you with the following compliance standards:
This rule can help you work with the AWS Well-Architected Framework
This rule resolution is part of the Cloud Conformity Security & Compliance tool for AWS
By using the same AWS Availability Zones for your Auto Scaling Groups and their load balancers (which run themselves on EC2 instances) you will get the lowest possible network latency.
To identify any unattached Elastic IPs currently available in your AWS account, perform the following: To determine if your ASGs share the AWS Availability Zones (AZs) with the ELBs attached, perform the following:
To configure your AWS Auto Scaling Groups to share the same availability zones with their load balancers, perform the following:
