AWS Trusted Advisor adds four new checks for Elastic Load Balancing

Posted on: Feb 26, 2015

AWS Support announces four new AWS Trusted Advisor checks that offer best practices for using Elastic Load Balancing (ELB), focusing on security and fault tolerance:

• ELB Connection Draining (Fault Tolerance category): Checks for load balancers that do not have connection draining enabled. Connection draining allows existing requests to be completed before the load balancer shifts traffic away from a deregistered or unhealthy back-end instance.
• ELB Cross-Zone Load Balancing (Fault Tolerance category): Checks for load balancers that do not have cross-zone load balancing enabled. Cross-zone load balancing makes it easier to deploy and manage applications across multiple Availability Zones.
• ELB Listener Security (Security category): Checks for load balancers with listeners that do not use recommended security configurations for encrypted communication.
• ELB Security Groups (Security category): Checks for load balancers that have misconfigured VPC security groups to help to make sure the load balancer works as expected and to reduce the risk of loss of data or malicious attacks.
