How to use Health Checks to improve AWS Load Balancer Resiliency

The Elastic Load Balancer (ELB) in AWS is designed to provide high availability and fault tolerance, but its default setup can be limiting. By implementing custom health checks using multivalued DNS records, it's possible to improve the resiliency of ELBs by detecting issues more aggressively and taking corrective action sooner. This approach can help mitigate traffic loss and ensure higher levels of availability for applications running on AWS.
