Seamless Application Failover
Seamless application failover is essential, particularly when transitioning your private virtual IP across Availability Zones (AZs). A fundamental principle for constructing highly available applications on AWS is to employ a multi-Availability Zone architecture. In the rare event of an AZ failure, this setup ensures that applications can continue functioning by utilizing resources from alternative AZs. Customers adopt various strategies to route user traffic to different components of their applications across AZs, including load balancers and Elastic IPs. In this article, we present a method for the failover of a private IP address across AZs. For expert insights on this subject, this resource is highly recommended.
