Guidance for Implementing Floating IP Addresses with Failover Capabilities on AWS

Go to sample code

Overview

This Guidance demonstrates how to implement floating IP addresses in AWS Cloud environments, offering a robust high-availability approach when traditional methods like DNS updates or multi-Availability Zone (AZ) network load balancers aren't options. The approach maintains system accessibility through a single, static IP address while enabling seamless failover across AZs—crucial for organizations with strict compliance requirements or technical constraints. The Guidance significantly reduces application downtime and simplifies network management by eliminating the need to update multiple IP addresses across infrastructure during failover events.
