Guidance for Implementing Floating IP Addresses with Failover Capabilities on AWS
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.
Benefits
Strengthen application reliability automatically
Implement health monitoring and automated failover without manual intervention. Use static IP addresses for use cases where alternative, managed approaches don't fit.
Maximize operational insights
Gain visibility about the current and historical health of the application. Operate with confidence, based on data. Utilize systematic, automated processes to achieve high availability.
Optimize resource utilization costs
Eliminate idle infrastructure costs through event-driven architecture. Pay only for actual failover operations while maintaining continuous availability protection.
