[Virtual] PRO Session (API): Scalable Region Failover for Microservices: Platform-Level Resilience at Intuit
Friday September 12, 2025 1:30pm - 1:55pm PDT
VIRTUAL API World -- Workshop Stage A (PRO)
Chaitanya Bhatt, Intuit, Principal Engineer
Akshay Pratinav, Intuit, Staff Software Engineer

In today’s distributed architecture, where APIs are the backbone of product experiences, regional outages can break critical customer flows and severely impact business continuity. At Intuit, we’ve built a Kubernetes-native platform that delivers seamless, scalable region failover for hundreds of microservices—enabling consistent API resiliency across the board.

This talk explores how our platform empowers services to declaratively onboard and define key components for failover—compute, databases, and routing. During a failover, the platform automatically pre-scales infrastructure in the secondary region based on live traffic data, promotes standby databases (Amazon Aurora, Redis, and others), and orchestrates traffic redirection via AWS Route 53 or Istio DNS controls. This eliminates manual guesswork, reduces recovery time, and helps ensure that API endpoints remain responsive and stable—even in disaster scenarios.

We’ll also compare the risks of non-standard, ad hoc failover strategies—which often result in brittle systems, untested assumptions, and high operational overhead—with the advantages of a standardized, platform-level approach. Our framework simplifies validation, reduces testing complexity, and enables teams to run game days and chaos experiments with greater confidence and less stress.

Attendees will walk away with practical techniques and patterns for building resilient APIs in a microservices-first world, and learn how investing in a failover platform creates a stronger foundation for disaster preparedness, operational excellence, and a better end-user experience.
