Case Study: Nestle Purina Petcare achieves zero-downtime migration to microservices and doubles deployment velocity with LaunchDarkly

Nestle Purina Petcare - Customer Case Study

Nestlé Purina’s Petfinder and Hireology each faced risky, large‑scale migrations that threatened customer experience: Petfinder needed to break a legacy on‑prem monolith into microservices without disrupting the largest pet adoption site in North America, while Hireology needed to move a monolithic hiring platform to Azure while improving release reliability and speed.

Using LaunchDarkly feature flags and progressive rollout tactics, both teams migrated piece‑by‑piece, routed traffic between old and new systems, validated performance with targeted cohorts, and could instantly roll back if needed. Petfinder completed a zero‑downtime migration, doubled deployment frequency and improved DORA metrics; Hireology reduced change‑failure rate from 75% to 8%, increased deployments 14x, sped page loads by 65%, cut lead time from 14 days to 3 hours, shrank recovery to under an hour, and significantly lowered hosting costs.
