# 4 security wins from Booking.com's hybrid cloud migration

**[HashiCorp](https://daily.dev/sources/hc)** · 6 min read · 2 upvotes · 0 comments

## Summary

Booking.com successfully scaled HashiCorp Vault to handle 500+ requests per second across 100+ Kubernetes clusters during their hybrid cloud migration. Their approach created a unified security bridge between multi-cloud environments, consolidated authentication complexity through JWT migration, implemented strategic cloud-native secrets management with Vault as single source of truth, and maintained cost-effective operations. The solution enabled self-service developer onboarding while maintaining security oversight across AWS, GCP, Alibaba Cloud, and bare metal infrastructure.
