KubeCon + CloudNativeCon Europe 2025

This poster session showcases Chorus, an open-source tool that simplifies migrating and backing up object storage, like S3 or Swift. It begins with a quick overview of Chorus's features, followed by a live demonstration of its capabilities in action.

Attendees will explore two key migration strategies and their impact on disaster recovery goals—Recovery Time Objective (RTO) and Recovery Point Objective (RPO):

1. Zero-downtime migration: Avoids downtime (zero RTO) during normal operations but risks non-zero RPO if updates are lost during unexpected issues.
2. Zero-RPO migration: Ensures no data loss (zero RPO), even during failures, but requires planned downtime, resulting in non-zero RTO.

The session provides practical insights, trade-offs, and best practices for large-scale S3 migrations. It also empowers users to move beyond vendor-locked solutions with guidance on adopting cloud-native object storage tools like Rook.
