Aurelien Gelbart's presentation at Cloud Field Day 23 highlighted a major European bank's successful deployment of a private cloud built on Scality RING and S3 APIs. The bank sought to consolidate disparate storage solutions, aiming for a lower cost per terabyte and easier adoption for its users. Leveraging Scality's offerings, the bank achieved these goals, fostering widespread adoption of the new platform and significantly reducing costs.

The bank's private cloud architecture comprises six independent RING clusters across three geographical regions, each with a production and disaster recovery platform. Utilizing Scality's native S3 API support, the bank implemented multi-site replication and object lifecycle policies to meet stringent financial compliance requirements. The implementation allows the bank to run hundreds of production-grade applications, including database backups, financial market data storage, and document management.

The success of this deployment is evident in substantial growth, with the platform scaling from one petabyte to 50 petabytes of usable storage within seven years. This growth brought new challenges related to performance and resource management across the many different applications. Scality addressed these challenges by improving software performance through reconfiguration and architectural improvements. The results are impressive: the bank now operates 100 petabytes of usable storage, manages 200,000 S3 buckets, and processes 300 billion client objects, achieving a 75% reduction in the cost per terabyte per year compared to its previous solutions.
