Always On at Nexo: Assuring Resilience and Scale with CockroachDB

Nexo, a digital assets wealth platform, faced challenges with its legacy database as the market matured and client expectations escalated. The company's engineering team decided to migrate to CockroachDB, a distributed SQL database designed for global scale and unmatched resilience. Nexo required high availability, horizontal scalability, zero downtime during server updates, and support for native sharding capabilities. After implementing CockroachDB, Nexo successfully migrated all users in three months with zero downtime or user impact, achieving significant new efficiencies and reduced hardware capacity while maintaining consistent write latency and stability. The company's database modernization has enabled them to accelerate plans for digital asset leadership with complete confidence.
