Digital bank Nubank migrates to CockroachDB to keep pace with rapid growth and improve infrastructure resiliency For more information visit or contact us. Nubank migrated its credit card authorization service from in-memory storage to CockroachDB to achieve scalable, always-on infrastructure and more efficient operations. Overview Nubank, the leading financial technology company in Latin America, sought a scalable SQL database for several critical services. The fintech initially stored data on-prem using an in-memory data store, but as the business rapidly grew, it needed a transactional solution for some applications. Nubank's team chose CockroachDB due to its ultra-resilience, simple scalability, strong consistency, and easy maintenance. They set up on-prem CockroachDB deployments and migrated their credit card authorization application. As the company continues to expand into new markets, they may migrate some apps to Amazon Web Services (AWS) and create a hybrid CockroachDB deployment that spans on-prem servers and cloud regions. Challenge Nubank is a Brazilian digital bank. Founded in 2013, it quickly grew to become the largest independent digital bank in the world, with over 13 million customers. Nubank was built to address Brazil's excessively high borrowing rates and poor banking customer experience. The company offers fee-free credit cards, digital savings accounts, and personal loans, which are all accessible from mobile devices. We have a highly complex transaction environment where we are continually searching for simplicity, scalability, and robustness –Gabriel Melo, Engineering Manager at Nubank
