Fiserv, a leading global fintech and payments company, prioritizes security, stability, and client satisfaction in its database selection process. The company's role is critical in the financial industry, with massive transaction volumes and strict regulatory requirements. Fiserv works with multiple vendors, including YugabyteDB, to select databases that meet its high standards for security, stability, and scalability. The company has a checklist of security requirements, including access levels, auditing, encryption at rest, and specific ciphers and protocols, which it mandates from vendors. Fiserv aims to achieve platform independence by building a private cloud based on Kubernetes and bringing YugabyteDB on-premises while applying the same protocols and requirements as the public cloud. The company's goal is to ensure consistency in operational models and databases, which is essential for scalability and efficiency, particularly in managing multiple clusters consistently.
