Case Study: ACI Worldwide achieves modernized software architecture, reduced risk, and lower costs with EnterpriseDB's EDB Postgres Distributed

ACI Worldwide Modernizes Software Architecture While Reducing Risk and Lowering Costs with PostgreSQL

ACI Worldwide, a global provider of mission‑critical real‑time payment software used by major banks and merchants, undertook a multi‑year modernization to reevaluate its database strategy. The team needed a responsive long‑term partner, a way to remove architectural compromises imposed by proprietary databases while supporting real‑time, active‑active multi‑data‑center replication, and a path to simplify and reduce licensing costs.

After a thorough evaluation ACI selected EDB Postgres Distributed for its native active‑active multi‑master replication and conflict resolution in a single, lower‑cost solution. The move delivered better performance and application flexibility, streamlined licensing and lower costs, a harmonized database architecture across ACI’s portfolio, and a collaborative long‑term partner—supporting ACI’s shift toward open source.
