ABN AMRO Clearing: Financial Systems on Postgres Plus
A Global Bank Left Vendor Lock-In Behind — and Never Looked Back. Skepticism is the default response from a prospect who’s never engaged with EDB before, and the fastest way past it is proof from an organization they recognize. This customer story details how ABN AMRO Clearing’s infrastructure architects, facing high costs and vendor lock-in, moved to open-source-based Postgres Plus Advanced Server from EDB — a relationship that expanded over the following years as more of the bank’s footprint migrated to Postgres. It covers the specific systems moved, including a global reporting portal handling clearing transaction data and regulatory reports, and a legacy 1990s-era transactional trade capture system modernized as part of a European datacenter consolidation. Because it’s a specific, named financial-services account with concrete systems and timelines rather than a generic success story, it gives a net-new prospect a credible, relatable proof point grounded in a regulated industry.
