Challenge	The BNP Paribas IT team faced two major challenges. First, they needed to migrate customer data from a newly acquired bank into their central core banking system within a narrow time frame. This involved not only moving large volumes of data but also ensuring data integrity through a reconciliation process. The second challenge was to develop a new architecture to support their Internet banking initiative without disrupting the already reliable core banking systems. This required high performance and scalability to meet customer expectations for online banking services. Read More

Solution	The BNP Paribas IT team implemented Hazelcast to address their challenges. For the data migration project, Hazelcast was used as a fast operational data store in a cluster of 16 machines, each with 8 cores and 20 GB of RAM. This setup allowed them to perform the migration within the expected time window. For the Internet banking project, Hazelcast was used as a modern caching solution to provide data from core banking systems to frontend developers. This ensured high performance and minimal impact on core systems. Data synchronization was handled through Hazelcast, ensuring real-time data availability. Read More Log in to view content
