Financial institutions often face challenges in utilizing their vast customer data due to siloed systems and costly mainframes, which can hinder customer service and operational efficiency. Elastic Cloud and Google Cloud offer a solution by enabling streamlined data management and advanced search capabilities, allowing institutions to access comprehensive customer profiles and transaction histories quickly. This integration supports improved customer experience, real-time customer insights through dashboards, partnership management with merchants, cost optimization, and enhanced risk reduction, including fraud detection. The architecture involves moving data from mainframes to Google Cloud, processing it in BigQuery, and utilizing Elastic Cloud for search functionalities. The use of serverless technologies like Dataflow facilitates efficient data processing, while advanced techniques such as remote ORC transcoding help minimize mainframe CPU consumption. This collaborative approach provides financial institutions with the tools to transform their data into strategic assets, enhancing service delivery and operational capabilities.
