Disrupting the Norm: Cloud-Based Data

Updating BUX’s data warehouse to comply with AFM standards demanded expertise. For one, BUX’s in-house legacy systems were not in line with its cloud-first standard of operating. Secondly, updating the near-obsolete infrastructure would be costly. The companyneeded a cloud-based option that would suit its needs for growth, scalability, and security. BUXfound Google’s core values of freedom and open-source aligned neatly with itsown goal of breaking down financial barriers. Google’s Cloud would provide BUX’s data platform. Xebia’s cloud experts were brought in to implement these changes so BUX could run more effectively and seamlessly. Xebia’s knowledge allowed BUX to hit the ground running.

Strategic Consolidation of IT Infrastructure

Building a solid cloud-based data infrastructure was what would give BUX the edge it needed in the highly competitive fintech market. BUX hired two of Xebia’s engineering specialists to accomplish this task. Xebia’s expert consultants overhauled BUX’s data architecture, bringing it to the cloud. The consultants started the process by brainstorming and then conducted an overall cost-benefit analysis of what BUX needed to succeed and scale. Their plan of action focused on finding a cloud server fitting BUX’s needs and then implementing this into BUX’s current architecture and workflow.

“For our new data stack, it was important to start with a solid basic infrastructure. Xebia helped us really well and advised us on setting everything up. Their specialist knowledge of Google Cloud has been extremely valuable to us.”
Derek Willemsen Head of Business Intelligence

Meeting Market Demands

BUX’s platform relies on real-time secured data, but with an outdated legacy system, it needed to transform its data architecture and take it to the cloud. Xebia provided the guidance and know-how to succeed. Transferring data from different sources required the development of a state-of-the-art network and then running applications through containers to ensure low-cost and high efficiency. The modular deployment of raw data through Airflow meant scalability allowing for lean data transfer, storage, and analysis. Three data pipeline clusters were created for testing and production. Knowledge becomes readily available so engineers can work to reach their targets and assess necessary changes. Data infrastructure improved as did performance and workflow with data stored in the cloud.
