Case Study: Bouygues Telecom achieves consistent customer data and continuous network availability with DataStax Enterprise

Bouygues Telecom Optimizes the Quality and Availability of its Customer Data with DataStax

Bouygues Telecom, a major French telecommunications operator, needed to ensure that its provisioning APIs and customer-facing systems stayed available and delivered consistent customer data. Their legacy relational database risked complete data loss during site failures, so the team prioritized service continuity—even if it meant temporarily serving slightly stale data—while evaluating NoSQL options to meet strict availability and quality-of-service requirements.

They implemented DataStax Enterprise on Apache Cassandra with vendor support for migration and operations. The new distributed architecture delivers continuous availability across three sites, maintained service during node losses, improved handling of data consistency, and strong scalability and security; Bouygues expects to scale to about 1.5 billion transactions per day, boosting customer experience and satisfaction.
