T-Mobile DataStax Distributed Data Systems Operational Support

T-Mobile US, Inc. (NASDAQ: TMUS) is an American wireless network operator with one of America's largest and fastest telecom and 5G network that has revolutionized the telecom and internet sectors through continuous innovation and by launching new products and services.

T-Mobile uses DataStax Enterprise Cassandra as a high-performance, horizontally-scalable real-time data store behind some of their most critical customer-facing systems.

DataStax brought RhinoSource into T-Mobile to assist with operational support for their DataStax Enterprise Cassandra clusters and to assist with security and backup & recovery setup. RhinoSource reviewed T-Mobile’s DataStax Enterprise architecture, configuration, data models, configuration and application code and made recommendations to improve overall performance and reliability.

RhinoSource helped T-Mobile set up SSL and Transparent Data Encryption (TDE) for the DataStax Enterprise clusters, to meet stringent enterprise security requirements, assisted with testing of node and data center failure and recovery scenarios, as well as investigated cluster replication and gossip issues, making recommendations that resolved the issues that were discovered.

RhinoSource coached the T-Mobile ops team through DataStax Enterprise cluster maintenance and node operations, general performance tuning, data export/import and educated the team on anti-patterns. RhinoSource guided T-Mobile system administrators through the setup of LDAP security integration for OpsCenter, helped configure automated OpsCenter backups to Amazon S3 for point-in-time recovery and provided best practices for setting up OpsCenter dashboards and proactive alerts.
