Modernizing Telecom Data Management
TMForum Compliant
As telecommunication ecosystems expand, data silos and rigid architectures can severely bottleneck business decision making. In this international initiative spanning Chile and Peru, Crossjoin acted as the trusted technology partner to migrate and modernize a major telecom operator's legacy data environment, turning operational friction into competitive advantage.
Challenge
The client faced a highly restrictive data ecosystem that slowed business agility. The challenge was to modernise the platform by migrating from AWS to an OCI Lakehouse, reducing costs while creating a more scalable, efficient, and flexible data foundation.
Critical operational bottlenecks included:
- High Infrastructure Costs: The existing data architecture drove high infrastructure costs and limited cost-efficient scalability.
- Slow Time-to-Insight: Critical business data and updated reports were only available after 10:00 AM, delaying access to key insights.
- Fragmented Data Landscape: Data silos limited a unified view of information across the business.
- Rigid Architecture: A heavily SQL-dependent environment limited flexibility for data exploration and constrained cloud migration options.
