Global Telco Freed From Cloudera HBase, 40% TCO Reduction and Under 10ms Latency
A cloud-native digital commerce leader providing high-velocity converged charging systems for global Telco operators needed to migrate from licensed Cloudera HBase to open-source Apache HBase to eliminate vendor lock-in and reduce massive licensing overhead. Escalating costs and rigid upgrade cycles were hindering agility in 5G hyper-scaling. Billions of real-time transaction events demanded source-code level tuning for ultra-low latency. Applying its AI-First approach, Ksolves executed a zero-downtime migration of 2.5 PB+ to a 50+ node open-source Apache HBase cluster, delivering under 10ms P99 latency, 40% TCO reduction, and 100% SLA adherence throughout.
- The Bottleneck: Escalating Cloudera licensing costs and rigid upgrade cycles hindered agility in 5G hyper-scaling. The team could not cherry-pick or backport Apache HBase features without waiting for vendor release cycles.
- Dependency Risks: Reliance on proprietary Cloudera Manager increased long-term operational risk. Losing vendor tooling required building a new observability suite from scratch.
- The Scale: Billions of real-time events demanded source-code level architectural tuning. Standard configurations could not sustain under 10ms P99 latency at this volume.
- Replacing Proprietary Vendor Tools: Losing Cloudera Manager required building new monitoring suites on Prometheus and Grafana to maintain equivalent operational visibility.
- Achieving Zero-Downtime Migration: Moving 2.5 PB+ of live telco data needed complex, timed Snapshot-and-Sync frameworks to avoid disrupting live 5G applications.
- Massive Transactional Scale and Tuning: Handling billions of real-time events required deep, source-code level tuning to maintain ultra-low latency and minimise G1GC pauses.
- Security Re-Integration: Transitioning from Cloudera required manual re-mapping of Kerberos authentication and Ranger-based RBAC policies without the Cloudera Manager layer.
- High Costs and Ecosystem Rigidity: Rising licensing costs and inflexible upgrade cycles prevented the team from responding to operational requirements in real time.
Ksolves executed the full migration from Cloudera HBase to open-source Apache HBase using a phased Snapshot-and-Sync approach, keeping live 5G applications uninterrupted. Source-code-level tuning met ultra-low latency requirements. Prometheus and Grafana replaced proprietary tooling. Kerberos and Ranger RBAC maintained enterprise security. The governing principle: 100% open-source at every layer with no remaining Cloudera dependency.
- Zero-Downtime Migration via Snapshot-and-Sync: Safely moved 2.5 PB+ of live telco data in controlled phases without interrupting live 5G charging and billing applications at any point.
- Custom Observability With Prometheus and Grafana: Replaced Cloudera Manager with a custom monitoring suite covering RegionServer health, Zookeeper quorum stability, latency percentiles, and TPS metrics.
- Source-Code Level Performance Optimisation: Off-Heap Read/Write Paths, custom BucketCache to minimise G1GC pauses, and HDFS short-circuit reads achieving under 10ms P99 latency at billions of daily events.
- Security Re-Integration via Kerberos and Ranger: Manually hardened the open-source cluster by re-mapping Kerberos authentication and implementing Ranger RBAC policies without Cloudera Manager.
- Open-Source Stabilisation and MTTR Improvement: 100% open-source Apache HBase eliminates licensing costs and stabilises MTTR via direct RCA, ensuring long-term 5G scaling agility without vendor dependency.
Technology Stack
| Category | Technology |
|---|---|
| Migration | Snapshot-and-Sync Framework |
| Observability | Prometheus + Grafana |
| Performance | Off-Heap Paths + BucketCache + HDFS Short-Circuit Reads |
| Security | Kerberos + Apache Ranger RBAC |
| Stabilization | Apache HBase Open Source (50+ Nodes) |
- 40% Annual TCO Reduction: Elimination of Cloudera licensing fees delivered 40% annual TCO reduction. Open-source Apache HBase scales cost-linearly as transaction volumes grow.
- Under 10ms P99 Latency at Massive Scale: Source-code level tuning achieved under 10ms P99 read/write latency at 1 TB+ daily throughput across billions of real-time events.
- 2.5 PB+ Migrated With Zero Downtime: Phased Snapshot-and-Sync framework moved the full telco data estate without a single interruption to live 5G charging and billing applications.
- 100% SLA Adherence Throughout: 100% SLA maintained across the full migration and stabilisation period. No SLA breach recorded across the entire engagement.
- Full Operational Freedom From Vendor Lock-In: Team can now cherry-pick Apache HBase features, resolve RegionServer and Zookeeper issues via direct RCA, and scale for 5G without proprietary Cloudera constraints.
“The Cloudera licensing cost was high, but the real constraint was the upgrade cycle rigidity. Moving to open-source Apache HBase gave us both the cost reduction and the operational freedom to tune the platform at source-code level for 5G hyper-scaling. Ksolves delivered the migration without a single disruption to our live charging systems.”

A cloud-native telco monetisation platform carrying billions of daily charging events, constrained by Cloudera HBase licensing and rigid upgrade cycles blocking 5G scaling, was transformed through Ksolves Big Data services. 2.5 PB+ migrated to 50+ node open-source Apache HBase with zero downtime. Under 10ms P99 latency delivered. 40% TCO reduction achieved. 100% SLA maintained. Prometheus and Grafana replaced Cloudera Manager. Kerberos and Ranger secured the cluster. Zero remaining proprietary dependency.
Is Proprietary Licensing Overhead and Ecosystem Rigidity Impeding Your 5G Hyper-Scaling Agility?
