How Ksolves Secured 850K Daily Transactions for a Telecom Notification System With Zero Downtime
Overview

A major telecommunications operator in North Africa had built its customer notification mediation capability on an Apache NiFi cluster that processes up to 850,000 transactions every day. The platform managed all outbound customer notifications based on behavior and preferences and had been classified as business-critical infrastructure. There was one significant problem: the entire system had been built as a proof of concept by an internal team and had never undergone a formal architecture review, leaving performance bottlenecks, security gaps, and misconfigured flows running undetected in a live production environment.

 

With no support SLA, no incident-escalation path, no trained operations team, and no validated scalability roadmap, the operator was managing a revenue-critical platform without a safety net. Traffic was projected to scale from the current 850K transactions per day to millions as the CBiO 22 program accelerated, and the architecture had never been validated for that growth. The organization partnered with Ksolves, an AI-First Company, to conduct a formal architecture review, establish 24×7 support with defined SLAs, and deliver a structured training program for the internal operations team.

Key Challenges

The challenges faced by the client are as follows:

  • No Architecture Validation on Live Infrastructure: The NiFi cluster and all data flows were built as a PoC by an internal team and had never undergone a formal architecture review, leaving performance bottlenecks, security gaps, and misconfigured flows undetected in a production environment handling hundreds of thousands of daily transactions.
  • 850K Daily Transactions With No Downtime Tolerance: The notification mediation system was classified as business-critical. Any interruption would directly impact revenue and subscriber experience, making even a brief unplanned outage commercially unacceptable for the operator.
  • No Support SLA or Incident Response Mechanism: There was no defined SLA for incident resolution, no escalation matrix, and no 24x7 monitoring coverage, meaning production-critical failures had no guaranteed response path, and resolution timelines were entirely unpredictable.
  • Untrained Operations Team: The team responsible for managing the NiFi system lacked formal training in cluster management, flow monitoring, advanced troubleshooting, and performance tuning, creating compounding operational risk with every passing day.
  • Scalability Uncertainty as Traffic Grows: The architecture had not been validated for scalability from the current 700K to 850K transactions per day to the projected millions, leaving the operator exposed as subscriber volumes and notification use cases continued to expand under the CBiO 22 program.
  • Security and Compliance Gaps Not Assessed: NiFi Registry, ZooKeeper, and OS-level configurations on Red Hat Enterprise Linux had not been reviewed for security hardening, RBAC, or access controls in line with production standards, leaving the platform outside compliance baselines.
Our Solution

Ksolves, an AI-First Company, engaged with the client across three complementary workstreams: a structured Discovery and Gap Analysis phase, a continuous 24x7 Support service with defined SLAs, and a hands-on Training program. All three were delivered as an integrated engagement to address both the immediate operational risk and the long-term capability gap simultaneously.

  • Apache NiFi Cluster and Flow Review: Ksolves conducted a comprehensive audit of the existing NiFi cluster configuration, reviewing up to 3 production flows for performance, scalability, and security. The audit produced an actionable Gap Analysis Report with prioritized remediation recommendations covering back-pressure settings, throughput constraints, and flow dependency risks.
  • NiFi Registry and ZooKeeper Configuration Review: The NiFi Registry setup and ZooKeeper coordination layer were assessed to identify configuration risks, version compatibility issues, and alignment with production readiness standards, producing a documented remediation roadmap delivered to the client within the 30-working-day engagement window.
  • 24x7 Support Service with Defined SLAs: A structured support model was established with tiered severity response times. Critical issues are acknowledged within 30 minutes and resolved within 4 hours, providing the operator with a guaranteed incident-response path and a formal escalation matrix on first occurrence.
  • Operations and Maintenance Training Program: A structured training workstream was delivered covering NiFi cluster management, data flow monitoring, troubleshooting techniques, and performance tuning best practices, including hands-on exercises and customized learning materials designed to fully equip the internal team to manage the system independently.
  • Scalability and Performance Optimization Roadmap: As a direct output of the gap analysis, a validated set of optimization recommendations was produced to support scale-out from 850K to millions of daily transactions, including flow redesign guidance, cluster sizing recommendations, and a sequenced implementation plan aligned to the operator's growth timeline.

Results
  • Zero-Downtime Architecture Validated for 850K+ Transactions Per Day: The NiFi cluster was previously running as an unvalidated PoC with unknown performance limits and no production readiness sign-off. The gap analysis delivered a production-readiness certification with a prioritized remediation plan, confirming the architecture can sustain 850K transactions per day and providing a documented, sequenced path to millions of daily transactions as the CBiO 22 program scales.
  • 24x7 Incident Response Coverage Established for the First Time: The operator previously had no SLA, escalation matrix, or support mechanism of any kind. Production-critical failures had no guaranteed response path, and resolution times were entirely unpredictable. A defined SLA model is now in place, with critical severity acknowledged within 30 minutes and resolved within 4 hours, eliminating the unmanaged risk window that had existed since the platform went live.
  • 3 High-Risk NiFi Flows Reviewed and Optimized: All active production flows had previously run without any review. Misconfigured back-pressure settings and unvalidated flow dependencies had created latent failure risks across the notification pipeline. A detailed review of up to 3 production flows was completed, with documented optimization recommendations addressing backpressure, throughput, and dependency risks for each flow.
  • Internal Team Trained to Operate Independently: No in-house training had been conducted before the engagement, and the operations team lacked working knowledge of cluster management, troubleshooting procedures, and performance tuning. A structured training program covering NiFi cluster management, flow monitoring, troubleshooting, and performance best practices was completed, with hands-on labs and customized learning materials delivered to the team.
  • Security and Compliance Gaps Formally Documented and Remediated: NiFi Registry, ZooKeeper, and OS-level security configurations were previously unreviewed with no RBAC or hardening standards applied across any layer. A comprehensive security review was completed across all layers, and a remediation roadmap was delivered to the client's IT team within the 30-working-day discovery window.

Conclusion

Ksolves transformed an unvalidated and unsupported notification mediation platform into a production-certified NiFi environment with a structured support model, a fully trained internal operations team, and a documented remediation roadmap aligned to future scale. The operator moved from a system with no SLA, no architecture review, and no trained personnel to a governed, production-ready platform with a clear path to millions of daily transactions.

 

Zero disruption was maintained throughout the engagement. All analysis, review, and optimization work was delivered without interrupting live transaction flows throughout the 30-working-day program, preserving the platform’s unbroken service record that its subscribers depend on every day.

 

The governance model established during this engagement, including SLA definitions, escalation paths, and security standards, is directly replicable across other BSS and OSS data systems within the operator’s estate. For any enterprise running NiFi-based data infrastructure in production without formal review or support coverage, this engagement provides a proven delivery blueprint. As a trusted Apache NiFi Development Company, Ksolves brings the platform expertise and operational rigor needed to secure, validate, and scale mission-critical NiFi environments from day one.
