CASE STUDY

Enterprise-Grade Reliability & DevSecOps Transformation

Ensuring 99.99% availability for mission-critical insurance systems via hybrid cloud & DevSecOps.

Client:

LSN
(Technology Provider for the Insurance Sector)

End-Client:

Leading Insurance Company in Poland

Core Services:

DevOps, High Availability (HA), 24/7 Managed Services

Infrastructure:

Hybrid (On-Premise + Azure)

Key Metric:

99.99% Service Uptime

Executive Summary

LSN specializes in developing and maintaining complex IT ecosystems for financial and insurance institutions. For their key client, one of Poland's largest insurers, any system unavailability directly translates into a complete halt of sales across a nationwide agent network. Professnet assumed full responsibility for the operational layer, implementing a DevSecOps model and High Availability (HA) architecture. The collaboration resulted in achieving 99.99% availability while simultaneously accelerating the software release cycle by 60%.

Challenge: The Stability vs. Agility Paradigm

Operating within the highly regulated and competitive insurance sector, LSN faced a dual challenge necessitating a compromise between operational stability and rapid innovation:

Solution: Integrated DevSecOps & Hybrid Cloud Architecture

Professnet implemented a comprehensive support model, acting as a strategic technological partner rather than a mere service provider. The solution was grounded in ITIL Service Operation standards and the Azure Well-Architected Framework.

01 Phase

Resilient Infrastructure (High Availability & Redundancy)

We architected a fault-tolerant environment to eliminate Single Points of Failure (SPOF):

Hybrid Orchestration:

Management of Hyper-V clusters and containerization platforms (Kubernetes, Docker Swarm) to ensure optimal resource utilization.

Network Redundancy:

Implementation of BGP protocols and SD-WAN, complemented by Azure Express Route, ensuring uninterrupted connectivity between data centers and the cloud.

Disaster Recovery:

Deployment of rigorous DR procedures to guarantee business continuity in catastrophic scenarios.

02 Phase

Process Automation (CI/CD & DevOps)

We assumed ownership of the code repositories and deployment pipelines, bridging the gap between Development and Operations:

Pipeline Standardization:

Utilization of GitHub Actions, GitLab CI, and Jenkins to automate the Build/Test/Deploy stages.

Efficiency:

Standardization of environments allowed for frequent, reliable updates without service degradation.

03 Phase

Proactive Observability & Security

Transitioning from reactive support to proactive monitoring:

Observability Stack:

Implementation of real-time monitoring for logs, metrics, and alerts, integrated with SIEM/SOC systems.

Vulnerability Management:

Regular vulnerability scanning and systematic system patching (Patch Management) to mitigate security risks.

Professnet Expert on the Project

"In the insurance industry, maintenance is not just about keeping the lights on; it is about ensuring operational elasticity. By integrating BGP routing and SD-WAN with our Kubernetes clusters, we created an infrastructure that is self-healing. If a node fails, the traffic is instantly rerouted, making the incident transparent to the end-user—the insurance agent selling a policy."

Key Results & Business Impact

The partnership delivered measurable improvements in operational stability and development velocity.

Operational Excellence

Maintained 99.99% availability for over 50 critical systems through full redundancy and proactive monitoring.

Accelerated Time-to-Market

60% reduction in deployment and update times due to CI/CD pipeline automation.

Risk Mitigation

45% decrease in critical incidents achieved through preventive maintenance and automated alerting mechanisms.

Developer Productivity

30% increase in development team efficiency, allowing LSN engineers to focus on code rather than infrastructure troubleshooting.
