SSO AND IAM SYSTEM FOR A B2B PLATFORM

Inter Cars S.A. is the largest distributor of spare parts for passenger cars, vans, and trucks in Central and Eastern Europe. The company’s offering also includes workshop equipment as well as motorcycle parts and tuning accessories. Inter Cars has been listed on the Warsaw Stock Exchange since May 2004.

The implementation began with an analysis phase and the design of integration architecture with WSO2 IS. During this analysis, we presented the client with the optimal course of action to ensure full delivery of the project scope and achievement of its objectives.

Following intensive analytical workshops, key documents were produced including the Platform Technical Design and the Low-Level Design (LLD) Architecture. In the next phase, our task was to deploy the system in the Inter Cars environment. After delivering and installing the system, we carried out the necessary configuration, parameterization, and customization work to align the software with Inter Cars’ specific requirements. In parallel, both teams were working to prepare for the complex testing phase.

Once the system was formally accepted, comprehensive performance, security, and operational readiness testing began. Both Savangard and the client engaged additional resources to meet the demands of this critical phase. The final stage was the Stabilization Period, during which the implemented system was launched into the production environment.

During the implementation, we encountered a significant challenge in meeting the required system performance targets. All tests were passing without issues until we identified that the system was failing to meet the throughput assumptions.

To meet the client’s expectations, we engaged an additional WSO2 support team. After several weeks of optimization and testing, we successfully achieved a stable throughput of 200 logins per second, along with all throughput and concurrent login requirements across all active markets.

The introduction of the WSO2-based solution significantly improved the performance and reliability of the Inter Cars system. The required level of scalability was achieved, and stable system operation was ensured – eliminating the disruptions and failures that had previously occurred on a regular basis. The deployed system was launched into the production environment and is now successfully operating across 21 countries.
