Modernization and Expansion of the IT Infrastructure and Data Center

Solution and Business Value

Senseti implemented a Data Center scaling and modernization project aligned with current operational needs, risk mitigation, and long-term development strategy:

• Deployment of new scalable and high-availability infrastructure based on HPE, Fortinet, Aruba, and APC solutions.
• Implementation of a Fortinet NGFW high-availability cluster for perimeter and network security.
• Deployment of a new primary storage system with migration of live services.
• Repurposing and modernization of legacy storage for backup workloads.
• Introduction of VMware load balancing within the virtual infrastructure.
• Integration of the legacy Fortinet appliance as a dedicated gateway for web application and API protection.
• Improved availability, optimized resource utilization, and enhanced security across the entire IT environment.

The project strengthened the digital platform of the “Visa” Department, establishing a resilient foundation for future expansion and continued digital transformation within municipal services.

How the Solution Was Implemented

The modernization project was executed in phases, ensuring minimal disruption to ongoing services:

Phase 1. Audit and Consulting

A comprehensive assessment of the existing IT infrastructure was conducted. Performance bottlenecks were identified, system mapping was completed, and current workload levels were evaluated.

Phase 2. Architecture Design

A new Data Center architecture was developed with a focus on scalability, high availability, and enhanced backup requirements.

Phase 3. Equipment Procurement

Deployment included HPE servers, a Fortinet NGFW high-availability cluster, a new primary storage system, Aruba core switches, and APC uninterruptible power supply units.

Phase 4. Integration and Migration

VMware-based clustering and virtual machine load balancing were implemented. Live data migration was performed, and a new backup architecture was configured. Additionally, an updated network architecture was introduced along with strengthened security policies.

Phase 5. Testing and Ongoing Support

Load testing and failover validation were completed, security policies were fine-tuned, and the project was transitioned into ongoing managed support by the Senseti team.
