Case Study: Arriva Bus achieves SQL Server optimisation and reduced licensing costs with Node4 Ltd

Arriva Bus Working with Node4 has helped Arriva to drive their database design forwards

Arriva Bus, a major UK public transport operator, was struggling with a growing and organically built SQL Server estate that had led to database performance issues, licensing inefficiencies, and compliance concerns. Arriva turned to Node4 Ltd for advice and support, including help with a critical EPOS application database and wider SQL Server estate optimisation.

Node4 Ltd assessed the application, queries, indexing, and infrastructure, then recommended and helped implement a modernised, consolidated SQL Server design, including an upgraded SQL Server Always On Availability Group built on a multi-site 3-node cluster. The result was improved database performance, significant infrastructure consolidation, and reduced software licensing costs, while Node4 Ltd continued to provide 24/7 managed service, monitoring, and ongoing environment modernisation across Azure and internal data centre platforms.
