Case Study: Cognizant keeps Virginia toll traffic flowing with FlashGrid on AWS

Cognizant and FlashGrid Keep Traffic Flowing Smoothly Under Virginia’s Elizabeth River

Cognizant was engaged by Elizabeth River Crossings (ERC) to address significant challenges with its legacy digital tolling system, which was causing billing delays and operational issues due to an overwhelmed on-premises data center. The IT services firm partnered with vendor FlashGrid to migrate the mission-critical Oracle RAC database to AWS, requiring a solution that ensured absolute high availability with zero tolerance for downtime.

The solution was implemented using FlashGrid Cluster software, which facilitated the complex cloud migration and enabled a cost-effective disaster recovery strategy using infrastructure as code. With support from FlashGrid, the migration was completed on a tight deadline. The new system increased Oracle RAC performance by 90%, cut disaster recovery costs by 70%, and has operated with no significant downtime for over three years.
