Case Study: NASDAQ achieves zero downtime infrastructure migration with ScaleArc

Nasdaq Puts Stock in ScaleArc to Enable a Zero Downtime Environment

Nasdaq, the global exchange operator that powers more than 70 marketplaces and handles one in ten securities transactions worldwide, faced a major infrastructure challenge: migrate thousands of databases and applications from a legacy network to a new environment within six months while maintaining zero downtime for 24x7 trading systems.

To mitigate risk, Nasdaq deployed ScaleArc to create a transparent abstraction layer between applications and databases, allowing front-end and back-end migrations to proceed independently and without code changes. The phased approach completed the network migration on schedule with no service interruptions, and delivered ongoing benefits—query caching cut direct database traffic, logging and analytics exposed non‑optimized queries, and overall uptime and performance improved.
