Case Study: Mouser Electronics achieves zero downtime maintenance and active/active data center availability with ScaleArc

Mouser Electronics Stays Online with Active/Active Data Center Operations and Zero Downtime Maintenance from ScaleArc

Mouser Electronics, a global eCommerce distributor of semiconductors, needed to ensure continuous uptime as minutes of website downtime cost thousands in lost revenue. The company faced the challenge of boosting performance and availability for its mission‑critical ordering application, overcoming an unexpected primary database server failure without customer impact, and moving from an active/standby to an active/active database tier across two data centers.

Mouser deployed ScaleArc with SQL Server 2014 AlwaysOn to automate failover, steer reads and writes across sites, and buffer queries during primary failover. The solution delivered zero‑downtime maintenance and automatic cross‑data‑center failover (no outages or dropped sessions during a hard primary failure), served 40% of queries from cache to reduce DB load, and eliminated maintenance windows—protecting thousands of dollars per minute in potential lost revenue.
