Case Study: Choxi achieves reliable, zero-downtime scaling for massive holiday spikes with ClustrixDB (Clustrix)

Reliability and Availability with fast growth in the cloud

Choxi (formerly nomorerack.com) is a rapidly growing U.S. e‑commerce flash‑sale retailer — reporting 1,023% year‑over‑year revenue growth and ranking as the 2nd fastest‑growing e‑tailer on Internet Retailer’s list. The business experiences extreme traffic peaks (15–20x in holidays and a 600% Cyber Monday sales spike) and was running on AWS RDS where single‑master limits, slow writes, disk I/O problems, poor visibility, slow vendor support, and multi‑hour outages (costing $20k–$60k per hour) threatened revenue and availability.

Choxi moved to ClustrixDB’s scale‑out SQL running on AWS/DirectConnect and gained 24/7 enterprise support, query tuning, and the ability to use all nodes for queries. Using Clustrix’s flexible scaling, the cluster grew from 6 to 14 nodes for Cyber Monday with no downtime, later to 18 nodes for the holidays, handled massive concurrency without slowing or crashing, and helped Choxi capture record traffic and a 60% increase in net revenue.
