Case Study: ZALORA achieves rapid scalability and faster product launches with Amazon Web Services (AWS)

ZALORA - Customer Case Study

ZALORA, founded in 2012 and the largest online fashion retailer in Southeast Asia, runs localized sites across eight markets with over 200,000 products. Rapid growth after launching its own brands created surging traffic that its hosted data‑center infrastructure couldn’t cost‑effectively scale—new servers took weeks to procure, capacity sat idle most of the year, and that slowed feature development and expansion.

ZALORA migrated fully to AWS by 2016, running core systems on Amazon EC2, S3, RDS and Redshift with Route 53, SES, CloudWatch and CloudFormation automating operations. The move scaled EC2 instances from a baseline of five to 400 (1,000+ at peaks), lets the company boost capacity up to 300% for sales and shut it down in minutes, and supports ~30 million monthly users. As a result, time‑to‑market for new products is up to three times faster, operational overhead is lower, and the business can innovate and expand more quickly.
