Case Study: Boozt Fashion achieves high-performance, scalable e-commerce and reduced infrastructure costs with Varnish Software

Boozt Fashion Uses Varnish Api & Web Acceleration To Deliver High-performance, Personalized E-commerce User Experiences And Maintain Lean, Efficient Operations

Boozt Fashion is a fast-growing Nordic e‑commerce retailer (about 5 million visits per month and SEK 1.6 billion transactional revenue in 2016) that runs a very lean tech stack—just a few powerful servers and a small development team. The company needed to deliver fast, personalized shopping experiences and scale reliably for traffic spikes (e.g., Black Friday) without adding significant infrastructure or staff.

Boozt deployed Varnish Cache and subscribed to Varnish API & Web Acceleration (VAC, Varnish High Availability, enhanced invalidation and expert support), tuning VCL to handle dynamic and personalized content. The result was major performance and scalability gains—avoiding roughly 3× the computing power for peak events, reducing failover recovery from over an hour to about 15 minutes, lowering ops time to about an hour a week, and maintaining high site performance and stability during peak traffic.
