Case Study: Waoo achieves doubled streaming capacity and builds a DIY CDN with Varnish Software

Waoo - Customer Case Study

Waoo is a Danish national content and fiber‑broadband provider delivering TV, internet, telephony and OTT video services. Rapid growth exposed limits in their streaming infrastructure—initially only 1–2 GB of capacity—so they needed to scale performance to serve many devices and both internal and external customers across different networks.

Waoo deployed Varnish Cache and built a custom DIY CDN using VCL customizations and a redirection service to route traffic by network, boosting cache hit rates and streaming capacity. The result: they avoided a 150–200% cost increase, would have needed at least twice their production capacity without Varnish, and saved significant build costs by running the CDN on commodity software; they are now moving to Varnish DIY CDN with professional services and management tools for further optimization.
