Case Study: Shazam achieves instant content updates and scalable mobile performance with Fastly

How the world's premier audio recognition technology uses Fastly to accelerate their mobile app for 100M users who "Shazam" over 20M times daily

Shazam, the leading audio-recognition app with hundreds of millions of downloads and over 100 million monthly active users, needed infrastructure that could scale with rapid growth, minimize mobile network latency, and ensure users always saw up-to-date song info, artwork, and campaign content — even during high-traffic events and last-minute ad changes.

Shazam implemented Fastly’s mobile-optimized CDN, using instant purge, surrogate keys and real-time configuration via API/UI to cache APIs and dynamic content, reduce origin load, and deploy updates instantly. The result was faster, more reliable delivery closer to users, smoother handling of traffic spikes, quicker campaign turnarounds, and actionable real-time logs and analytics that freed engineering resources for innovation.
