A Varnish Software Case Study
Morningstar, a global provider of independent investment research and real‑time market data for millions of instruments, needed to guarantee data freshness across multiple servers and datacenters. The company required a simple, shareable purging solution that could deliver at least 2,000 cache deletions per second, maintain consistency for developers and ops teams worldwide, and free up resources used by earlier purging processes.
They deployed Varnish Administration Console (VAC) with its Super Fast Purger — a RESTful, distributed purging hub that issues authenticated (HMAC) purge requests and supports ACLs, grouping and HTTP keep‑alive. In testing the purger exceeded requirements (peaking at 60,000 req/s and 4,000 req/s on a constrained virtual setup), raised cache hit rates from 70% to 90%, improved global data consistency, and freed resources for other tasks.
