Shopzilla's Site Redo - You Get
summary
Shopzilla rebuilds a monolithic mod_perl site into a Java service-oriented stack with Oracle Coherence caching, an A10 proxy for side‑by‑side rollouts, a CDN with a non‑cookie image subdomain, and an AB/multivariate framework. SLAs target 1.5s full page, 650ms server, 95th percentile, 0% errors; services aim for ~200–250ms. Results: 7s to 1s page loads, average server <200ms, 10% conversion lift, pageviews +25%, infrastructure halves, availability 99.7% to 99.94%, and 120% SEM sessions increase in the UK.
