Case Study: Bazaarvoice achieves scalable, cost-efficient logging to monitor 5.4 billion monthly page views with Logz.io

How Bazaarvoice Monitors 5.4 Billion Monthly Page Views with Logz.io

Bazaarvoice connects brands and retailers with shoppers across 5,700 sites, delivering personalized experiences that generate roughly 5.4 billion page views monthly and billions of shopper signals. Their distributed Java/Scala/Python services run on thousands of EC2 instances and produce highly variable log volumes — including large bursts — which made their previous logging solution prohibitively expensive and inflexible, so they needed a scalable, cost-efficient, privacy‑aware logging platform.

Bazaarvoice chose Logz.io for its ELK‑based, open-source stack, flexible overage plan and hands‑on support, and integrated it with an in‑house log aggregator, grok parsing, Kibana dashboards, and alerting to PagerDuty and HipChat. The result: reliable multi‑AZ data segregation, a utilization dashboard and alerts for spikes, daily ingestion around 60 GB (with capability to handle 400 GB bursts), and more than 80 users monitoring 50+ services — improving root‑cause analysis, real‑time troubleshooting and overall visibility while controlling costs.
