Case Study: Bleacher Report achieves massive scale for real-time push notifications with Iron.io

Delivering Massive Sports Scores & News

Bleacher Report, a leading sports news publisher and maker of the Team Stream mobile app (over 12 million downloads), needed to deliver real-time scores, news and alerts to millions of users without service interruptions. Rapid growth and peak events routinely overwhelmed their self‑hosted worker cluster (limited to ~60 servers), creating backlogs and threatening uptime and timely delivery of push notifications.

Bleacher Report migrated to Iron.io’s IronWorker for cloud-based asynchronous task processing, deploying a working prototype in days and retiring their old infrastructure within weeks. The move enabled on‑demand, highly concurrent notifications (peaks of ~3,000 workers, typically 500), dramatically improved alert times, reduced operational overhead and costs, and allowed the team to scale painlessly and focus on product features while delivering billions of push notifications reliably.
