Case Study: Zync achieves millions of messages daily and instant, cost-effective scalability with Google Cloud Platform

Zync Delivering millions of business messages daily

Zync, a Sydney-based cloud messaging company founded in 2009, provides a self‑service platform (Upwire) for voice, SMS and email campaigns worldwide. Facing unpredictable, extreme workloads and a goal to be globally elastic without owning expensive data centers, Zync needed instant scalability, strong SLAs, real‑time campaign analytics and low operational overhead.

By building on Google Cloud Platform (App Engine, Compute Engine, BigQuery, Cloud Datastore, Cloud SQL, Stackdriver) Zync gained automatic autoscaling and real‑time analytics. The platform now delivers millions of SMS and emails daily, handles over 1,000,000 attempted voice calls per day, delivered 800,000 pre‑recorded calls in 10 hours without affecting other customers, and lets a seven‑person team offer reliable, cost‑effective global messaging with immediate campaign adjustments.
