Case Study: Yo achieves a scalable, reliable mobile backend to send millions of notifications with Amazon Web Services (AWS)

Yo - Customer Case Study

Yo is a social messaging app for iOS, Android, and Windows that surged to 1 million users within four days of its 2014 launch. Initially built on a third‑party platform, the company needed a more scalable, reliable backend to support rapid growth and deliver hundreds of thousands of messages to users.

Yo migrated its backend to AWS, using Amazon SNS for notifications, EMR for processing usage data, EC2 for utility services, and S3 for storage. This architecture gave Yo global, on‑demand capacity, improved reliability and configurability, reduced downtime, and enabled the app to send notifications at scale while enhancing the user experience.
