Case Study: SoundBus achieves secure, scalable global Oi‑Fi deployment and cost savings with Amazon Web Services

SoundBus Technologies Co., Ltd. - Customer Case Study

SoundBus Technologies, founded in 2014, developed patented Oi‑Fi ultrasonic “sound codes” that link users to services but posed major IT challenges: secure, long‑term storage of billions of tiny files, ultra‑low‑latency decoding across billions of password rules, the ability to absorb massive, short‑term traffic spikes, reliable 24/7 operation for night‑time services, strong content‑filtering and network isolation, and global scalability — all on a startup budget.

SoundBus moved its infrastructure to AWS, using Amazon S3 for durable encrypted storage, ELB with Auto Scaling and CloudWatch for traffic surges and availability, DynamoDB to front‑cache rule lookups for fast decoding, and Amazon VPC plus other AWS services (EC2, RDS, SQS, CloudFront) for security and global reach. The result: lower capital and operational costs, faster product innovation, stable 24/7 service, and rapid customer wins (including China UnionPay and Coca‑Cola) with a scalable platform that supports ongoing global growth.
