Case Study: Sestra Systems achieves real-time, low-latency, scalable IoT control of beverage dispensers with Hitachi Vantara (REAN Cloud)

Achieve IoT based Cloud Solution for Smart Beverage Dispensing

Sestra Systems, which turns beverage taps into IoT‑connected dispensers, needed a low‑cost, scalable way to monitor and control distributed devices around the world. The company required 24x7 visibility, per‑pour diagnostic logs, sub‑second command execution, secure connectivity in locked environments, and offline functionality for deployments with intermittent or no internet (e.g., cruise ships). Hitachi Vantara (through its REAN Cloud IoT Services) was engaged to meet these constraints.

Hitachi Vantara’s REAN Cloud modernized Sestra’s application using cloud‑native AWS IoT services, a lightweight MQTT agent (<1 MB) with a local device database, serverless ingestion and device provisioning, TLS security, and edge/offline support. The solution delivered sub‑second command latency, continuous remote visibility and per‑pour diagnostics, faster fault diagnosis and resolution, and a low‑cost, reusable architecture that scales as Sestra grows — enabling reliable operation even in low‑connectivity environments.
