Case Study: CallHealth achieves a secure, scalable, highly available healthcare platform with Microsoft Azure

CallHealth - Customer Case Study

CallHealth is a technology‑powered healthcare company in India that built an integrated virtual-and-mobility platform to deliver “everything about health” to patients at home. As the service moved from on‑premises alpha to an 8‑million‑user beta, the team faced scaling limits, risk of unplanned downtime during peak traffic, strict data‑residency and security requirements, and the need for an affordable, compliant hosting model.

CallHealth migrated its production, storage and archival to Microsoft Azure, using India‑based datacenters, automated deployment, and pay‑as‑you‑use billing. Azure provided auto‑scaling, vertical and horizontal capacity sizing, HIPAA/ISO‑compliant security, and a 99.99% availability SLA, enabling seamless scalability, assured data residency and high availability at a predictable cost.
