Apollo Hospitals at Google Cloud microservices zero-downtime

Achieving zero downtime migration of a complex micro services application to Google Cloud for Apollo Hospitals

One of India’s largest multidisciplinary healthcare systems, it offers online doctor consultations, home diagnostic tests, and online pharmacy to make healthcare affordable and accessible

This blog describes how it migrated a critical 24×7 national application with 97 services and 40+ SQL databases to Google Cloud with zero downtime

The application integrates SQL and NoSQL databases, Redis, VMs, Kubernetes, load balancers, WAF, and third-party public endpoints

Modern automation and Infrastructure as Code (IaC) interventions would improve robustness and scale

Apollo Hospitals, Searce, and Google Cloud teams collaborated on development, testing, deployment, and monitoring, which helped the migration project succeed

Apollo Hospitals is also expanding its AI-powered solution partnership beyond the Clinical Decision Support System (CDSS) built with Google Cloud Consulting AI teams
