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
