The Challenge
A healthcare technology company needed to migrate a production multi-service application off
Google Cloud and onto Microsoft Azure. The work spanned application services, PostgreSQL
databases, networking, secrets, CI/CD pipelines, and frontend applications, and had to deliver
a platform built for security, reliability, and scale without disrupting live operations.
Complex Multi-Service Platform
A production healthcare application made up of many interconnected services and frontend applications.
Production Database Modernization
PostgreSQL databases that had to be migrated and modernized without data loss or downtime.
Security & Networking Requirements
Strict security and networking demands for a regulated healthcare environment.
Environment Consistency
Dev, QA, and Prod environments that needed to stay consistent and reproducible.
Deployment & Operational Efficiency
Manual processes that slowed deployments and made operations harder to manage.
The Solution
We ran the migration in phases, inventorying the existing Google Cloud environment, mapping
each service to its Azure equivalent, and rebuilding the platform as reusable infrastructure
as code with automated deployments.
Inventory & Service Mapping
Analyzed and mapped more than 30,000 cloud resources in Google Cloud, then mapped each Google Cloud service to its equivalent Azure service and designed the target architecture.
Google Cloud
Inventoried the existing environment and mapped every resource.
Terraform
Provisioned Azure with reusable infrastructure-as-code modules.
GitHub Actions
Automated builds, tests, and deployments across environments.
Microsoft Azure
Final cutover to a secure, scalable production platform.
A phased path from Google Cloud to Azure, rebuilt as repeatable infrastructure with automated delivery.
Terraform Infrastructure
Built reusable Terraform modules for networking, databases, secrets, and application services, making every environment consistent and reproducible.
Automated Deployments
Implemented GitHub Actions pipelines for both application and infrastructure deployment, replacing manual steps with repeatable workflows.
Data Migration
Migrated PostgreSQL databases and application data to Azure with validation to protect data integrity.
Production Cutover
Executed the final migration and DNS cutover with validation and monitoring to keep the live platform healthy.
Results
The platform now runs on Azure as repeatable infrastructure as code, with hardened security,
automated delivery, and centralized monitoring across Dev, QA, and Prod.
Infrastructure as Code
Terraform-managed infrastructure with reusable modules and consistent, version-controlled, repeatable environments.
Hardened Security
Private PostgreSQL access, SSL-enforced database connections, Key Vault secret management, and RBAC least-privilege access.
Automated Operations
GitHub Actions CI/CD with automated builds, tests, and releases for faster, more reliable, more consistent deployments.
Centralized Monitoring
Centralized logging and monitoring through Azure Log Analytics, with standardized workflows.
Simplified Configuration
Environment variables reduced from hundreds to fewer than ten, with secrets cleanly separated from application config.
