Azure Cloud Infrastructure & DevOps: Zero-Downtime Migration with Full CI/CD
From manual, risky deployments to fully automated infrastructure — with zero downtime during the cutover.
Single-server setup with no automation and no monitoring
The legacy application was deployed on a single-server setup managed by an external IT vendor, with no automated deployment pipeline, no monitoring, no staging environment, and manual deployments that introduced risk and downtime. The client's IT team had limited Azure experience, and the organization required the new platform to run entirely within a client-owned Azure tenant for IP sovereignty and compliance.
17 Azure resources provisioned in a single Terraform run with zero downtime
We designed and provisioned a complete Azure production environment using Infrastructure-as-Code (Terraform), deploying 17 resources in a single automated run. The architecture included Azure App Service (B2, 2-core) running the Python API via Docker, Azure Static Web Apps hosting the React frontend, Azure Database for PostgreSQL Flexible Server (B2ms, 2 vCores), Azure Key Vault for secrets management, and Application Insights for performance monitoring.
A full CI/CD pipeline was built in Azure DevOps with four automated stages: code quality (Ruff linter), automated testing (680+ tests), artifact build, and zero-downtime deployment to production. Every merge to main triggered automatic deployment of both API and frontend. Feature branches ran lint, test, and build stages without deploying. Browser cache-busting headers were added to ensure users always received the latest frontend build without manual hard-refreshes.
We also coordinated with the client's IT team to configure Azure subscription access, DevOps user permissions, and static IP whitelisting for legacy database connectivity — managing the entire handoff process on behalf of a non-technical client.
Infrastructure as Code: Terraform provisioned all 17 Azure resources in a single automated run — App Service, Static Web Apps, PostgreSQL Flexible Server, Key Vault, and Application Insights.
CI/CD Pipeline: Four-stage Azure DevOps pipeline: code quality (Ruff linter) → automated testing (680+ tests) → artifact build → zero-downtime production deploy. Automated on every merge to main.
Containerization: Docker-containerized Python API running on Azure App Service B2 (2-core). Azure Static Web Apps hosts the React frontend independently.
Secrets & Monitoring: Azure Key Vault for all secrets management. Application Insights for performance monitoring and observability.
Client Handoff: Managed the full Azure subscription access configuration, DevOps user permissions, and static IP whitelisting for legacy database connectivity on behalf of a non-technical client team.

Fully automated, production-grade infrastructure from day one
The client went from manual, risky deployments to a fully automated, monitored, and reproducible cloud environment — with IP sovereignty and compliance requirements satisfied.
