- Web applications (ASP.NET, Node.js, Python, Java)
- REST APIs and microservices
- Mobile app backends
- Static website hosting
- Production applications requiring scale
- Applications needing auto-scaling
- Multi-region deployments
- Containerized applications
Quick Start
Minimal working example:
bash# Login to Azure az login # Create resource group az group create --name myapp-rg --location eastus # Create App Service Plan az appservice plan create \ --name myapp-plan \ --resource-group myapp-rg \ --sku P1V2 \ --is-linux # Create web app az webapp create \ --resource-group myapp-rg \ --plan myapp-plan \ --name myapp-web \ --deployment-container-image-name nodejs:18 # Configure app settings az webapp config appsettings set \ --resource-group myapp-rg \ --name myapp-web \ --settings \ // ... (see reference guides for full implementation)
