❓ FAQ

Is App Service a PaaS or IaaS?

PaaS (Platform as a Service). Microsoft manages OS, runtime, patches, and scaling. You deploy code and config.

Can I use App Service for production?

Yes. Enterprise customers run mission-critical apps on App Service. SLA is 99.95% for multi-instance deployments.

Can I scale App Service automatically?

Yes, both horizontally (more instances) and vertically (larger instances). Autoscaling rules based on CPU, memory, or request count.

What is the difference between App Service Plan and Container Registry?

App Service Plan is your hosting tier (compute). Container Registry stores Docker images. You can host Docker containers on App Service using images from Container Registry.

Can I connect App Service to my on-premises database?

Yes, via Hybrid Connections or Azure Virtual Network integration. Requires VPN or ExpressRoute for secure connectivity.

How much does App Service cost?

Pricing tiers from free ($0) to premium ($100+/month per instance). Free tier has limitations (no custom domains, 1 GB storage). Shared tier is very affordable ($10-50/month).
