App Service custom domain
An App Service custom domain lets people use your real website name instead of the default azurewebsites.net address. You prove that you own the DNS name, point DNS records at the web app, and add the hostname to App Service. The setting is simple on the surface, but production success depends on DNS propagation, ownership verification, TLS certificates, redirects, and whether traffic also passes through Front Door, Traffic Manager, or another edge service. Plan it like a release.

Premium v4 App Service tier
Premium v4 is the App Service tier you choose when a production web app, API, or container needs stronger dedicated workers than older premium tiers provide. It is still App Service, so Azure manages the platform, patching, load balancing, deployment slots, and scale controls. The difference is the worker profile: faster processors, NVMe-backed local storage, and memory-optimized options. Use it when measured CPU, memory, startup, or local I/O pressure justifies a larger plan, not as a blind fix for every slow request.

FTP deployment
FTP deployment is an Azure App Service deployment method where application files are uploaded to a web app through FTP or FTPS publishing endpoints. Teams use it to support simple or legacy file-based releases when a full CI/CD pipeline, container image, or ZIP deployment flow is not available. In daily Azure work, it shows up when engineers publish static content, migrate an older web app, recover a small site, rotate deployment credentials, or disable basic publishing after modernization. It is not source control, a build pipeline, a secure secret-management strategy, or the preferred deployment method for regulated production systems.

It should be reviewed through security, reliability, operations, cost, and performance lenses before production changes.
