Application hosting

Core

Azure App Service

Managed web application hosting and configuration.

Key points

  • Managed hosting for web applications, APIs, and supported application stacks.
  • Apps run on App Service plan workers and have their own configuration.
  • Platform features include identity, domains, TLS, networking, slots, diagnostics, and backup.

Best-known use cases

  • Host a managed web API without guest OS administration.
  • Deploy a web application with staging slots and custom HTTPS.

What candidates often confuse it with

  • App Service vs VM: managed app platform vs customer-managed guest OS.
  • App Service vs Container Apps: plan/app model vs container environment/revision model.

Key takeaway

Use App Service for managed web workloads that benefit from built-in application operations rather than guest OS control.

Mode

Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-104. This lane counts multiple-choice and multiple-response items as exam-style practice. Ordering, matching, and case-study items are supplemental site exercises and do not count toward exam-style accuracy. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Intermediate-level scenario complexity rather than a Microsoft-published question rating.
