Describe cloud conceptsEasy

Which statement best describes Azure App Service?

Correct.

The concept

Managed application hosting takes the machine out of the picture. You supply code and a runtime choice, and the provider handles capacity, patching and the operating system beneath it.

Why this answer

The source states App Service lets you run web applications, mobile back ends, and RESTful APIs without worrying about managing the underlying infrastructure, matching this option exactly.

  • Correct: this is the core definition of App Service given in the overview.
  • BDescribes an IaaS virtual machine service, not the PaaS web hosting model App Service provides.
  • CDescribes a managed database service such as Azure SQL Database, not App Service.
  • DDescribes a network security appliance, unrelated to App Service's web-hosting purpose.
  • EDescribes a storage tier concept, not a compute/web hosting platform like App Service.

Sample question 2 of 3

Describe cloud conceptsHard

An architect is comparing Azure App Service and Azure Functions for a workload made up of short-lived, event-triggered tasks with highly variable execution frequency, rather than a continuously running web front end. Which service type better matches this workload pattern?

Sample question 3 of 3

Describe cloud conceptsHard

A platform team manages dozens of independent web applications and needs large-scale isolation across all of them, rather than deep OS-level customization for any single app. Based on App Service's decision guidance, which option should they choose?
