Difficulty: MediumAzure Container Instances, Azure Kubernetes Service, and Azure App Service

A company plans to migrate a custom web API to Azure. The development team wants to deploy the application code directly without packaging it into container images or managing the underlying web server software. Additionally, the team requires that Microsoft automatically handles operating system updates and security patches.

Which Azure service should the company select to meet these requirements?

  1. A
    Azure Virtual Machines
  2. B
    Azure Kubernetes Service (AKS)
  3. Azure App ServiceAnswer
  4. D
    Microsoft 365

Answer

Azure App Service
Azure App Service is a Platform as a Service (PaaS) offering designed to host web applications, REST APIs, and mobile backends. In a PaaS model, Microsoft manages the hardware, operating system, and web server software, including all updates and security patching. Developers can deploy their application code directly to the service without having to containerize it first.

Step-by-Step Solution

1
Identify the deployment format and infrastructure management constraints from the scenario.
The application code must be deployed directly without containerization, and the operating system must be patched automatically by Microsoft.
This establishes the requirements needed to distinguish between IaaS, PaaS, and container hosting options.
2
Evaluate the capabilities of each option against the constraints.
Azure Virtual Machines requires manual OS management. Azure Kubernetes Service requires containerization. Microsoft 365 is a SaaS product and cannot host custom APIs. Azure App Service is a PaaS solution that supports direct code deployment and automates OS updates.
Matching the requirements to the correct service model determines the appropriate target service.

Key Concept

Distinguishing the management responsibilities and deployment constraints of Azure App Service from Infrastructure as a Service (IaaS) and container-based offerings.
