Question

Difficulty: MediumAzure Serverless Compute (Functions and Logic Apps)

An online hotel booking platform is building an automated guest feedback system. The solution has the following requirements:

1. A visual, designer-first orchestration engine to integrate customer reviews with external CRM software.
2. A custom-coded JavaScript function that runs on demand to parse feedback sentiment.

Which of the following Azure serverless services should the platform use to meet these requirements? (Select two)

  1. Azure Logic AppsAnswer
  2. Azure FunctionsAnswer
  3. C
    Azure Virtual Machines
  4. D
    Azure App Service

Answer

Azure Logic Apps and Azure Functions are the correct choices. Azure Logic Apps is used for designer-first workflow orchestration, and Azure Functions is used for custom, event-driven serverless code execution.
Azure Logic Apps is a designer-first serverless integration service that enables the visual design of workflows using built-in connectors to orchestrate tasks across applications. Azure Functions is a code-first serverless compute service that enables running custom code blocks (such as JavaScript) on demand in response to events without configuring servers.

Step-by-Step Solution

1
Analyze the first requirement: 'A visual, designer-first orchestration engine to integrate customer reviews with external CRM software.'
This requires Azure Logic Apps, which is designer-first and connector-driven.
Azure Logic Apps is designed for integrating services and SaaS applications using a visual editor without writing custom code.
2
Analyze the second requirement: 'A custom-coded JavaScript function that runs on demand to parse feedback sentiment.'
This requires Azure Functions, which is a code-first serverless platform.
Azure Functions allows developers to write custom code in languages like JavaScript that executes in response to events.
3
Evaluate the remaining options: Azure Virtual Machines and Azure App Service.
These do not fit the serverless requirements.
Azure Virtual Machines is an IaaS service requiring OS management, and Azure App Service is a PaaS app hosting platform using dedicated compute resources rather than event-driven consumption billing.
