Microsoft Azure Architect Design (AZ-304) Practice Test

Is creating an Azure WebJob to run a legacy image processing application every hour a suitable solution?

1. Yes

2. No

3. It depends on resource availability

4. Only if it runs on Linux

The correct answer is: No

Creating an Azure WebJob for a legacy image processing application that needs to run every hour might not be a suitable solution due to several considerations related to the nature of WebJobs and the specifics of running legacy applications in Azure. Azure WebJobs are designed for lightweight, continuous or triggered background task execution that works well with Azure App Services. However, when dealing with a legacy image processing application, there are potential challenges, particularly if the application has specific dependencies or requires a particular environment that is not compatible with the WebJob framework. Additionally, legacy applications might not be optimized for the Azure environment, possibly leading to performance issues or complicating integration with Azure services. Factors such as the need for specific runtime versions, external libraries, or specialized resources might make running such an application in a WebJob impractical. Moreover, if the application requires substantial computational resources or specialized infrastructure, a more robust solution, like using Azure Functions, Azure Batch, or even running it in a Virtual Machine (VM), might be necessary. In summary, while Azure WebJobs are convenient for many use cases, their suitability for running a legacy application every hour depends heavily on the application's requirements and Azure's environment, often making it less than ideal.
