Which of the following Azure services is designed for continuous integration and delivery?

The correct choice highlights Azure DevOps, which is a comprehensive suite of development tools and services specifically designed to support continuous integration and continuous delivery (CI/CD). Azure DevOps provides a range of features including build pipelines, release pipelines, and version control. These tools allow development teams to automate the process of integrating code changes frequently, thereby enabling faster and more reliable software delivery.

Azure DevOps is tailored to meet the needs of modern development practices by integrating with numerous programming languages and tools, facilitating collaboration across teams, and ensuring that applications can be deployed effectively in various environments. It truly embodies the principles of Agile and DevOps methodologies, making it essential for teams aiming to implement CI/CD workflows efficiently.

Other options listed do not serve this same function: Azure Functions is a serverless compute service that allows you to run code without managing servers. Azure App Service is a platform for building and hosting web applications but does not directly provide CI/CD capabilities. Azure Blob Storage is designed for storing unstructured data and does not relate to software integration or delivery processes. Therefore, Azure DevOps stands out as the right choice for continuous integration and delivery in the Azure ecosystem.
