Azure DevOps Interview Questions and Answers

Microsoft’s Azure DevOps is a Software as a Service platform. It is a hosted service providing development and collaboration tool that was formerly known as Visual Studio Team Services (VSTS). It is one of the tools that has multiple services and you can use the services to create DevOps life cycle in their process.

Following are the Azure DevOps Components:

Azure Pipelines: These Pipelines are the CI/CD tool that facilitates automated building, testing, and deployment

Azure Boards: It will help you to quickly plan, manage, and track work and in custom reporting across your entire team.

Azure Artifacts: It is used to create, store, and share packages (development artifacts). This component ensures your pipeline has fully integrated package management.

Azure Repos: It Provides full-support for cloud-hosted private repositories.

Azure Test Plans: A solution for tests and capturing data about defects. Its includes manual/exploratory testing and continuous testing.

Following are the key DevOps Components:

• Continuous development
• Continuous integration
• Continuous testing
• Continuous deployment
• Continuous monitoring
• Continuous feedback
• Continuous operations

Azure Test Plans supports the following test objectives:

• Manual and exploratory Testing: Planned manual testing, User acceptance testing, Exploratory testing, Stakeholder feedback.
• Automated Testing
• Traceability
• Reporting and analysis

Key concepts for new Azure Pipelines users:

A trigger initiates an Azure DevOps Pipeline to run.

A pipeline can have many stages. A pipeline can deploy to single or multiple environments.

A stage can be specified to manage jobs in a pipeline and each stage has various jobs.

Each job runs on one agent. It’s also possible that a job doesn’t have an agent.

Each agent runs a job that may have various steps.

A step can be anything like a script or task and it is the compact part of a pipeline.

A task is a pre-bundled script that acts like to publish a build artifact or to call a REST API.

A run publishes a bunch of files or bundles called an artifact.

There are several tools used to test the Azure DevOps pipeline locally. These tools include Visual Studio Code extension Azure Pipelines, and Azure DevOps Snippets. They can help in showcasing the YAML flow hierarchy, Azure DevOps pipeline parameters, and tasks.

Key benefits of Azure Test Plans:

• Test on any platform
• Integrated Analytics
• Rich diagnostic data collection
• End to End Traceability
• Extensible Platform

The Azure DevOps Server, previously known as the Team Foundation Server (TFS), is a DevOps server solution that is targeted for on-premise deployments. Azure DevOps Server is built on the SQL Server backend. Usually, customers choose this product when they think their data should reside within their network and also if they need access to SQL Server Reporting Services.

Get Started Fast and Robust – In the Azure account, there are IoT Services on Azure ready to use without the need to set up or software to install.

Programmable: – It also provides an option to each service via the Azure CLI or through API’s

Automation: – Azure uses automation to build faster and more efficiently.

Fully Managed Services – These services take advantages of Azure resources without worrying about settings of installing software or operating infrastructure on our own.

Built for Scale: – It manages a single instance and also scales up to thousands using Azure services.

Secure and Safe: – Azure IAM sets user permission and policies. It is used for user access on particular services of Azure resources and how user access those services.
