What is Azure DevOps used for?
Azure DevOps is a suite of development tools and services used for managing software development projects. It supports the entire software development lifecycle, including planning, coding, building, testing, deploying, and monitoring applications. Azure DevOps provides services such as version control, continuous integration and delivery (CI/CD), agile project management, and testing, enabling teams to collaborate efficiently and deliver high-quality software faster.
Is Azure DevOps similar to Jira?
While Azure DevOps and Jira have overlapping functionalities, they serve slightly different purposes. Both are used for project management and issue tracking, but Azure DevOps offers a broader set of tools for the entire DevOps lifecycle, including CI/CD pipelines and integrated development environments (IDEs). Jira is primarily focused on agile project management and issue tracking, making it a popular choice for teams using Scrum or Kanban methodologies.
Is Azure DevOps coding?
Azure DevOps itself is not coding, but it provides a platform and tools that facilitate the coding process. Developers use Azure DevOps to manage their code repositories, set up automated builds and releases, and collaborate on code through pull requests and code reviews. It supports various programming languages and integrates with popular IDEs to streamline the development workflow.
Which tool is used for Azure DevOps?
Azure DevOps encompasses a range of tools, including:
- Azure Repos: For source control management.

Which tool is mostly used in DevOps?
One of the most commonly used tools in DevOps is Jenkins, an open-source automation server widely adopted for continuous integration and delivery (CI/CD) pipelines. Jenkins is highly extensible and integrates with many other tools and services, making it a cornerstone in many DevOps toolchains.
What is the full form of DevOps?
The full form of DevOps is Development and Operations. It represents a set of practices that aim to unify software development (Dev) and IT operations (Ops) to improve collaboration and productivity by automating processes and continuously delivering high-quality software.
Is DevOps full of coding?
DevOps involves a significant amount of coding, especially in the context of automation and scripting. DevOps engineers often write scripts for automation, configuration management, and infrastructure as code (IaC). However, DevOps also encompasses other activities such as system administration, monitoring, and collaboration, which may not require extensive coding.
What is DevOps salary?
The salary for a DevOps professional can vary widely based on factors such as experience, location, and industry. As of recent data, the average salary for a DevOps engineer in the United States ranges from $90,000 to $140,000 per year. Senior-level positions and specialized roles can command even higher salaries. (Click here to read more about DevOps Profile and salary)

In Azure Repos, a pull request is a mechanism for proposing and reviewing changes to code stored in a Git repository. Here’s how it generally works:
- Initiating a Pull Request: When a developer wants to merge changes from one branch (typically a feature branch) into another branch (like main or development), they initiate a pull request. This signals to the team that they have completed work and are ready for feedback and integration.
- Review Process: Other team members or designated reviewers are notified of the pull request. They can then review the proposed changes, leave comments, suggest modifications, or approve the changes.
- Collaboration and Iteration: Pull requests facilitate collaboration and iterative improvement. Reviewers and the original author can discuss the changes directly within Azure Repos, ensuring that code quality, functionality, and adherence to coding standards are maintained.
- Integration: Once approved, the changes are merged into the target branch. Azure Repos keeps track of the history of these changes, allowing teams to understand when and why specific changes were introduced.
- Automated Builds and Tests: Azure Repos can be configured to trigger automated builds and tests when a pull request is created or updated. This helps ensure that proposed changes do not introduce errors into the codebase.
Overall, pull requests in Azure Repos enhance collaboration, maintain code quality, and facilitate effective code review processes within development teams.
Q25. How can you enforce code quality in Azure DevOps?
Ans:
