Azure DevOps, now known as Azure DevOps Services, is a set of development tools and services provided by Microsoft to help teams plan, develop, test, deliver, and monitor software projects. It encompasses a wide range of functionalities, from version control to build automation, testing, release management, and more. Azure DevOps is commonly used by software development teams to streamline their development and delivery processes.

Here are some key components and features of Azure DevOps:

1. Azure Repos: This is a version control system that provides Git repositories for source code management. It allows teams to collaborate on code, track changes, and manage branches.

2. Azure Boards: A work tracking system that provides tools for project planning, managing work items (such as user stories, tasks, bugs), and tracking progress using Agile, Scrum, or custom methodologies.

3. Azure Pipelines: A continuous integration and continuous delivery (CI/CD) platform that automates building, testing, and deploying applications to various environments. It supports multiple programming languages, platforms, and cloud providers.

4. Azure Test Plans: This feature allows you to plan, track, and manage testing efforts for your software projects. You can create test cases, execute manual and automated tests, and generate test reports.

5. Azure Artifacts: A package management system for managing and sharing packages (such as NuGet, npm, Maven) across your development teams. It provides a central repository for storing and versioning packages.

6. Azure DevOps Services Dashboards: Customizable dashboards that provide visualizations of your team’s progress, work items, builds, and other key metrics.

7. Azure DevOps Extensions: You can enhance the functionality of Azure DevOps by installing extensions from the Azure DevOps Marketplace. These extensions can add new features, integrations, and automation capabilities.

8. Integration with Azure: Azure DevOps integrates seamlessly with Microsoft Azure, Microsoft’s cloud computing platform, to provide end-to-end application development, deployment, and monitoring solutions.

9. Security and Compliance: Azure DevOps offers security features like access control, authentication, and encryption to ensure the safety of your code and data. It also supports compliance with various industry standards.
