Understanding SCM

Source control (or version control) is a software practice used to track and manage changes in source code. This is an extremely important practice because it permits to maintain a single source of code across different developers and helps with collaborating on a single software project (where different developers works on the same code base).

SCM is an essential practice in any DevOps process. To adopt a source control policy, you should do the following:

• Select a source control management system to adopt (for example, install Git on a server or use a cloud-based SCM such as Azure DevOps Repos or GitHub)
• Store your code base in a repository managed by your source control management system
• Clone the repository locally for development by taking the latest code version (pull) stored in the central repository
• Commit and push your released code to the central repository
• Use different copies of the repository for developing in a parallel way...
