How does Git Work?

The diagram below shows the Git workflow.

Git is a distributed version control system. Every developer maintains a local copy of the main repository and edits and commits to the local copy. The commit is very fast because the operation doesn’t interact with the remote repository. If the remote repository crashes, the files can be recovered from the local repositories.

.
Redis can be used in a variety of scenarios as shown in the diagram.
