Issues with traditional deployment

No versioning is provided in a sandbox environment, so it becomes difficult when multiple developers are working on a project and are not in sync. Keeping track of all changes in project can look like finding a needle in a haystack. Deployment with a change set is not recommended for large projects and creating a change set is not scriptable. So it becomes a repetitive task.

The Force.com Migration Tool is good for large projects, but we do not have versioning, so we cannot revert code to its previous version. Also, we are not able to track changes done by developers. 

We have different environments, such as development, test, stage, and production, in almost all technical stacks. In Salesforce, we use a sandbox for development and test environments. Sandboxes come in different types as per our requirement, and we can choose which sandbox to use. Let's look at the different types of sandboxes.
