The process of initially setting up or later updating a live website. There are lots of components (server configuration, code, database, files, permissions) and steps involved so that such a deployment task can take a while and needs to be executed very carefully to make sure it doesn't break anything. can be done manually - which is not recommended - or automatically. With automation it is very easy to also include additional tasks like testing and pre-processing into the task and the expected result is always going to be the same. Nothing gets missing and it will only always happen, if all conditions (tests, coding standards, etc.) are met.

Where all of Drupal core  up to Drupal 7 had been exposed in the main project folder, all the contributed code from the Drupal community and third parties was located deep down in the code tree with custom code for the specific project sometimes was hard to separate from other contributions.
