CI/CD is a method that helps application development teams to provide code changes to users more frequently and reliably. CI/CD introduces automation into the stages of code deployment.
When several developers collaborate and contribute to the same application (each of them responsible for a certain microservice or fixing a specific bug), they use a code version control provider to aggregate the application using the latest code versions that the developers have uploaded and pushed.
