dbt Cloud deployment starts by writing SQL models. These models are saved as files. Next, you commit these changes locally using Git, then push them to a remote repository. dbt Cloud accesses this remote repo to get the latest code. You then trigger a dbt Cloud job manually or by schedule. The job runs your models by compiling and executing SQL in your data warehouse. After the run, you check the job logs for success or errors. If successful, your models are deployed and updated in the warehouse. If errors occur, you fix them and rerun the job. This process ensures your data models are version controlled and deployed safely.
