Workers can be automatically launched for you in Gretel Cloud. This is the default mode when uploading a configuration from the Console or the CLI. In cloud mode, once a request for a model is received, Gretel will provision a worker for you and the model and associated artifacts (such as quality reports, sample data, etc) will also be stored in Gretel Cloud. You may download these artifacts at any time. With a model created and stored in Gretel Cloud, model servers can be created to utilize the model and generate, transform, or classify data.
