Running workflows in the cloud often requires certain custom behaviors, so ZenML offers a number of extra Stack Components that handle these common use cases. For example, it's common to want to deploy models so we have a Model Deployer component. Similarly, you might want to use popular tools like Weights & Biases or MLflow to track your experiments, so we have an Experiment Tracker stack component. Any additional software needed for these components can be added and installed by using ZenML's Integration installer.
