Cloud SDK provides language-specific Cloud Client Libraries supporting each language’s natural conventions and styles. This makes it easier for you to interact with Google Cloud APIs in your language of choice. Client libraries also handle authentication, reduce the amount of necessary boilerplate code, and provide helper functions for pagination of large datasets and asynchronous handling of long-running operations.

The gcloud CLI manages authentication, local configuration, developer workflow, and general interactions with Google Cloud resources. With the Google Cloud CLI, it’s easy to perform many common cloud tasks like creating a Compute Engine VM instance, managing a Google Kubernetes Engine cluster, and deploying an App Engine application, either from the command line or in scripts and other automations.
