Google Cloud Console offers a web-based, graphical user interface that helps you to manage your Google Cloud projects and resources. When you use the Cloud Console, you can create a new project, or select an existing project, and use the resources that you create for that project. You can create also multiple projects that allow you to use projects to separate your work.
