H2O Admin Center is an application that allows users to control the environment on which the application is running. Fundamentally, H2O Admin Center enables users to customize a unique string of characters that identifies each computer using the Internet Protocol to communicate over a network and web addresses on the HADC (H2O AI dedicated cloud) environment. The application allows User groups and Admin groups to run the application so they could have sole control.
