Abstract

Embodiments provide techniques for customers to easily, quickly and remotely manage their virtual data centers. Using, for example, a “single pane of glass” GUI view which shows all of the components (including e.g., machines (cpu and RAM), network services (load balancers, firewalls, network address translation, IP management) and storage) of their virtual data centers, provides a complete overview and a starting point for system or component management. According to embodiments, a Roles Based Access Control (RBAC) system is provided which simulates the organizational structure and workflow of a typical IT department to enable workflow management via the GUI for any component or function of a customer'"'"'s virtual data center.
