The services do not have to be licensed throughout the company, but can be reserved in addition for each user. The licensed customer is either the Standard Edition or the Enterprise Edition of each service. The duration of EDOS is three years and is linked to an EA. If a company has global administrators who sometimes manage several thousand licenses, a lot can fall through the grid. One solution is to appoint local, group, or department administrators to keep an eye on the licenses. This roll-based access control (RBAC) approach, which implements local operators, combines process and workflow automation with tight and careful license management, delivers deep cost savings and complete license optimization.
