Governance of Enterprise Systems

Enterprise systems are large-scale application landscapes consisting of hundreds of heterogeneous software systems. They are custom-tailored to support the specific and mission-critical business processes of a company. At the same time, they have to fulfill conflicting demands: while minimizing costs, IT solutions have to support a wide range of functionality, be highly reliable and flexible. To that end, several paradigms have been introduced over time such as Service-oriented Architectures (SOA) and Cloud Computing.

The work at DVS aims at supporting a company's IT Service Management (ITSM) in managing runtime aspects of those enterprise software systems by providing them with appropriate models and abstractions.
