Modelling dependencies of IT Infrastructure elements

Abstract

The management of IT-infrastructures has gained increased relevance to business as business processes and thus the business profit rely on IT services, which in turn depend on the underlying infrastructure. Even one single distributed IT service already depends on the correct interaction of many distributed IT resources within the IT infrastructure. The term service infrastructure in this context denotes the IT infrastructure resources which are involved within a service and are thereby in a relationship among each other. The changing states of resources and resource dependencies manifest the behaviour of the infrastructure and is correlated with the behaviour of a service facing the user and thus with the service quality. Thereby resource dependencies are of interest in the context of BDIM.
