Abstract: The invention relates to a computer system comprising a pattern composer (108) operatively coupled to a source IT-infrastructure (130) and to a tar­get IT-infrastructure (116, 118, 120). The source IT-infrastructure hosts a composite application (128) comprising multiple functional modules (C1-04) connected to each other via communication links. An abstract pattern com­prises first nodes and first links representing the functional module and communication links and lacks resource-related data enabling a deployment engine (110) to instantiate said resource for providing a runtime environ­ment for the functional modules and communication links. The target IT-infrastructures has assigned a resource catalogue (RC1-RC3) comprising, for each resource available in said target IT-infrastructure, a specification of said resource's capabilities, and comprises second nodes and links each second node being a representation of one or more of the resources of the target IT-infrastructure and comprising an indication the capabilities of said one or more resources represented by said second node. The pattern composer is configured for iteratively supplementing the first nodes and links of the abstract pattern by the second nodes and second links. There­by, the requirements of any supplemented first and second nodes and links are inherited to the supplementing nodes and links in each iteration.
