Besides, the rapid adoption of eBusiness has resulted in an ever-increasing set of complex applications and IT infrastructure components to be managed. Thus, in this paper, we address the substances specific for the complex service management and identify some possible problem areas arising from contractual agreements between involved parties as well as from the directions of where service management is heading nowadays. Initially we examine what may be perceived as heterogeneous and agile eBusiness. We perform an aspect-based analysis of researched scientific literature: a detailed assessment of various definitions, requirements and other facets specific to the dynamic nature of service management in heterogeneous e-Business environment. Furthermore, we evaluate business-driven against conventional approaches to design SLAs; finally we examine various service management models giving priority to on SOA architecture.
