Evaluation of an Accounting Model for Dynamic Virtual Organizations
Accounting of Grid resource and service usage
determines the central support activity for Grid systems to
be adopted as a means for service-oriented computing in Dynamic Virtual Organizations (DVO). An all-embracing study of existing Grid accounting systems has revealed that these
approaches focus primarily on technical precision, while
they lack a foundation of appropriate economic accounting principles and the support for multi-provider scenarios
or virtualization concepts. Consequently, a new, flexible, resource-based accounting model for DVOs was developed,
combining technical and economic accounting by means of
Activity-based Costing (ABC).
Driven by a functional evaluation, this paper pursues a
full-fledged evaluation of the new, generically applicable
Grid accounting model. This is done for the specific environment of the Leibniz Supercomputing Centre (LRZ) in
Garching, Germany. Thus, a detailed evaluation methodology and evaluation environment is outlined, leading to
ology and evaluation environment is outlined, leading to
considered Grid services. The results gained are analyzed
and respective conclusions on model applicability, optimizations, and further extensions are drawn.
