Management middleware for enterprise grids

Abstract

Management continues to be a problem for grids. A diversity of systems is in use. Their integration into more comprehensive management solutions that would simplify management, address the scale of grids and enable a higher degree of automation is difficult. This paper presents a management middleware that normalizes management for enterprise grids. Management tasks are rendered as autonomous services following a model-based approach. The paper first introduces the problem domain of managing enterprise grids and then describes the approach to a solution. The concept of a service delivery controller (SDC) is introduced that allows describing management tasks in terms of desired and observed state models, based on which a controller function autonomously performs tasks. The implementation of SDC inform of the SDC toolkit is discussed next. The SDC toolkit is based on the Globus Toolkit GT4. It extends GT4 by the standard for Web services distributed management (WSDM) and SDC-specific capabilities. Finally, a scenario is described where the developed approach and implementation have been applied to management of the Oracle 10g (grid) database system.
