SLA-driven management of distributed systems using the common information model

This paper gives a first insight in an ongoing investigation. Our generic aim is to describe the current situation of available Web Services in context with their quality of service (short QoS) behavior. The current quality behavior of offered Web Services should be evaluated in particular as an important aspect of an effective Service Level Management. After providing an introduction to Web Service technology, this contribution primarily aims to describe the topic of service level agreements (short SLA) management in such environments. In this context, we will highlight the general contents of SLA agreements, describe the interaction chain for service provision that arises in Webservice-based solutions, and provide a brief explanation of the opportunities offered by the WSLA framework that IBM has developed especially for Web Services. Finally we describe the conception, prototypical development and the possible application of a measurement service for monitoring the quality behavior of an specific Web Service. This measurement service can be used to support service level agreements.

“…Realizing Service Level Agreement in a distributed system has been studied in [5,6,7]. In SNAP [6], a multi-phase SLA is presented to manage distributed resources for complex tasks which consist of a variety of sub-jobs requiring various distributed resources. In [7], an SLA-driven distributed resource management platform is proposed to integrate WSLA and Common Information Model for distributed resource management.…”

“…Most of the existing work considers resource allocation by advance reservation. Our work is different from [6,7] in that we consider managing QoS by real-time monitoring QoS and adapting the resource allocation when violation happens. We propose that QoS management is an inter-layer between the SLA negotiation and the resource management so as to support QoS-aware services with the capabilities of QoS negotiation, monitoring, resource allocation and QoS adaptation.…”

In this paper, we present an SLA-driven QoS Management Platform which establishes service level agreement between the service provider and the customers before the service delivery and manages the distributed resources efficiently to support QoS-aware multimedia personalized services (MPS) over large scale networks. Based on service oriented architecture, such a QoS management platform consists of SLA negotiation, QoS management and resource management. The QoS management connects the SLA negotiation and resource management to real-time monitor QoS and adapt the quality levels to cope with the varying network conditions. Such a QoS management platform allows clients to specify the QoS requirements, and enables service providers to offer different QoS levels, negotiate with their customers on the possible quality levels and adapt the resources allocation to optimize the system overall performance. We constructed a prototype system and study the QoS management in both static and dynamic service modes. Experiments are conducted to examine the system communication overhead caused by the SLA communication, and system performance by integrating various strategies for QoS management. The results show that our proposed SLAdriven QoS management platform is highly flexible, extensible and efficient to support QoS-aware MPS over large scale networks.

“…Action guarantees are used as a means to meet SLOs. [ 10] adds on this work by proposing an approach of using CIM for the SLA-driven management of distributed systems. It proposes a mapping of SLAs, defined using the WSLA framework, onto the CIM information model.…”

In this paper, we introduce a business aware framework for the policy-based management of IT Systems and its application to utility computing environments. The framework couples two main subsystems on top of an IETF-like policy-based resource control layer. They are MBO (Management by Business Objectives) where the decision ability supported by analysis of business objectives resides, and GSLA (Generalized SLA), an advanced framework for SLA driven management that lends itself quite naturally to the derivation of IT management policies from the SLAs that the enterprise has contracted. We discuss the advantages and the limitations of the stateof-art policy-based approach to systems management, mainly the lack of business and service level context to drive policy-related decisions at system runtime. We then explain how this is remedied in our framework through the interaction mechanism between the reactive policy-based resource control layer and the more proactive business driven decision making engine.
