Adaptive Services Grid Deliverable D 5 . II - 7 Design and Integration of SLA Monitoring and Negotiation Capabilities

for dissemination Adaptive Services Grid (ASG) is an Integrated Project supported by the Sixth Framework Programme of the European Commission under the Information Society Technology Objective Open Development Platforms for Software and Services. The goal of ASG is to develop a proof-of-concept prototype of an open platform for adaptive services discovery, creation, composition, and enactment. This deliverable underlines the efforts of supporting the development of the above mentioned platform to realize the ASG Service Provisioning Features, especially the reliable service provision with assured quality of service. Providing an assured level of quality demands the ability to measure quality-relevant attributes, i. e. monitoring, and the ability to negotiate quality-of-service parameters. While negotiation is researched by other work components, validation of conformance between a service-level agreement (SLA) and the effectively delivered service with regard to QoS aspects demands application or service management and monitoring at infrastructure level. In the context of the ASG platform, higher layers therefore need monitoring support at the level of the execution environment and in particular throughout the whole implementation of the C-5 Services Infrastructure (SI). Our document discusses first the business-related requirements of application management and monitoring, and presents then an appropriate monitoring model and its implementation in our reference implementation We further discuss the relation of ASG SLA negotiation capabilities to the presented monitoring functionalities, and show how the results of other work components in ASG working on this SLA negotiation are integrated in our framework.
