WS-Agreement is a language and protocol designed for creating Service Level Agreements (SLAs) based on initial offers, and for monitoring those offers at runtime. The definition of WS-Agreement protocol is very general and does not contemplate the possibility of changing an agreement at runtime. This paper presents extensions of the WS-Agreement specification to support the dynamic nature of SLAs by allowing the possibility of SLA renegotiation at run time. The extended WS-Agreement specification have been implemented and tested. Within this implementation, the concept of renegotiation is demonstrated through the ability to create more than one SLA at runtime. An evaluation is conducted to examine the profits a service provider may gain through renegotiation, as well the savings resulting from rescuing the SLA from violations as a consequence of avoiding paying penalties. The results show that making the SLA terms adaptable and changeable is a viable mechanism that provides flexibility to the service provider and service consumer.

“…Pichot et al [17] propose and discuss extensions to the WS-Agreement protocol which support dynamic negotiation and creation of SLAs in an efficient and flexible manner. Some examples of WSAgreement implementations are WSAG4J [6,7], Cremona [18] and the SORMA project [19]. WSAG4J (WS-Agreement for Java) framework is a tool developed by Fraunhofer SCAI [6,7] to create and manage service level agreements (SLAs) in distributed systems.…”

“…the service provider and the service consumer. SORMA (Self-Organizing ICT Resource Management) [19] implement an Open Grid Market in a comprehensive way by addressing three arguments: the economic model providing an economically sound market structure; the self-organization model, which deals with the interaction between the Grid-application and the market and provides intelligent tools; and the economic middleware model, which builds the bridge between the self-organization and the economic model on the one side and state-of-the-art Grid infrastructure on the other side.…”

Abstract. The emerging transformation from a product oriented economy to a service oriented economy based on Cloud environments envisions new scenarios where actual QoS (Quality of Service) mechanisms need to be redesigned. In such scenarios new models to negotiate and manage Service Level Agreements (SLAs) are necessary. An SLA is a formal contract which defines acceptable service levels to be provided by the Service Provider to its customers in measurable terms. SLAs are an essential component in building Cloud systems where commitments and assurances are specified, implemented, monitored and possibly negotiable. This is meant to guarantee that consumers' service quality expectations can be achieved. In fact, the level of customer satisfaction is crucial in Cloud environments, making SLAs one of the most important and active research topics. This paper presents an SLA implementation for negotiation, monitoring and renegotiation of agreements for Cloud services based on the CMAC (Condition Monitoring on A Cloud) platform. CMAC offers condition monitoring services in cloud computing environments to detect events on assets as well as data storage services.

“…There are many current examples of mature economically enabled brokers, meta-schedulers and distributed architec- tures such as Nimrod/G [6], DRIVE and SORMA [21]. A range of economic protocols have been deployed in each of these systems, all offer different approaches to contracts, security and architecture.…”

Economic models have long been advocated as a means of efficient resource allocation, however they are often criticized due to a lack of performance and high overheads. The widespread adoption of utility computing models as seen in commercial Cloud providers has re-motivated the need for economic allocation mechanisms. The aim of this work is to address some of the performance limitations of existing economic allocation models, by reducing the failure/reallocation rate, increasing occupancy and thereby increasing the obtainable utilization of the system. This paper is a study of high performance resource utilization strategies that can be employed in Grid and Cloud systems. In particular we have implemented and quantified the results for strategies including overbooking, advanced reservation, justin-time bidding and using substitute providers for service delivery. These strategies are analyzed in a meta-scheduling context using synthetic workloads derived from a production Grid trace to quantify the performance benefits obtained.
