Enhancing a National Academic Computing Infrastructure with e-Contracting Capabilities
No full textClosing ranks between industrial and academic distributed systems R&D
has been and is on the agenda of many projects and initiatives. But although state-ofthe-art service-oriented architectures and infrastructures are developed and deployed
by both industry and academia, the services required and the service quality expected
and provided differ significantly. Opening its mostly academically used Grid
infrastructure to industry is an important objective of the D-Grid initiative. The
SLA4D-Grid project is contributing to that goal by engineering a Service Level
Agreement management layer on top of the existing infrastructure, providing eContracting capabilities to a large variety of industrial and academic customers. This
layer will allow service providers and consumers to reliably and dependably build
their business models upon it. This paper describes the aims of the SLA4D-Grid
project, summarizes its developments, and shows how business use cases can benefit
from an academic infrastructure enhanced with e-Contracting capabilities
Towards Autonomous Brokered SLA Negotiation
No full textToday the whole contract lifecycle in eBusiness is handled manually. Contracts are not only written and agreed upon by humans, they have to be manually translated into technical terms to become an electronic contract. More and more research activities in eBusiness focus on the usage of electronic contracts (in particular Service Level Agreements) and how they can be created and enforced autonomously. So far, proposed solutions were not taken up by business users because of low flexibility, poor usability and high maintenance costs. This paper presents a proposal how “traditional” approaches can be extended to a broker-based solution valuable to business users, in particular small and medium-sized enterprises. The focus is on one of the main phases in the SLA-lifecycle – the negotiation phase. The paper describes how SLA negotiation can be outsourced to third parties and what the benefits and difficulties of such an approach would be
Implementing an SLA Negotiation Framework
No full textDespite promising high value for electronic business, Service Level
Agreements have not yet found major uptake in the business world. A major obstacle
to adoption is the lack of adequate tools that facilitate and automate SLA
establishment on both the consumer as well as the provider side. In this paper, we
describe a generic framework for negotiating SLAs that has been designed and
implemented by the authors. The components automate large parts of the negotiation
process while at the same time letting the user retain control. An application scenario
has been realised using our framework showing that the negotiation and
establishment of SLAs is a viable solution for electronic contracting and that our
framework can facilitate this task
