The SLA@SOI project has researched and engineered technologies to embed SLA-aware infrastructures into the service economy. It has published models, defined architectures, developed an open-source framework and driven open standards such as the Open Cloud Computing Interface. In this demo the application of SLA@SOI in an enterprise IT use case will be demonstrated. The presentation will cover t...

In order to reduce costs, many enterprises have started to focus on their core business processes. As a consequence non-central business processes more and more are outsourced to external service providers. The relelationships between service providers and the service consumers are laid down in legal contracts called Service Level Agreements (SLAs). It is the task of the Service Level Managemen...

BACKGROUND This study explored the effects of nano-hydroxyapatite/polyetheretherketone (n-HA/PEEK)- coated sandblasted, large-grit, and acid-etched (SLA) implants on inflammatory cytokines and osseointegration in peri-implantitis model beagle dogs. MATERIAL AND METHODS Peri-implantitis models were established. Eight beagle dogs were randomly and evenly assigned into SLA tied, SLA + n-HA/PEEK ti...

A Service Level Agreement (SLA) is an electronic contract between the consumer and the provider of a service. It governs their business relationship by clarifying expectations and obligations of participating entities, with regard to the service and its quality. SLAs are already the prime paradigm for the description of cloud computing services. Once an SLA is established, the provider has to e...

The paper proposes a structure for quality-of-service (QoS)-centered service level agreements (SLA), and a framework for their real-time management in multiservice packet networks. The SLA is structured to be fair to both parties, the service provider and their customer. The SLA considered here are for QoS assured delivery of aggregate bandwidth from ingress to egress nodes; however, the contro...

Selenocysteine (Sec) is inserted into selenoproteins co-translationally with the help of various cis- and trans-acting factors. The specific mechanisms of Sec biosynthesis and insertion into protein in eukaryotic cells, however, are not known. Two proteins, SECp43 and the soluble liver antigen (SLA), were previously reported to interact with tRNA([Ser]Sec), but their functions remained elusive....

With Grid computing adopting Service Oriented Architecture (SOA), resources are represented by services with standardized interfaces and the management of resources converges to the more general management of services (i.e. the Service Level Management). The key to Service Level Management is the management of Service Level Agreement (SLA), a formal contract between the provider and consumer of...

The negotiation on Service Level Agreement (SLA) in current complex cloud environment often involves the multilateral negotiation. Therefore, this paper presents an SLA-oriented multiparty trust negotiation model based on Hierarchical Colored Petri Net (HCPN) in cloud environment. This model mainly provides trust negotiation of SLA parameters such as credibility, reliability, availability and s...
