An underlying cloud computing feature, outsourcing of resources, makes the service-level agreement (SLA) a critical factor for quality of service (QoS), and many researchers have addressed the question of how an SLA can be evaluated. Lately, security SLAs have also received much attention to guarantee security in a user perspective and provide optimal and efficient security service in the secur...

Service Level Agreements (SLAs) are a vital instrument in serviceoriented architectures to reserve service capacity at a defined service quality level. Provisioning systems enable service managers to automatically configure resources such as servers, storage, and routers based on a configuration specification. Hence, agreement provisioning is a vital step in managing the lifecycle of agreement-...

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...

A Service Level Agreement (SLA) contains one or more Service Level Objectives (SLOs) that describe the agreed upon quality requirements at the service-level. In order to manage the service to meet the agreed upon SLA, it is important not only to design a service of the required capacity but also to monitor the service thereafter for violations at runtime. This objective can be achieved by under...

Abstract This study aims to design and build an android-based trouble tictket application in order support the implementation of SLA (Serive Level Agreement). idea originated from increasing number internet users Indonesia, so that level competition among service provider companies is also increasing. condition makes consumers more selective choosing providers. Companies must improve their serv...

This paper provides an outline for generating Möbius reward constructs and a partial Stochastic Activity Network model from an existing Web Service Level Agreement (WSLA) document of a web service system. This is done by parsing the WSLA document to group its ‘Service Level Agreement parameter elements’ with their corresponding ‘metric elements’ using the Document Object Model parser. These gro...

With the number of e-Business applications dramatically increasing, a service level agreement (SLA) will play an important part in Web services. The SLA is a combination of several quality of services (QoS), such as security, performance, and availability, agreed between a customer and a service provider. Most existing research addresses only one of these QoS metrics. Furthermore, in the case o...

This paper presents a multi-domain Internet service management framework that uses Service Level Agreement (SLA) to support QoS and to exchange management information across domain boundaries. In rapidly growing Internet/Intranet environments, there is no standard mechanism to exchange management information between service providers and their customers or between several service providers. Suc...

In this paper, we derive stochastic performance bounds under the assumption of exponentially bounded burstiness (EBB) traffic model and exponentially bounded fluctuation (EBF) channel model. Then we propose a measurement-based call admission algorithm providing statistical service level agreement (SLA) guarantee for accepted flows based on the QoS prediction equations for both single and multip...
