The object of our investigation is a software architecture for adaptive Service Level Agreement (SLA) management in value chains for service individualization. We address the problem that current SLA management is not capable to represent the full complexity of SLAs existing in real-world service industries. The problem is investigated from a functional-analytical supply chain perspective. The ...

It is imperative for a competitive e-business outsourcing service provider to manage the execution of its service level agreement (SLA) contracts in business terms (e.g., minimizing financial penalties for service-level violations, maximizing service-level measurement based customer satisfaction metrics, etc.). In order to do that, the provider must possess a generic means of capturing and mana...

In recent years, extensive research has been conducted in the area of Service Level Agreement (SLA) for utility computing systems. An SLA is a formal contract used to guarantee that consumers‟ service quality expectation can be achieved. In utility computing systems, the level of customer satisfaction is crucial, making SLAs significantly important in these environments. Fundamental aspect is t...

Service Level Agreement (SLA) is a formal negotiated agreement between a service provider and a customer. The service level management (SLM) is the integrated management of all functionalities in the SLA life cycle. When a customer orders a service from a service provider, an SLA is negotiated and then a contract is made. In the SLA contract, QoS parameters that specify the quality level of ser...

We present a generic Service Level Agreement (SLA)-driven service provisioning architecture, which enables dynamic and flexible bandwidth reservation schemes on a per-user or a per-application basis. Various session level SLA negotiation schemes involving bandwidth allocation, service start time and service duration parameters are introduced and analysed. The results show that these negotiation...

A Service Level Agreement (SLA) is an electronic contract between a service user and a provider, and specifies the service to be provided, Quality of Service (QoS) properties that must be maintained by a provider during service provision (generally defined as a set of Service Level Objectives (SLOs)), and a set of penalty clauses specifying what happens when service providers fail to deliver th...

Cloud resources are majorly delivered to the customers in terms of services and the security here is implemented through the infrastructure security metrics via a Service Level Agreement (SLA). SLA is a legal framework betw...

Composite cloud services based on the methodologies of Software as a Service and Service-Oriented Architecture are transforming how people develop and use software. Cloud service providers are confronting the service selection problem when composing composite cloud services. This paper deals with an important type of service selection problem, minimizing the total cost of providing a composite ...

In utility computing, customer requests varying services from software to infrastructure as and when needed. As a result, there are many mobile cloud providers provide this services on demand basis as per current market needs.
