The specialty of desktop-as-a-service cloud computing is that user can access their desktop and can execute applications in virtual desktops on remote servers. Resource management and resource utilization are most significant in the area of desktop-as-a-service, cloud computing; however, handling a large amount of clients in the most efficient manner poses important challenges. Especially decid...

Many organizations implement information technology (IT) service management practices to improve IT operations as it contributes to organizational performance. When outsourcing an IT service such as help desk support for customers, the organization may some of its ability to manage the relationship and ensure effective services are provided to the organization and customers. This paper presents...

This work deals with the main issues related to monitoring in the framework of the CADENUS project. Having defined an architecture capable to support dynamic service creation, configuration and delivery on top of Premium IP networks, the need arises to keep track of a number of parameters related to the quality of the service that has been negotiated and for which a formal contract (i.e. Servic...

A key aspect of Information Technology Service Management (ITSM) is the monitoring and evaluation of service performance – a task that is complicated by the presence of interrelationships among different service processes in a multiservice contract. While success in the service arrangement requires participant organizations’ knowledge about the nature of service dependency and their subsequent ...

Cloud consumers (CC) are confounded while taking the choice of selecting Cloud service provider (CSP) to accomplish Cloud services. Large number of CSPs are present in the market, which provide diverse cloud administrations viz Platform-as-a-Service PaaS, Infrastructure-as-a-Service IaaS and Software-as-a-Service SaaS. CSPs are conveying their Cloud services to CC in light of Service Level Agre...

We consider an SLA (Service Level Agreement) committed between two parties to use the guarantee of QoS provided by a QoS Enabled Network (QEN). QEN can provide guarantee of QoS because a Bandwidth Broker (BB) manages its resources based on a policy. The IETF and the DMTF have done extensive work in this field and have proposed a policy framework in order to store and manage policy and the stand...

In this paper we propose a new infrastructure for efficient job scheduling on the Grid using multi-agent systems and a Service Level Agreement (SLA) negotiation protocol based on the Contract Net Protocol. The agent-based Grid scheduling system involves user agents, local scheduler agents, and super scheduler agents. User agents submit jobs to Grid compute resources. Local scheduler agents sche...

When a network slice is requested, multiple technology and/or administrative domains are invoked to ensure that the end-to-end service level agreement (SLA) met. Therefore, this SLA requirement needs be decomposed in portions each of can support. In letter we consider management architecture consisting an orchestrator responsible for decomposing SLA, and domain controllers govern their respecti...

In this paper we present the requirements of a national computing Grid. In particular we discuss the issues involved in managing complex policies of multiple stakeholders in such a large-scale, dynamic, and heterogeneous Grid. We also propose a Service Level Agreement (SLA) and agent-based architecture to address these issues. This work is a continuation of the work performed and experiences ga...

Service Level Agreements (SLA) are needed to allow business interactions to rely on Internet services. Service Level Objectives (SLO) specify the committed performance level of a service. Thus, SLA compliance auditing aims at verifying these commitments. Since SLOs for various application services and end-to-end performance definitions vary largely, automated auditing of SLA compliances poses t...
