Dynamic Placement of Virtual Machines for Managing SLA Violations

2007 10th IFIP/IEEE International Symposium on Integrated Network Management, 2007
A dynamic server migration and consolidation algorithm is introduced. The algorithm is shown to provide substantial improvement over static server consolidation in reducing the amount of required capacity and the rate of service level agreement violations.

Trustworthy Detection and Arbitration of SLA Violations in the Cloud

2018
In cloud computing, detecting violations of Service Level Agreements (SLAs) is possible by measuring certain metrics, which can be done by both the provider and the consumer of a service. However, both parties have contradicting interests with regards to these measurements, which makes it difficult to reach consensus about whether SLA violations have ...

Monitoring, Prediction and Prevention of SLA Violations in Composite Services

2010 IEEE International Conference on Web Services, 2010
We propose the PREvent framework, which is a system that integrates event-based monitoring, prediction of SLA violations using machine learning techniques, and automated runtime prevention of those violations by triggering adaptation actions in service compositions.

Server Consolidation with Minimal SLA Violations

2015
Cloud computing is very promising technology to deliver computing resources like infrastructure (IaaS), platform (PaaS), software (SaaS) etc. in form of services over the Internet. Server consolidation is the mechanism to minimize active (running) physical servers in the data center of cloud service provider. Consolidation helps the service provider to

Proactive Learning from SLA Violation in Cloud Service based Application

Proceedings of the 6th International Conference on Cloud Computing and Services Science, 2016
In recent years, business process management and Service-based applications have been an active area of research from both the academic and industrial communities. The emergence of revolutionary ICT technologies such as Internet-of-Things (IoT) and cloud computing has led to a paradigm shift that opens new opportunities for consumers, businesses ...

On the Use of Traffic Information to Improve the Coordinated P2P Detection of SLA Violations

2014 IEEE 28th International Conference on Advanced Information Networking and Applications, 2014
Critical networked services are usually regulated by Service Level Agreements (SLAs). In order to ensure SLAs are being met, it is necessary to monitor Service Level Objectives (SLOs). Active measurement mechanisms are usually chosen to perform this monitoring task, which requires measurement probes to be activated in network devices.

Coordination in P2P management overlays to improve decentralized detection of SLA violations

2013 IEEE International Conference on Communications (ICC), 2013
Critical networked services enable significant revenue for network operators and, in turn, are regulated by Service Level Agreements (SLAs). In order to ensure SLAs are being met, service levels need to be monitored. One technique for this involves active measurement mechanisms which employ measurement probes along the network to inject synthetic ...

Manifold learning in SLA violation detection and prediction for cloud-based system

Proceedings of the Second International Conference on Internet of things, Data and Cloud Computing, 2017
SLA is a contract between service providers and consumers, mandating specific numerical target values which the service needs to achieve. For service providers, detecting and preventing SLA violation becomes very important to enhance customer trust and avoid penalty charges.

Handling SLA Violations via Constraint Imperative Programming

2013
The handling of violations of Service Level Agreement (SLA) is important for trustful service, particularly for web services in business field. In this paper, a SLA specification combines syntactic constructs from WS-Agreement and WSLA is proposed.

Detection of Service Level Agreement (SLA) Violations in Memory Management in Virtual Machines

2015 24th International Conference on Computer Communication and Networks (ICCCN), 2015
In cloud computing, quality of services is often enforced through Service Level Agreement (SLA) between end users and cloud providers. While SLAs on hardware resources such as CPU cycles or bandwidth can be monitored by low layer sensors, the enforcement of security SLAs stays a very challenging problem.
