Abstract. Maintaining trust in cloud computing is a significant challenge due to the dynamic nature of cloud computing and the fragility of trust. Trust can be established by conducting successful transactions and meeting all the parameters of the Service Level Agreement (SLA) drawn up between two interacting parties. Trust can be maintained by continuous monitoring of these predefined SLA parameters. There are number of commentaries on SLA monitoring that describe different frameworks for the proactive or reactive detection of SLA violations. The aim of this research is to present an overview of the literature and make a comparative analysis of SLA monitoring in respect of trust maintenance in cloud computing.

“…Regardless of the actual status of the service, that consumer may want to manipulate monitoring results to make it appear unreachable and therefore collect financial compensation. To prevent this situation from occurring, a Trusted Third Party (TTP) is used to perform monitoring measurements [16,15]. A TTP is an independent party that can access all communication between the parties to the SLA.…”

“…Active monitoring performs specific measurements at specified intervals. Active monitoring is used to monitor SLAs [14,15]. A service is monitored by periodically testing whether the terms of an SLA have been met by all parties.…”

Abstract. This paper presents an Intelligent Cloud Resource Allocation Service (ICRAS) that assists consumers with the complex task of finding the optimal configuration of Cloud resources given a consumer's specific needs. The process of selecting a CSP becomes increasingly complex as the number of Cloud Service Providers (CSP) offering similar services continues to grow. Consumers can pick and choose between CSPs based on a growing number of options, including price, Quality of Service, reputation and so forth. The advent of dynamic pricing (based on real-time availability) further increases the complexity of CSP selection. ICRAS alleviates much of this burden from the consumer by automating the processes of service discovery, evaluation, negotiation and migration. Furthermore, ICRAS monitors Service Level Agreement (SLA) compliance using non-repudiable monitoring techniques.

Over the years the Internet became the primary means of communication, many companies use it as basis for their services. However, the current Internet does not guarantee Quality of Service, emerging the concept of network virtualization as the basis for the Future Internet. A common strategy used by companies is to define a Service Level Agreement (SLA) with their respective Internet Service Providers. Within this context, this paper proposes a full automatic SLA negotiation protocol for a Future Internet. The proposed protocol allows the client to negotiate network resources and the protocol stack used in the virtual network.
