Nowadays, the demand for online storage is increasing. Customers store their data and can retrieve them anytime and from anywhere without having to care about back up and data recovery. SLAs between Cloud providers and customers determine the level of service guaranteed by the former. A customer can be anyone from an individual person to enterprises. Customers have different needs and preferences. Our proposed system permits the creation and enforcement of customized SLAs, where customers choose the requirements that they need fulfilled. The proposed SLAs are associated with content terms pertaining to the nature of the content of the data stored. SLA enforcement is based on rules that are updated in runtime in order to proactively detect possible SLA violations and handle them in an appropriate manner.

“…We divide the related work into two categories (i) monitoring strategies [3]- [6], [13], [17], [31], [32], and (ii) SLA management including violation detection [7], [14], [15], [20], [22], [25]. In the analysis of the existing work in this area, we consider also Grid and service-oriented based systems, since they are related areas to Cloud computing.…”

“…Although a large body of work considers the development of reliable Cloud management infrastructures [7], [22], [25], there is still a lack of efficient application monitoring infrastructures capable to adequately monitor and detect SLA violations of different customer applications. Besides application monitoring, determination of the effective monitoring interval for applications executing on the same host is still an open research challenge.…”

Abstract-Cloud resources and services are offered based on Service Level Agreements (SLAs) that state usage terms and penalties in case of violations. Although, there is a large body of work in the area of SLA provisioning and monitoring at infrastructure and platform layers, SLAs are usually assumed to be guaranteed at the application layer. However, application monitoring is a challenging task due to monitored metrics of the platform or infrastructure layer that cannot be easily mapped to the required metrics at the application layer. Sophisticated SLA monitoring among those layers to avoid costly SLA penalties and maximize the provider profit is still an open research challenge. This paper proposes an application monitoring architecture named CASViD, which stands for Cloud Application SLA Violation Detection architecture. CASViD architecture monitors and detects SLA violations at the application layer, and includes tools for resource allocation, scheduling, and deployment. Different from most of the existing monitoring architectures, CASViD focuses on application level monitoring, which is relevant when multiple customers share the same resources in a Cloud environment. We evaluate our architecture in a real Cloud testbed using applications that exhibit heterogeneous behaviors in order to investigate the effective measurement intervals for efficient monitoring of different application types. The achieved results show that our architecture, with low intrusion level, is able to monitor, detect SLA violations, and suggest effective measurement intervals for various workloads.

“…Unfortunately, these lifecycles are only loosely coupled, which leads to a large variety of possible scenarios as shown in Figure 2. SERSCIS builds on the SLA definition and lifecycle developed under the NextGRID project [9] as implemented in the GRIA middleware [10], [11].…”

Abstract-The SERSCIS project aims to support the use of interconnected systems of services in Critical Infrastructure (CI) applications. The problem of system interconnectedness is aptly demonstrated by 'Airport Collaborative Decision Making' (A-CDM). Failure or underperformance of any of the interlinked ICT systems may compromise the ability of airports to plan their use of resources to sustain high levels of air traffic, or to provide accurate aircraft movement forecasts to the wider European air traffic management systems. The proposed solution is to introduce further SERSCIS ICT components to manage dependability and interdependency. These use semantic models of the critical infrastructure, including its ICT services, to identify faults and potential risks and to increase human awareness of them. Semantics allows information and services to be described in such a way that makes them understandable to computers. Thus when a failure (or a threat of failure) is detected, SER-SCIS components can take action to manage the consequences, including changing the interdependency relationships between services. In some cases, the components will be able to take action autonomously -e.g. to manage 'local' issues such as the allocation of CPU time to maintain service performance, or the selection of services where there are redundant sources available. In other cases the components will alert human operators so they can take action instead. The goal of this paper is to describe a Service Oriented Architecture (SOA) that can be used to address the management of ICT components and interdependencies in critical infrastructure systems.
