“…Figure 1 depicts a simple agreement on a set of QoS metrics as well as penalties (service credit) between a cloud provider and an application provider; simplified for demonstration purposes. Several monitoring systems [9] have been proposed to enable trust and SLA enforcement. In summary, proactive monitoring tools are aimed at violation prediction and resources management, while reactive counterparts can deal with the aftermath of SLA violation such as those related to responsibility and accountability.…”

“…A broader awareness covering these layers would improve monitoring capabilities for the sake of better understanding of the system performance, analysis, and failure tracking. The contribution of this article is to propose a conceptual framework based on best practices explored by the state-of-the-art research [1] [16][17] [18]. To realise an effective SLA practice based on our suggested consideration, we propose a trustless approach for conducting SLA management tasks in the context of IoT.…”

“…An SLA speci es the services to be delivered in a business relationship and exclusions; it describes how the service provider's performance will be measured and provides a legal structure for relationship management including contract monitoring and dispute resolution. It also speci es the remuneration for core services and expenses incurred and o ers a means to calculate the cost of additional (non-core) services [61,62]. A key advantage of SLA is that it prepares both provider and customer to co-create the service, with the potential for identifying tasks and information that need to be performed or obtained before the service can be delivered.…”

Inventory model optimization revisited: Understanding service inventories to improve performance

Services are becoming increasingly important in the modern economy for both service and manufacturing rms; however, the inventory literature is focused mainly on physical goods and, thus, only few studies have considered services in optimization. Further to that, the traditional service management literature relies on an extremely narrow de nition of inventory that excludes services because they are perishable. Thus, there is a lack of research on possible links between inventory optimization and service management. However, according to a new service inventory approach, business components such as tasks or information, as di erent from physical goods, can be performed and stored in anticipation of service demand as a form of service inventory, that is, inventorying by anticipation rather than delaying the service. This paper aims to contribute to this lack of research by proposing a service inventory optimization model that integrates a service orientation to optimize tasks and information to be performed in advance. In contrast with the traditional inventory models where the objective is to optimize physical items, in this approach, physical products (whenever included) constitute only mechanisms for service provision. This service inventory model contributes to the optimization of the quantity of tasks or information to be anticipated and, thus, provides customers with a number of bene ts.

“…To establish an operational governance control in the sharing economy, this paper utilizes the concept of SLA [25], which describes the obligations that service providers must comply with when delivering a specific service to consumers. For instance, in the cloud service, an SLA can state that the network throughput must be higher than 100 Mbps; otherwise, the consumer receives 50% of its payment back.…”

SLA-Based Sharing Economy Service with Smart Contract for Resource Integrity in the Internet of Things

Recently, technology startups have leveraged the potential of blockchain-based technologies to govern institutions or interpersonal trust by enforcing signed treaties among different individuals in a decentralized environment. However, it is going to be hard enough convincing that the blockchain technology could completely replace the trust among trading partners in the sharing economy as sharing services always operate in a highly dynamic environment. With the rapid expanding of the rental market, the sharing economy faces more and more severe challenges in the form of regulatory uncertainty and concerns about abuses. This paper proposes an enhanced decentralized sharing economy service using the service level agreement (SLA), which documents the services the provider will furnish and defines the service standards the provider is obligated to meet. The SLA specifications are defined as the smart contract, which facilitates multi-user collaboration and automates the process with no involvement of the third party. To demonstrate the usability of the proposed solution in the sharing economy, a notebook sharing case study is implemented using the Hyperledger Fabric. The functionalities of the smart contract are tested using the Hyperledger Composer. Moreover, the efficiency of the designed approach is demonstrated through a series of experimental tests using different performance metrics.
