A Systematic Literature Study on Definition and Modeling of Service-Level Agreements for Cloud Services in IoT

Abstract

The cloud computing paradigm provides remote computing resources to the cloud service consumers and businesses. When combined with Internet of Things (IoT), both technologies open up a wide range of new possibilities for more agile and flexible applications. However, guaranteed quality of service is essential in provisioning of cloud services, which makes Service Level Agreements (SLAs) a focal point in the cloud computing and IoT ecosystem. The SLA definition and modeling phase is crucial in establishing SLAs between service providers and consumers. This paper identifies that the research on definition and modeling of SLAs for cloud services in IoT is widely dispersed and there is a lack of a systematic and comprehensive literature review. Thus, in this paper we build on top of a previously conducted systematic mapping study on management of SLAs for cloud computing and IoT to perform a comprehensive systematic review and discuss sub-categorization of the definition and modeling aspects of SLAs for cloud services in IoT. Furthermore we analyze the extracted relevant literature, present commonalities in the studies, identify gaps and discuss opportunities for further research in the area.

Ultra‐reliability and low‐latency communications on the internet of things based on 5G network: Literature review, classification, and future research view

“…68 For example, a few safety contracts can bring high value and Service Level Agreements (SLAs). 69 On the other hand, various operators and companies are experimenting with low-latency offerings. For instance, Verizon is leveraging its 5G multi-access edge-computing platform through a partnership with Amazon Web Services (AWS).…”

Service Level Agreements for 5G and Beyond: Overview, Challenges and Enablers of 5G-Healthcare Systems

“…Literature reports on SLAs for cloud computing and IoT are numerous. The studies in [ 32 ] and [ 33 ] identified over 300 existing works related to SLAs in the domain of cloud services in IoT. To present a systematic and comprehensive literature review on the topic, authors in [ 32 ] did a systematic mapping study on management of SLAs for cloud computing and IoT and categorized their findings into various SLA stages and aspects and analyzed select reports in [ 33 ].…”

Notably, the authors concluded that there are few studies focusing on concrete metrics for qualitative or quantitative assessment of quality of service (QoS) in SLAs, which highlights a need for in-depth research on metric specification and measurement methods for SLAs.…”

Functional Safety Networks and Protocols in the Industrial Internet of Things Era

“…This trend started roughly at the beginning of the 1990s and progressively enforced over the years, thanks to the improvements achieved by such networks in terms of performance indicators, such as timeliness, reliability, dependability and scalability. Today, this scenario is further revolutionized by the adoption of the Industrial Internet of Things (IIoT) [ 5 , 6 ] where a pervasive communication infrastructure allows connection of cloud systems, controllers, industrial equipment, sensors and actuators to dramatically improve the performance of manufacturing systems in terms of product quality, production efficiency, safety and security [ 7 , 8 ].…”
