Abstract

The usage of service-level agreement (SLA) to ensure smooth negotiations, easy management, and provision of resources make it a reliable tool to ensure service guarantees in a network. Low-latency Internet connectivity services provided by edge servers such as a Cloudlet deployed in small–medium enterprises (SMEs) can benefit from SLA. This is due to that SMEs are exposed to financial issues and through the use of SLA, SMEs such as a coffee shop can be able to attract consumers plus minimize Cloudlet operational cost. The operational cost is minimized through using the SLA to manage and provide effective resources which eliminate SLA violations in the network. The decrease in SLA violation occurrence has a positive effect on the operational cost SMEs must spend to lease resources and Internet packages from providers. The objective of this study was to demonstrate the effectiveness of SLA in minimizing Cloudlet operational costs using a coffee shop scenario. This was achieved through the use of a CloudSim Plus tool to simulate the SLA in a network. The results show that the management of resources in the network and the monitoring of the agreed SLA eliminate SLA violations and further minimizing operational cost.
