Analyzing Service Level Agreements for Optimal Quality of Service in Cloud Computing

Abstract

The several factors that aid in the formation of Service Level Agreements (SLAs) between service providers and users determine the management and establishment of SLAs in the cloud. Both the generation of SLA metrics and the providing of services are determined by these criteria. Companies and consumers alike must settle on a method for selecting a service provider. Researching and comparing the top providers on the market today under the same circumstances is an intensive procedure that is necessary when picking the proper service for every customer. The biggest problem for clients when choosing an IaaS provider is the lack of openness and standardisation in the industry. When making a scientifically-based preference for one service over another within the same category or supplier, this study is crucial. After a year of testing VNS and SSaaS, this study compared Amazon and Microsoft Azure's SLA quality of service across two major providers using identical tools, server settings, geographic region, time, and factors. When comparing the two firms' SLAs from the user's point of view, we found that their network factors and performance variations were very comparable. when a consequence of the virtualization technology they employ, AWS provides better values when the number of client connections increases. AWS surpassed Azure in terms of service credit, free tier account providing, and Linux usability.
