Evaluating and Ranking Cloud IaaS, PaaS and SaaS Models Based on Functional and Non-Functional Key Performance Indicators

Abstract

With the recent maturity of Cloud computing technology and the flexibility of the Cloud services, the offering of Cloud services has spread exponentially. Different Cloud service providers offer their services highlighting different features of their services. Because of the diversity of Cloud services and their highlighted features, the choice of the most suitable Cloud service is a complex problem for the Cloud users. Many Cloud users are unable to identify the Cloud services that best suit their needs and thus choose an unsuitable Cloud service, which results in financial loses as well as time delays. To this end, in this study, we propose an efficient three layered framework for evaluating and ranking IaaS, PaaS and SaaS Cloud services. We identified the functional and non-functional key performance indicators (KPIs) for Cloud services from 6 KPI classes. We classified these KPIs with respect to their types and criticality so that the Cloud user can easily choose according to his needs. The relative importance of the KPIs was determined using CRITIC method. We combined the KPIs values and their relative importance for an overall evaluation and ranking of the Cloud services using Vikor method. A case study is also presented for a step by step demonstration of the proposed method.

Seguridad de la Información en la Nube: Una revisión sistemática

“…Es por ello que es de suma importancia evaluar los servicios de SaaS, es esencial considerar la accesibilidad de la interfaz de usuario para una amplia variedad de usuarios y abordar adecuadamente la cuestión de la propiedad de los datos para garantizar que los derechos de los clientes se protejan de manera efectiva. Estos dos aspectos son fundamentales para evaluar la calidad y la seguridad de los servicios de SaaS mencionados en (Nadeem, 2022).…”

“…La revisión sistemática nos brindó una definición de aquello que implica nube tal como menciona (Al-Ghuwairi et al, 2023) asimismo reforzando dicha idea es reforzada por (Blanco et al, 2023) quién indica que nube no solo queda en un concepto, sino que involucra diferentes servicios que son empleados por los clientes. Cuando hablamos de administrar y monitorear la infraestructura (Mohammed et al, 2021) indica que es de suma importancia evaluar los servicios de SaaS, es esencial considerar la accesibilidad de la interfaz y a su vez (Nadeem, 2022) señala la garantía que debe existir de manera tal que se asegure la protección de manera efectiva de los datos.…”

Infrastructure-as-a-Service Ontology for Consumer-Centric Assessment

“…Aiming to facilitate cloud customers as our work, the author in [2] recently proposed a KPI-based framework for evaluating and ranking IaaSs, PaaSs, and SaaSs to help cloud users identify cloud services that best suit their needs. However, the framework consists of only 41 KPIs, lacking several practical details for effective decision making.…”

Decentralized Attestation and Distribution of Information Using Blockchains and Multi-Protocol Storage

“…non-centralized coordination of the execution controlled and observed by distributed parties [15]. Cloud platforms such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform focus on providing infrastructure, software platforms, or applications as a service [27]. While infrastructure services commonly concern specific physical or virtual servers, the services for platforms and applications hide infrastructure such that, possibly, non-centralized infrastructure might be used under the control of the provider.…”
