Cloud Service Selection and Evaluation Techniques

Cloud service selection and evaluation encompass a suite of systematic methods designed to guide organisations and developers in choosing the most appropriate cloud offerings from a proliferating market of providers. Central to this endeavour is the need to balance multiple quantitative and qualitative criteria, including performance, cost, scalability, security, compliance and reliability. Approaches typically adopt multi-criteria decision analysis frameworks to model stakeholder preferences and trade-offs, employing techniques such as Analytic Hierarchy Process, Technique for Order of Preference by Similarity to Ideal Solution and hybridised algorithms that integrate fuzzy logic, linguistic variables or probabilistic terms to handle uncertainty. Emerging methods seek greater automation and agility through parameter-ranking priority weightage schemes and sensitivity analyses, while domain-specific adaptations—for instance in precision farming or scientific computing—demonstrate the global applicability of these techniques. Practical implementations often feature decision support tools and brokering mechanisms that streamline data collection, comparison and visualisation, thereby empowering users to make informed, unbiased choices aligned with their operational goals.

Cloud Service Selection and Evaluation Techniques publication trend

The graph below shows the total number of articles in cloud service selection and evaluation techniques across all publications each year (not limited to Nature Index journals).

Technical terms

Multi-Criteria Decision Analysis (MCDA): A family of formal methods for evaluating and ranking alternatives when multiple, often conflicting, criteria are involved.

Analytic Hierarchy Process (AHP): A structured technique for decomposing decision problems into hierarchies, assigning weights via pairwise comparisons, and synthesising scores for alternatives.

Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS): A ranking method that identifies solutions closest to an ideal point and furthest from a nadir point based on normalised criteria distances.

Best Worst Method (BWM): A weighting technique wherein decision-makers specify the most and least important criteria, facilitating consistent derivation of criterion weights.

Parameter-Ranking Priority Level Weightage (PRPLW): An algorithm that assigns criteria to priority levels and computes weighted averages to simplify and accelerate vendor selection.

Quality of Service (QoS): A set of measurable performance attributes—such as latency, throughput, availability and security—that characterise a cloud service’s operational quality.
