Exploratory Study of PaaS Adoption Determinants Using Experimentally Augmented Delphi Process

摘要

Platform as a Service (PaaS) is one of Cloud Computing service models [1]. Adoption factors associated with PaaS specifically are not explored. Management of database systems, middleware and application runtime environments is automated in PaaS [2]. PaaS issues and requirements were collected in three rounds from information technology experts using a novel Delphi technique augmented with experiment. PaaS experiment was required to have understanding of the factors and requirements. In this paper, PaaS adoption factors by an organization are systematically collected and explored. Evaluation of the adoption factors was based on experiment in a private cloud for an organization undergoing a transformation toward PaaS computing. It was found that technology, organization and environment (TOE) factors are relevant in this context. Based on collected data from Delphi process and the associated experiment, TOE adoption model for PaaS is proposed.
