This research was created with the intention of analysing the interrelationship between cost and security in Cloud Computing for Irish SMEs. The main emphasis is placed on analysing the Multi-perspective framework of cloud computing in relation to companies in Ireland. Five segments have been created to makes the research comprehensive. The first section outlines the core aim and objectives of the research and the significance of the study. The next section illustrates the knowledge obtained by reviewing a vast range of articles and journals. The main challenges and benefits of using Cloud-based services were also discussed in this section. In section three, the methods used in the research have been identified, along with the quantitative and qualitative analyses of the primary data. The fourth section interprets the data collated and analysed. The final section wraps up the project with the discussion and analyses of the findings.
