Cloud Computing: Issues and Challenges

TLDR

Cloud computing is widely expected to transform the ICT industry. The paper seeks to identify and highlight key challenges and issues of Cloud computing, especially interoperability. The authors examine Service‑Oriented and Grid computing paradigms to contextualize Cloud computing, then identify adoption‑related challenges.

Abstract

Many believe that Cloud will reshape the entire ICT industry as a revolution. In this paper, we aim to pinpoint the challenges and issues of Cloud computing. We first discuss two related computing paradigms - Service-Oriented Computing and Grid computing, and their relationships with Cloud computing. We then identify several challenges from the Cloud computing adoption perspective. Last, we will highlight the Cloud interoperability issue that deserves substantial further research and development.
