This article focuses on risks in cloud computing when designing, selecting, and configuring cloud services. Cloud computing has brought many benefits, such as low cost and simple management. However, it also comes with many risks, including old ones such as lack of integrity, accountability, and trustworthiness, and also insider misuse. And there are new risks as well. For example, “the scale and distributivity of some of the clouds” is questionable. Security and privacy in the cloud is an open problem to the research community. Especially, as more and more personal or sensitive data is stored in the cloud due to the large scale, people have more concerns about information leaks and privacy issues. Information scandals related to the cloud have also happened recently, which further proves the existing privacy risks with cloud computing.

I totally agree with the author’s opinions. People may ignore the risks when dealing with cloud services. This article is a good reminder of the serious risks they may face now or in the near future. We need to be more cautious about cloud computing since many risks have not yet been fully addressed.
