Cloud Computing Antecedents, Challenges, and Directions

Abstract

Cloud computing has recently emerged as a new model for hosting and delivering services over the Internet. It has many advantages, such as, increasing the capacity or adding capabilities without investing in a new infrastructure to fulfil the needed technological requirements in a fast and automated manner. It has obviously grown and its growth is impressive. However, the more information about people and business are used in the cloud, the more concerns raised about the security of its environment. Also, there are some challenges when using this service. In this paper, a survey about the main concepts of cloud computing along with some examples of the appropriate usage of its services is presented. This will help in making the right choice of using cloud computing services. The challenges of using cloud computing is introduced as well.
