Over time, the importance of information and the need to use it are increased. Cloud computing provides data and computing resources to clients as a service. However, cloud computing provides to the end user computing recourses such as software, hardware, and information as a service through the available interface over the Internet to be with more advantages to make the information available and accessible whenever is needed, by using the cloud computing services offers these services. The main purpose of this literature review paper is to develop an understanding of cloud computing adoption. Moreover, this paper forms the basis of our theoretical study. In particular, we review the state of the art of cloud computing and discuss about it aspects and features. In addition, we provide a set of cloud readiness criteria and review cloud migration in some countries that have already shifted to cloud. In this paper, we investigate the readiness to provide cloud services locally, as well as the chances and challenges of combining cloud services with existing infrastructure. Furthermore, the telecom sector infrastructure is suitable to provide cloud services, as the first step to provide the cloud into the network infrastructure of such providers, enabling and enhancing the telecom sector services and infrastructure.
