Abstract:

Cloud computing is familiar to all, as an innovative technology, as the new generation of the internet as a good opportunity for new ideas in business. It’s a term that refers to sources and computer systems available on demand through the internet.

Cloud computing is increasingly used for various needs and convenience. It can provide a number of integrated computer services without being bound by local resources in order to make it easier for the user, and those resources include data backup, storage space and self-synchronization. The adoption of cloud computing is not as complex as many organizations have thought and by moving the applications and hardware out of the organization the user can focus on its core strategies.

The cloud-based model uses delivery of information technology services accessible through the network. Networks can be part of the internal infrastructure organizations - intranet, or external, such as the Internet or mobile networks. The use of internal networks and services is preferred by organizations - private Cloud. External networks and services offered by public cloud services pose significant risks. The main risks associated with public cloud computing are security and access control (accessibility).

Public cloud computing - offers attractive advantages to higher education, delivering infrastructure, services, and software on demand through the network. For example, it has the potential to reduce information and communications technology (IT) costs by virtualizing capital assets such as disk storage and processing cycles into a readily available, affordable operating expense. Sometimes selecting a public cloud offering can create risk around security, privacy, interoperability, or performance. When it does, universities should consider private cloud deployment models to realize scale on demand, rapid platform deployment, and lower costs and carbon emissions while minimizing risk.

This paper aims to investigate Cloud Computing and discusses the drivers and inhibitors of its adoption, a review of different security issues like trust, confidentiality, authenticity, encryption, on how to overcome these issues.
