Concepts of Cloud Computing and Protection of Data in Cloud Computing
This study is to review the concepts of cloud computing and different security techniques and protecting data in the cloud, which can be implemented in three different service models, such as Software-as-a-Service (SaaS), Platform- as-a -Service (PaaS, and Infrastructure-as thea- service (IaaS).
Abstract
The internet has changed the world in a strong way.it has traveled from the concept of parallel computing to distributed computing to grid computing and recently to cloud computing. Cloud computing is a recent trend in Information Technology that moves computing and data away from desktop and portable personal computers into large data center. The main advantage of cloud computing is the user cannot pay for infrastructure, its installation, required man power to handle such infrastructure and maintenance. Cloud computing technology is collecting success stories of savings, ease of use, ease of access and increased flexibility in controlling how resources are used at any given time to deliver computing capability. Cloud providers who can demonstrate that they protect personal information may be more truthful and therefore more attractive to potential Cloud users. The cloud service can be implemented in three different service models, such as Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS). Data security and privacy protection issues are relevant to both hardware and software in the cloud architecture. This study is to review the concepts of cloud computing and different security techniques and protecting data in the cloud.
