Analysis of Security Vulnerabilities of Cloud Computing Environment Service Models and Its Main Characteristics

We are currently observing a huge paradigm shift by different organizations moving their information technology services from enterprise-based data centers that run on different dedicated servers on their premises to cloud computing environment. Organizations are renting these services on demand basis from large cloud service providers that build and manage various large scaled data centers consisting of high capacity platform resources, like Network, hardware, and software resources. As an emerging and distributed computing environment, cloud computing also has a number of security issues associated with its main key features and its primary service delivery models. This research article will discuss, analyze, and address these different cloud computing service delivery models (Software as a service, Platform as a service, and Infrastructure as a service) and those cloud services primary attributes security issues.
