New Architecture Design of Cloud Computing Using Software Defined Networking and Network Function Virtualization Technology

Cloud computing is a new technology model that consists of a pool of configurable resource and multiple data centers in distributed areas. It offers a service over the internet for users using virtual data, and who share resources for storing and accessing data from anywhere. Cloud computing supports big-scale platforms that consist of thousands of servers and hundreds of switches. Currently, the cloud is suffering from many issues in term of management, security and other essential aspects. This paper discusses integrating Software Defined Networking (SDN), with Network Function Virtualization (NFV) based on cloud computing, to eliminate some of the existing security issues faced by cloud computing. This research paper proposes a new architecture design by taking advantage of the NFV technology to build a virtual security mechanism such as Network Intrusion Detection System (NIDS).
