Architecting the Network for the Cloud using Security Guidelines

Abstract

Cloud computing is the latest emerging technology which offers reduced capital expenditure, complexity, operational risks, maintenance, and increased scalability while providing the services at different abstraction levels, namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). A new approach called cloud networking that enables and adds the networking functions and resources to cloud computing and provide the means of dynamic and flexible placement of virtual resources that crossing over provider borders. It also allows various kinds of functionalities and optimization techniques, e.g., reducing network load. This approach brings out and enables new security challenges. This paper presents a new security architecture, which enables the user of cloud networking to illustrate the security requirements and apply them in the cloud networking infrastructure.
