Virtual private network as a service — A need for discrete cloud architecture

Cloud Computing in recent years has become a buzz word in the world of information technology. Cloud computing also referred as on demand computing has been extensively adapted by various organization irrespective of their scale and nature of work, essentially because of kind of flexibility, ease, scalability, less overhead and cost benefits that cloud computing provides. In recent years we have seen discrete and unique cloud implementations resulting in automation of complicated business processes at a never imaginable cost. Cloud computing provides three basic architecture to cater the needs of different users i.e. IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service). As the implementation of cloud computing is exponentially broadening and it is being implemented in newer and newer fields, need is being felt by cloud implementers to have unique service architectures for a specific implementation. In other words a unique cloud service architecture e.g. for Educational Establishments or e.g. a discrete service architecture for Virtual Private Network (VPN) if it is to be deployed through cloud. As Virtual Private Networks are a part of most of the network deployments all over the world connecting branches, business partners and outlets and providing seamless connectivity especially for SME's (Small-Medium sized Enterprises). Most of the organizations with VPN deployments want to reduce the operational cost, implementation cost and overhead associated with VPN's. This research paper is mere effort to study the need for discrete cloud architecture for the implementation of VPN service through cloud computing. This research paper introduces a unique cloud architecture VPNaaS (Virtual Private Network as a Service).
