Utilização do OpenStack em conjunto com as tecnologias SDN - Software-Defined Networking e NFV - Network Functions Virtualization

Abstract

Cloud computing is a technology that has had great acceptance and its adoption is increasing, all this, leveraged by the optimization of the resources of computing and hardware on demand through the internet. OpenStack has emerged as a solution for open source cloud computing and infrastructure as a service, enabling orchestration, management and automation of resources. In this line, the emergence of Software-Defined Networking (SDN) and Networking Functions Virtualization (NFV) technologies that are based on software virtualization, where SDN is an emerging architecture with the function of separating the control plane and data plane into network hardware, and NFV transfers the network functions from the hardware to generic devices, concentrating the different functions into a single, versatile and expandable appliance. Thus, the present work aims to present the OpenStack platform, the SDN and NFV concepts and discuss the use of these technologies together. The study has as a methodology to conceptualize cloud computing, virtualization, OpenStack, SDN and NFV, through a bibliographical research in order to deepen and update the knowledge on the themes for sequential discussion and to abstract the experience obtained by local and distant researchers. SDN and NFV technologies are expected to become standard technologies for future network deployments. As a complete cloud computing environment is required for these applications, OpenStack becomes a viable solution even because it is already a reality in large enterprise IT environments.
