As-a-Service: Firewalls, Storage, Bare Metal, Hypervisors
For enterprises and SMBs alike the combination of SDN and NFV more or less brings the power of the cloud to the network. Its flexibility. Its scalability. Its redundancy. Its ease-of-use. Next to that, it gives SMBs low-cost access to high-end IT services that were previously out of their reach. For enterprises on the other hand, it may bring significant cost reductions when it comes to their IT deployments.
Through the combined use of Software Defined Networking and Network Function Virtualization, organizations are perfectly equipped to flexibly meet ultimate hybrid IT architecture requirements. For a wide variety of use cases at the edge including hybrid IT, Internet of Things (IoT), Industry 4.0, and data compliance management, to name a few. It allows for an easy roll-out of IT functionality ‘as-a-service’, even on-demand, catering to the needs of cloud-like pay-per-use business models. You may think of IT functionality such as firewalls, load balancers, storage solutions, bare metal, VMs, hypervisors, backup & disaster recovery, you name it. What’s more, the combination of SDN and NFV into one solution uniquely provides the opportunity to interconnect computing resources like these in a highly dynamic manner. Again, at the edge, meeting global as well as regional needs of SMBs and enterprises. SDN and NFV combined also allows for easy setup of data center failover locations; executing multi data center strategies; as well as flexible and scalable connectivity between different office locations. In fact, potential use case examples with SDN are almost endless.
Flexibility, Redundancy and Cost-Reduction
In the introduction and throughout this article we have emphasized the benefit of flexibility that Software Defined Networking combined with Network Function Virtualization can bring us when deploying IT infrastructures. Flexibility truly is incredibly important for safeguarding future IT deployment needs. The relentless adoption of cloud computing, IoT, and big data will drive immense traffic growth. This increasingly requires networks that are smart and elastic enough to support all of these digital transformation initiatives. SDN/NFV powered networks including the globally available Zumiv Elastic Network are perfectly capable of meeting these elasticity needs, certainly if the SDN controller is well designed and network intelligence conditions have thus been met.
A new IT infrastructure deployment model is actually needed to address the imminent challenges that organizations worldwide are facing when adopting cloud computing, hybrid IT, edge computing, 5G, Internet of Things (IoT), and big data. A model that brings more flexibility in service provisioning and control. An agile model flexibly supporting on-demand services delivery while offering instant scalability options for dynamic applications. A model which seamlessly supports deployment across multiple environments including on-premise, private cloud, hybrid cloud and multi-cloud.
When smartly designed, SDN/NFV powered networks can meet all of these needs, now and in the near future. It can provide a solid foundation for driving better data center economics with significantly enhanced operational efficiencies and reduced Capital Expenses (CAPEX) and Operating Expenses (OPEX). For end-users and service providers, it can accelerate service innovation and provisioning while addressing the interconnectivity and interoperability issues which often hold back traditional equipment-dependent networks.
