Software Defined Networks
Notes from our Vice President of Technical Services
Traditionally the desire for stability in operations and agility in development do not align. The rapid innovation and updates in development exceed the ability of network systems to support them. Weeks could be needed to adjust a system of routers, switches and firewalls to support a new update which was deployed in minutes. Software Defined Networking (SDN) is combating this problem by increasing the responsiveness of operators in order to meet the growing demand of the changing industry.
Instead of having to manage all the unique configurations for each of the devices in your network individually, SDN automates this process with consistency. The uniformity created through software defined networks increases network agility and efficiency. Cisco’s flagship product, Application Policy Infrastructure Controller (APIC), provides automation with agility across virtual and physical resources in your network. The declarative nature of APIC directs the necessary tasks to the resources of a network, reducing the reliance on programmers knowing all the hundreds of features of each tool. The intelligence of APIC removes the complexity of network adjustments with the central management and consistency of software defined network solutions.
Companies that apply developer-like ideas to Network Management with Software Defined Networking will not have to deal individually with each of the network devices end-to-end, and instead, they will have the ability for APIC to only once have to apply a change versus writing script or utilizing a tool. Benefits of SDN include rapid infrastructure deployment, unified policy from end to end, and increased capacity with less equipment. The consistency, automation, and efficiency of software defined network’s central management reduces human errors, lowers costs and increases responsiveness. SDN allows companies to keep up with the innovation and development that is rapidly taking place.
