Has SDN run its course, or has the architecture simply evolved? In many current products, data centers and cloud environments, SDN may be closer than you think.

Despite its advantages, what are the top disadvantages of SD-WAN?
Cost, complexity, security, training, troubleshooting and software bugs are some of the top disadvantages of SD-WAN. See how these issues affect SD-WAN deployment.
What is Cisco Smart Licensing and how might it benefit my business?
Cisco Smart Licensing, the networking vendor’s fairly new approach to software licensing, aims to provide customers with more visibility and control over their licenses.
What is the purpose of an SD-WAN gateway?
Software-defined WAN architecture has adapted with the growth of cloud services, resulting in a cloud-based model that uses SD-WAN gateways to handle traffic and control.
How do cloud data centers affect network bandwidth requirements?
When deciding which applications to move to a cloud data center, enterprises should consider network bandwidth requirements and latency, among other factors.
How do SDN protocols compare to those used in SD-WAN?
Traditional SDN controllers use northbound and southbound APIs to communicate. But software-defined WAN controllers don’t rely on those same SDN protocols
How SD-WAN architectures improve network flexibility and efficiency
The key benefits of SD-WAN architectures include better network redundancy, efficient MPLS connections and added flexibility to deploy new services remotely
How do network virtualization and network abstraction compare?
Network abstraction and virtualization are similar, but they do have significant differences, as well. All network virtualization is abstracted, but not all network abstraction qualifies as network virtualization. Abstraction is a lower-level concept, while virtualization is a higher-level concept.
Intent-based networking vs. SDN: How do they differ?
Intent-based networking and software-defined networking are similar in many aspects, but they also differ. Both technology approaches rely on a centralized controller to manage distributed devices on the network, as opposed to individually managing each device from its own management console, which is typically a command-line interface. The goal of both approaches is to abstract the management from individual devices and align it closer to how the business needs to operate.
What’s the difference between multi-cloud vs. hybrid cloud strategies?
Cloud computing pools resources that are provisioned and orchestrated on the fly, enabling IT to respond quickly to changing business needs. This kind of flexibility means a clearly defined cloud strategy is now an essential element for every successful IT department. The question is no longer if IT will use the cloud, but instead how it will use it.
