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.
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.
A zero-trust model limits access and permissions according to a defined set of parameters that enterprises specify for each application. Learn what this means for network security.
When deciding which applications to move to a cloud data center, enterprises should consider network bandwidth requirements and latency, among other factors.
Several dynamics are driving the need for 400 GbE infrastructures, including the increase in server density, private cloud applications and network edge data.
Traditional SDN controllers use northbound and southbound APIs to communicate. But software-defined WAN controllers don’t rely on those same SDN protocols
The key benefits of SD-WAN architectures include better network redundancy, efficient MPLS connections and added flexibility to deploy new services remotely
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 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.
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.
