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.
The top 9 trends in network technology for 2019
In the new year, expect SDN and SD-WAN to come back down to earth. Meanwhile, multi-cloud, edge computing and intent-based networking will ramp up. Plus, data centers are not dead.
How 3 benefits of SDN can help small businesses
As SDN matures and evolves from its original definition, it’s getting harder for small businesses to ignore the benefits of SDN, like better visibility, security and efficiency.
A 7-step checklist for designing a cloud migration plan
Enterprises want their applications to be portable and able to shift easily among multiple cloud providers. To do that, putting together a good cloud migration plan is a must.
Hybrid cloud strategies should be reimagined as multi-cloud
Everyone is talking about hybrid cloud strategies, implying this framework is how all IT resources will be deployed in the future. It sounds great — on paper. Proponents tout hybrid cloud’s ability to tap into both public and private resources to build scalable applications that can be managed and secured as if they were being delivered privately — a way to have your cake and eat it, too.
Sorting the hype from the truth with intent-based networking systems
Everyone is talking about intent-based networking these days, but because there is no great agreement on what it is, many people are trying to twist that around. The latest entrant to this is Cisco, who is trying to co-opt the trend. Where do we go from here?
Power / Performance Determinism
The new AMD EPYC processors feature two new distinct modes, power determinism and performance determinism. These modes enable a business to optimize based on greatest overall performance or on greater predictability in clock speed.
