A network of digital connections extend broadly across layers of city highways / routing paths.

network security / network traffic scanning

Basing network security on IP addressing: Would it be worth it?

Rather than layering security onto networks, the networks and carefully managed authorization policies can hinder attacks, but at an administrative cost.

Mastery of technology skills + knowledge.

Do new technologies make IT easier?

Technologies that automate and streamline network tasks and infrastructure can lighten the workloads of IT pros, but they can also create new burdens.

How and why to adopt SDN despite its dark side

Software-defined networking gives tighter control over network topology and management, and those not using it might find SDN is already supported in their networking gear.

Two developers collaborate on a project as they review code on a display in their workspace.

APIs pose the latest threat of networking-vendor lock-in

As software-defined networking becomes more dominant, the APIs offered up by one networking vendor can more severely limit interoperability with products made by others.

5 steps for modernizing enterprise networks

Software-defined networking, artificial intelligence, cloud, new Wi-Fi and 5G options, and network security can combine to improve performance of traditional networks.

SD-WAN

Is SD-WAN out to kill MPLS?

SD-WAN is something everyone's talking about but is it better than MPLS? My answer is yes... and it's easier to explain than baseball.

Why the cloud will never eat the data center

Even if traditional data-center tasks are all moved to the cloud, there will still be a need for on-site infrastructure that will ultimately require what looks like a traditional data center.
