Even SDN won't provide everything that wide area data environments require. How can enterprises optimize their distributed infrastructures?
Articles by Arthur Cole
Truly open networking is a nice dream, but is it really what the enterprise needs? Open source and open standards create challenges of their own.
Software defined networking's benefits are clear, but that may not be enough to justify a full rip and replace of all network devices. What else can organizations do?
Software defined networks and the distributed data center will require intelligence, interoperability, and agility at the network edge.
Enterprises just finishing up the conversion to 10 GbE still have a fair amount of work to do to achieve a truly dynamic data center.
SDN announcements from networking vendors like Cisco, Arista, Juniper, and Brocade mark the next step in the software defined revolution.
Art Cole explores hardware and software solutions aimed at optimizing energy consumption and improving the energy efficiency of your network and data center.
SDN may one day change everything you know about the network. Fear of this change will hold you back, but perhaps some caution is warranted.
Even private clouds often rely on public infrastructure. How can Ethernet address the resulting concerns, and which vendors are on top of the issue?
The fully software defined data center looks closer than ever, but before it can be realized, the software defined movement must address the storage question.
Software Defined Networking is the Next Big Thing, according to its proponents. But is it really, and does everyone truly need it?
Virtualization, cloud, and SDN demand optimal WAN performance. Check out some vendors promising to provide just that.
Technology serves as a means to a business end. In the case of SDN, the end is the on-demand data center. What does that mean, and how are vendors working to get there?
New network processing technology looks set to speed us into the SDN, mobility, Internet of Everything future.
As data environments change, so too must the data center itself. That includes its network infrastructure.
Fiber is emerging as the go-to technology for future-proofing the enterprise data center against growing bandwidth demands. Art Cole explores some solutions.
New networking solutions promise to curb energy consumption in the data center, a vital concern given the current upward trend of IT energy use.
Software defined networks demand a high level of visibility. What are vendors doing to address that need?
Proprietary or open source? Software defined networking puts the debate front and center. Arthur Cole weighs the options.
New and next-gen technologies set to improve enterprise network user experience.
Contemplating cloud-based services? Art Cole recommends making sure that your SLA covers these critical networking issues.
All the bandwidth in the world won't mean a thing if you lose availability. Invest in measures to prevent costly network downtime—it's worth it.
Some fear that increased traffic from the cloud will prove too much for the Internet to handle. Here's why that won't happen.
Converging evolutions in infrastructure look poised to radically remake data environments. What does this mean for networking?
As SDN continues its growth from buzzword to reality, enterprises must consider how much application awareness and automation they really need.
