Beyond SDN lies AAN and the path to a truly optimized application environment.
Data center virtualization and the next wave of the cloud will demand what software defined networking has to offer.
Cisco makes the jump into services, but can it make the switch from dominant player to hungry newcomer?
Building an entire new SDN-optimized infrastructure is a daunting task. Perhaps the overlay approach on legacy networks isn't so bad.
All the activity coming from abstract resources can overwhelm anything still operating on the physical plane, including storage.
Stepping outside the SDN bubble, is the noise around SDN real?
In the grand scheme of things, the true value of software defined networking lies not in what it is, but what it does.
SDN can take you where no network has gone before, but you may have to rethink the forwarding table.
Despite widespread recognition that wide area networks will play a vital role in the move to distributed architectures, few enterprises seem willing to shore up their own infrastructure.
Open source and open standards are becoming increasingly important in the SDN sphere, but openness isn't a magic bullet.
Many enterprises are bent on deploying hybrid clouds in the coming year, but how should they be networked?
Hyperscale data environments are coming. Contributions to Facebook's Open Compute Project reveal surprising strategies for maximizing them.
SDN vendors and early adopters are dreaming big. But will their dreams become reality, or will the results prove to be less than they'd hoped for?
The acquisition of Corente will bring Oracle new WAN virtualization and wide area SDN capabilities. What's Oracle's end game?
Software defined networking puts the spotlight on the controller—but does it have to?
The U.S. Court of Appeals this week struck down the FCC Network Neutrality order. What does this mean for the Internet as we know it?
Network hardware, even the lowly router, will have to change its behavior if it is to adequately support the virtual data center.
Software defined networking over the WAN will someday be a necessity. What challenges must vendors solve to make it a reality?
Before software defined networking can achieve its lofty goals, the orchestration pieces need to fall into place.
Now that the enterprise has entered the SDN deployment phase, its time to start thinking about what you'll actually do with it.
SDN, network fabrics and increased intelligence will help with crushing data loads, but so will plain, old raw bandwidth.
Even SDN won't provide everything that wide area data environments require. How can enterprises optimize their distributed infrastructures?
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 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.
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.
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.
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.
Startups and big vendors alike work to make SDN deployment easier with new platforms and solutions.
The new generation of SAS technology promises to turn SAS from a simple drive interface into a fully functional storage fabric.
Enterprise networks are turning to alternatives like app acceleration and WAN optimization instead of just piling on the bandwidth.
Key technology partnerships are ensuring that network infrastructure will soon break free of the physical world and rise into the cloud.
Leading vendors like Brocade, Big Switch Networks, and F5 are developing orchestration solutions aimed at making the cloud more than just a scaled-out data center.
Don't discount the importance of hardware in a software defined network. Switches in particular remain crucial to network functionality.
SDN is still a long way from fulfilling its much-hyped promise, but that's not a bad thing. Art Cole explains why.
