The network edge is set for an evolution as SDN and the cloud reshape the concept of the enterprise data center.
Don't feel compelled to choose between white box and proprietary networking hardware just yet. Art Cole explains why.
SDN will be of limited benefit unless it can be extended into the WAN. Some vendors are working to make SD-WAN a reality.
As the dream of the fully virtualized data center comes closer to reality, the race is on to integrate SDN into the cloud stack.
Network infrastructure has a big role to play in the Big Data world, and solutions are emerging to solve the challenges Big Data creates.
The pressure is on for high-bandwidth networking in the data center, but is 100G worth it to the enterprise?
Improved application delivery is the ultimate goal of technologies like SDN and virtualization and should be the ultimate goal of the enterprise data center.
SDN doesn’t have to involve a rip and replace. Overlay networking, open switching formats and open source support a more gradual transition.
Optical cabling is on the rise in the data center. What challenges will fiber bring to the enterprise?
Forget about SDN hype. Network policy will be the primary topic for networking administrators in 2015.
2015 will see SDN deployments kick off in earnest, but that’s not all that lies in store for enterprise data center networking.
Ethernet is evolving along with the data center, and sometimes that means incremental improvements rather than giant leaps forward.
The application layer looks set to become a major focus for IT. Here’s a look at what to expect and how to plan for the app-centric future.
Advances in taking the SDN to the WAN are bringing enterprise data environments closer to the dream of a fully federated, distributed cloud ecosystem.
When it comes to SDN and the cloud, optimal connectivity will involve more than just bandwidth and throughput.
Details on former CEO Shaygan Kheradpir's resignation remain sketchy, though with Rahim at the helm, Juniper gets the leadership it has always deserved.
Big Data and SDN are more than just mutually beneficial. In fact, in the data environments of the near future, they will need each other.
ARM architecture looks capable of better serving mobile, cloud, virtualized, and software defined networking needs. Some vendors are already taking advantage.
"Inadequate networking could make your cloud more of a hindrance than a help to next-generation data functionality."
What issues could containers cause in a virtualized network, and what are vendors doing to address them?
As enterprises take their first steps towards SDN, how should they manage the transition for best results?
What will be the killer app for SDN, and does there have to be only one?
The student becomes the master as OpenFlow visionaries re-unite at VMware.
Handicapping the growth of the SDN market is a tricky game. But whether you are SME, SoHo, or hyperscale, there is a software defined network out there for you.
Technologies like the software defined network evolve within the confines of wide industry trends. These days, that would be the cloud.
SDN's flexible, dynamic nature creates new network monitoring and visibility problems. Here's what networking vendors are doing to solve those problems.
Programmability will bring unprecedented flexibility to the software defined network, but what about customizing the underlying hardware?
Just as networks take their first steps into virtual infrastructure, the data environment and its requirements are changing again.
Some networking vendors aim to unify multi-vendor, legacy data center silos into the interoperable environments private cloud requires.
Increasing reliance on the cloud is making the WAN critical to enterprise connectivity. Vendors are stepping up to deliver LAN-like functionality for the WANs of the future.
What are the practical benefits of intelligent networks, and how does network intelligence differ from SDN?
Data center spending often focuses on performance improvements. But what are the real culprits behind poor performance, and how can you fix it?
SDN application development efforts look set to increase the capabilities and value of software defined networks in the enterprise.
The enterprise isn't yet equipped to deal with the consequences of SDN, because no one knows what those consequences will be.
Advanced cloud architectures will require advanced network infrastructure in the data center.
The road to 100 Gbps+ Ethernet is proving more complicated than it first appeared, at least for those considering hyperscale deployments.
Network fabrics imply a flattened architecture that eschews centralized switching. So why are vendors still talking about core fabric switches?
Hyperscale implies massive infrastructure, but key technologies may wind up in standard enterprise settings as well.
Even with the advent of highly fluid virtualized data environments and SDN, choices like open vs. proprietary remain.
SDN must overcome several key challenges before it can make it through the hype cycle and establish itself on the other side.
