Preparing for the Application-Driven Data Center

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.

New Tools for the Distributed Data Center

Advances in taking the SDN to the WAN are bringing enterprise data environments closer to the dream of a fully federated, distributed cloud ecosystem.

SDN and Cloud Connectivity in Distributed Data Environments

When it comes to SDN and the cloud, optimal connectivity will involve more than just bandwidth and throughput.

SDN and Big Data: Enterprise, Analyze Thyself

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 Solutions for the Data Center Network

ARM architecture looks capable of better serving mobile, cloud, virtualized, and software defined networking needs. Some vendors are already taking advantage.

Don’t Skimp on Cloud Connectivity

"Inadequate networking could make your cloud more of a hindrance than a help to next-generation data functionality."

Containers and the Virtual Network

What issues could containers cause in a virtualized network, and what are vendors doing to address them?

SDN Deployment: Managing the Pace of Change

As enterprises take their first steps towards SDN, how should they manage the transition for best results?

SDN: Unshackling the Network Application Environment

What will be the killer app for SDN, and does there have to be only one?

An SDN for Every Market

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.

Looking Past SDN to the Cloud

Technologies like the software defined network evolve within the confines of wide industry trends. These days, that would be the cloud.

Visibility and SDN: You Can't Manage What You Can't See

SDN's flexible, dynamic nature creates new network monitoring and visibility problems. Here's what networking vendors are doing to solve those problems.

Hardware Customization in a Software-Driven Universe

Programmability will bring unprecedented flexibility to the software defined network, but what about customizing the underlying hardware?

Networking in a Changing Data Environment

Just as networks take their first steps into virtual infrastructure, the data environment and its requirements are changing again.

Networking, Private Cloud, and the Heterogeneous Environment

Some networking vendors aim to unify multi-vendor, legacy data center silos into the interoperable environments private cloud requires.

SDN Makes VDI a TCO Game-Changer

Network virtualization and SDN are finally making VDI viable for the enterprise. Art Cole discusses where it will work best.

Working Toward the Wide Area LAN

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.

First SDN, Then the Intelligent Network

What are the practical benefits of intelligent networks, and how does network intelligence differ from SDN?

What's Holding Data Center Performance Back?

Data center spending often focuses on performance improvements. But what are the real culprits behind poor performance, and how can you fix it?

SDN: It’s All About the Apps

SDN application development efforts look set to increase the capabilities and value of software defined networks in the enterprise.

SDN: A Study in Action and Reaction

The enterprise isn't yet equipped to deal with the consequences of SDN, because no one knows what those consequences will be.

The Road to the Cloud Runs Through the Network

Advanced cloud architectures will require advanced network infrastructure in the data center.

Ethernet Faces High-Bandwidth Growing Pains

The road to 100 Gbps+ Ethernet is proving more complicated than it first appeared, at least for those considering hyperscale deployments.

SDN Automation: Not as Simple as You Might Think

Automation and SDN seem to go hand in hand, but several challenges still need to be solved before automation is automatic in software defined networks.

Should the Fabric Have a Core? Perhaps for a Little Longer

Network fabrics imply a flattened architecture that eschews centralized switching. So why are vendors still talking about core fabric switches?
