Use an SDN controller with IBM solutions to secure your assets in the cloud

In the first post of a series on developerWorks, my colleague and I discussed how to manually deploy the flow rules for Open vSwitch to protect virtual machines (VMs) running on a KVM hypervisor. However, the solution we proposed then is not always practical in the real world, because the assets in the cloud can […]

Intel’s Billy Cox on the unprecedented awesomeness of disruption

When I gave the keynote at Open Compute Platform (OCP) European Summit this past October, I talked about disruptive technologies. As anyone reading this blog knows quite well, our industry moves very quickly, constantly bringing new disruptions to market. That’s a given—and a good thing. In this case, what was disruptive five months ago is […]

Docker offers big opportunity for software-defined networking

By Rakesh Saha and Jay Kidambi Recently, technologies like Docker have popularized software containers as basic computational units for application deployment. In addition to easing the process of application development, testing, deployment and maintenance, these technologies also promise to be lighter-weight alternatives to full-fledged virtualization. In most environments, containers will coexist with other computational units […]

What is software-defined networking?

Many people have heard the term “software-defined networking,” or SDN. Fewer people understand, in practical terms, what SDN can do for them. In this post, I provide a brief introduction to SDN and describe what it can do for you in the cloud. Perhaps the key advantage of the cloud is that is allows you […]

Dive into the software-defined network ocean with OpenStack

By John M. Tracey and Ramesh Menon One area where the cloud can be particularly useful is in simplifying the traditionally onerous process of provisioning and configuring network infrastructure and services. Many people wonder though how they can begin to utilize the cloud for networking. In this post, we describe an easy way to get started […]

Dinosaurs and the cloud: The mainframe’s role

Dinosaurs are not usually something you equate with cloud computing, but bear with me while using this analogy. Around 20 years ago I had my summer internship in the internal IT department at IBM in Norway, and I can still remember a poster that hung on the one of the office doors. It said “The […]

Securing Software Defined Networking: Using open standards with IBM solutions to secure your assets in the cloud

Software Defined Networking (SDN) is an emerging technology that has come in tandem with the rise of cloud computing. This prominent technology adds a boost to network virtualization, which eliminates the boundary of the physical network topology. However, the dynamic nature of SDN makes it harder to manage compared to a traditional network. When securing […]
