As SDN gains traction within the private sector we are also seeing federal agencies adopt it as they identify the need for network infrastructure changes.
Just when you got used to ethernet speeds being a nice decimal based system where we simply add zeros every few years, someone threw in 40GbE a few years ago. And that’s ok, powers of two we can deal with, but 25?
Whenever a new networking platform is evaluated, one of the early sales calls includes a packet walkthrough. But why?
Much has been published about the Open Compute Project. Initiated by Facebook, it has become an industry effort focused on standardization of many parts and components in the datacenter. It’s not a huge innovative leap, but it’s a significant convenience.
Most people in the IT space understand the trend towards bare metal everything (servers, switches, etc.). The movement to commodity hardware drives down costs in infrastructure where price is disproportionately determined by the cost of hardware.
Why can’t companies adapt to change? The ideal sector to see disruptive innovation at work is the technology sector. Many billions are spend on bringing products to market that fail.
As connectivity becomes more and more a commodity service and requirements become more demanding, how that connectivity is provided has to evolve.
These items are a combination of tech business news, development news and programming tools and techniques.
How much of history do we retain from written accounts? If we don’t write history down, it doesn't happen—now we generate reality partially through online publishing.
There is no question that many of our applications will move to the cloud. Pure economics will drive that. But at the same time there will continue to be resistance for a long time to come to move certain applications and data into the cloud.
As a self-taught programmer, the most inspirational book for me in my early years, what really made me want to be a coder and never look back, was Steven Levy’s Hackers: Heroes of the Computer Revolution.
While the bulk of the networking industry’s focus is on CapEx and automation, the two major trends driving changes in these areas will have a potentially greater impact on that which matters most: availability.
Architects and operators should ask this question to see what kinds of answers come back. An honest answer should lead to follow-on questions.
We are collectively making the step into network based storage. We should also make the step to run this effectively with maximum performance and minimal interference on a single network. It really can be pretty simple…
If networking really is on the cusp of changing over, user experience has to be an input into the design process. This is a radical change in how products are conceived, built, and ultimately brought to market.
5 smart programmers can bring down a whole multi-billion industry and change people's habits.
Software Defined Networking (SDN) has quickly spawned what appears in some respects to be a cottage industry of would-be disruptors to the more traditional networking approaches.
I led a session about improving our writing skills. I wanted to gather more ideas to supplement my talk and my article on "Writing an Excellent Programming Blog". A half-dozen smart people showed up with tips and links. Here are my notes.
I want you to write. Not just code. Also words. If you're a member of the open source community, you can help us by writing about programming, just as much as by actually programming. And writing helps you, too: you can become better known and promote your ideas. Even more importantly, writing is thinking. There is no more thorough way to understand than to explain in writing.
It is mostly accepted that configuration deals with the deployment of devices and applications within an infrastructure.
Friction in any ecosystem is greatest at the boundaries between elements. When two things must work together to perform a task, the act of coordinating comes with some overhead.
None of us should be surprised when the industry starts talking a bit more broadly about the role of the operating system going forward.
If nothing else, SDN in whatever definition you like, is giving us the concept of a programmable network. And what use is programming a network if all you use it for is to automate basic configuration information?
When people talk about pricing and switch sizes today, answers are usually framed up in some derivative of the per-port discussion
