As we head through earnings season, we get the opportunity to learn a bit about the state of the networking industry. Each data point gives us a bit more information about how the competitive landscape is unfolding, and ultimately how this will shape the market. So what do we know so far?
Networking is a visual field. In fact, we can generalize and say all of IT is. Come to think of it, is there a technical field that isn’t? In this post, I’ll cover a handful of visualization tools that have recently helped me think through and communicate difficult Network Engineering stuff.
We’ve spent some cycles talking about user experience and workflow in previous articles. So in this post, we’re going to explore how these things relate to one another in the context of networking.
Virtualization, in conjunction with ADCs, can make a big difference for businesses, whether large or small.
Traditionally, just getting a network feature to work and inter-operate was the goal, but now we must consider how this feature fits into common workflows performed by network engineers.
In network engineering, the “T” is very long: Configuring a network to achieve business goals requires considerable skill and knowledge. In this post, we’ll explore this in a little more detail.
This week I read a perfectly reasonable article by Tom Hollingsworth, which then deteriorated in the comments section to a “you don’t know how a switch works” exchange.
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.
