Through http://blog.ipspace.net I landed on this article on acm.org discussing the complexity of distributed systems. Through some good examples, George Neville-Neil makes it clear that creating and scaling distributed systems is very complex and “any one that tells you it is easy is either drunk or lying, and possibly both”. Networks are of course inherently distributed systems. Most everyone that has managed a good sized network before knows that like the example in the article, minor changes in traffic or connectivity can have huge implications on the overall performance of a network. In my time supporting some very large networks I have seen huge chain reactions of events based on what appear to be some minor issues. Very few networks are extensively modeled before they are implemented. Manufacturers of machines, cars and many other things go through extensive ... (more)

SDN and Gartner’s Hype Cycle By @MartenT1999 | @CloudExpo [#SDN]

Many years ago Gartner introduced their technology Hype Cycle, which maps visibility against maturity for new technology. The Hype Cycle in essence states that many new technologies get a large amount of visibility early in their maturity cycle. The visibility and enthusiasm drops significantly when reality sets in: technologies early in their maturity cycle will have low adoption rates. The vast majority of customers of technology are conservative in their choices, especially if this new technology is not (yet) fundamental to this customer’s business. I call it common sense rea...

The Next Network Transformation: We Have Only Just Begun By @MartenT1999

Whenever we get to the end of a year we have this tendency to reflect on what has happened in the past year and how we can improve in the coming year. It’s natural to use the change of calendar year as a point in time to think back, even though practically speaking it is usually the most chaotic time of the year between shopping, family and year and quarter end at work. Almost every industry will go through waves of change and transformation. Real change and transformation is driven by powerful market forces of demand coupled with technology leaps that allow an escape from increme... (more)

Pay Attention to Big Data By @MartenT1999 | @BigDataExpo [#BigData]

Network Engineers, Pay Attention to Big Data You have probably realized we are having a Big Data kind of week here at the Plexxi blog. And for good reason. The amount of development and change in this big bucket of applications we conveniently label “Big Data”, is astonishing. Walking around at Hadoopworld in New York last week, I initially felt somewhat lost as a “networking guy”. But that feeling of “not belonging” is only superficial, the network has a tremendously important role in these applications. The challenge is that many “networking” folks don’t quite understand or r... (more)

Training Wheels and Protective Gear By @PlexxiInc | @CloudExpo [#SDN]

Throughout the development cycle of new features and functions for any network platform (or probably most other products not targeted at the mass market consumer) this one question will always come up: should we protect the user of our product from doing this? And “this” is always something that would allow the user of the product to really mess things up if not done right. As a product management organization you almost have to take a philosophical stand when it comes to these questions. Protect the user Sure enough, the question came up last week as part of the development of on... (more)
