We recently completed a survey on the impact and drivers of network complexity (detailed results can be found here where 80% of IT pros, based in the UK, indicated that increasing network complexity had impacted their role within the last three to five years. To any IT pro this is nothing new, but the top drivers of this network complexity, might catch a few by surprise.


We broke the drivers into three categories:

  • Technology
  • IT Operations
  • Business Operations





Within technology the top two drivers were compute virtualisation and smarter/more complex equipment. The third most popular which fell somewhat significantly behind the first two was video conferencing/telepresence. To me equipment complexity is interesting, it feels contradictory to the value proposition of smarter equipment – isn’t that supposed to make your life less complex, and save you time and money?  Perhaps the savings in hardware are being consumed by software and manpower costs required to manage the more complex gear.  Software Defined Networks (SDN) – the fourth most popular - was also an interesting trend given how early in the deployment cycle we are, it seems that many folks are projecting how they think complexity will be impacted by SDN.





On the IT operations side I was surprised that BYOD and mobility ranked #1 and #2 for adding complexity to the delivery of IT services.  The ubiquity of mobile devices and the rate at which they’ve penetrated the work environment is amazing and likely caught many IT organisations off guard. Of course when the driver for a new IT service like mobility is senior management it’s tough to say no, so many folks charge forward and figure out the operational details after the fact.





Finally from a business operations standpoint security is the standout complexity driver.  From day zero threats to SIEM, there’s no shortage of new things being added to the IT plate – and in case you didn’t know, security is every IT Pro and businesses’ concern, not just the security team!





By now you’re probably feeling a bit overwhelmed and understaffed, and it’s no surprise.  What is surprising is that the number one skill that is needed to address the challenges of network complexity is ‘understanding the business’, identified by nearly one-third of UK IT pros.  The context that business knowledge provides in making the right decisions is remarkable.  Throw all the technology at you that the industry can muster, but if you understand the business needs you can cut through the hype and predicted benefits and get down to brass tacks.  Shortly behind the business understanding is network engineering, and information security – in our connected world those responses that make a lot of sense.


So how to get at these skills? Training of course. But it seems that your management still doesn’t understand the value of training as budget and time were the top two barriers to getting the help you needed. This is a continuing trend, at a time when management will spend hundreds of thousands of pounds on hardware and software, spending the time and money to get trained right seems to require a two-thirds majority in congress.


So there you have it – the state of network complexity in 2013 – change is inevitable in the IT space and getting the training and development to stay ahead of the game is critical.

When I first started working in I.T., my toolbox was pretty thin. Actually, so were the MSDOS PCs that I was working on, so it didn't take a lot of tools to manage an 8086PC. My entire toolset fit on a single 360kb floppy disk. Life in I.T. has changed dramatically since that long-ago time, and today the toolbox of the ITPro is an indispensable thing. Also, to a great extent, that toolbox is no longer something we carry around with us, but rather capabilities and services that make doing what we do so much easier.


Recently I was asked to identify the Top 10 innovations that changed my life in I.T. I solicited a bit of help from some friends, and this is the list we came up with:
