What makes the cloud such an attractive option for enterprises? The cloud empowers IT to act as a broker of business critical IT services. It helps the organization become a more proactive player that can aggregate, integrate, and customize the delivery of cloud services to meet specific business needs. Instead of working in a technology vacuum or owning the entire IT value chain, IT can make build or buy decisions in the context of IT services sourcing recommendations.
Businesses in every industry are rapidly embracing the cloud. They want the agility, security, and performance that cloud technology delivers. And they want the flexibility to deploy their choice of workloads securely to the cloud. This growing demand for cloud services is creating new opportunities for cloud providers and driving new job roles and responsibilities.

Happy with how you go about learning, or wish you could learn more, learn more quickly, and even just do it? Today’s post continues what was begun in the previous post, namely a list of good practices to consider to improve how you go about learning throughout your IT career.
The previous post set up the issues, and made two broad suggestions:
- Continuously learn more about learning and study, practice what you learn, and improve
- Research and improve note-taking skills for each type of notes you take
Today’s post adds two more practices to the list, with a renewed request that you add your suggestions as well. Today, we’ll examine one type of short-term tactical goal setting with SMART goals, plus a much-neglected study activity: thinking about what you already studied.
3) Start Each Week w/ Achievable SMART Goals
Have you ever finished a week with this thought?
“I failed to make as much progress as I would have liked to make with what I’m learning right now.”
Many factors, both controllable and uncontrollable, affect whether we meet our goals. This next practice helps us achieve our short-term goals by setting and reviewing SMART learning goals weekly, every week.

The debate of what we should be learning seems to be a more frequent topic today. For instance, there’s been a long-standing question for each new networker: after learning a little about routing and switching, does a relative newbie dive deep into route/switch? Move on to learn voice? Or security? Data Center? Or for emerging technologies like SDN, should we learn SDN as defined by the Open Networking Foundation, or ACI, or both? Should we build programming skills to become network programmers, or programming for network automation, or stick with traditional config/verify/troubleshooting skills?
So we can talk to coworkers and discuss/argue about what technologies we should learn… but then we all seem to agree that learning throughout our careers is hugely important. (In fact, the day I was wrapping up this blog post, the Cisco Champion podcast included several people making that very same point, in agreement.) And then we stop talking about learning, because we all agree. We agree that learning is important, and don’t talk about how to learn effectively.
Our long-term career prospects depend in part on learning about existing and emerging technology. But how good are our learning skills? Are we happy with the results? How can we get better at learning?
Today’s post begins a 2-part post that offers a top 4+1 list of answering that last question: how do we get better at learning? Rather than us just agreeing that learning is important, and moving on, let’s treat the process of learning as an important process, and learn how to do it better. Read More »

When I started with my first Cisco router back in 1995, I never would have imagined I would someday be the technology lead for an ice arena of an NHL team. I also would never have predicted the impact that having a Cisco certification would have on being recruited to that position.
Most of my career up until now was spent working in the small and medium business space, primarily on ISP and telecom space working with voice and networks with some software and infrastructure design in the middle. Cisco was a large part of everything that I did from routing and switching to voice over frame relay followed by voice over IP, with a large emphasis on small bandwidth efficiency and signalling. I’m even the lead inventor on an issued patent relating to intelligent rerouting of fax traffic on VoIP systems.
I never thought much about certifications. I have a BA in Economics which has served me well as a business owner and largely found all my work via word of mouth. There were not a lot of people who understood VoIP payload and signalling tuning, starting from the MC3810 and up through the as5300/as5800 series. This was primarily in international carrier / wholesale VoIP traffic and engineering.
As VoIP became more of a commodity good and the cost of equipment came down, this market dried up. In hindsight, I should have paid more attention to Cisco exiting that market, which proved to be a good decision. As my clients and partners moved on to other ventures and I was forced to begin prospecting.
Suddenly, here I was with 30 years since I’d written my first program and roughly 20 years of internet and Cisco experience and I was struggling. I had a lot of experience, but didn’t have a portfolio of work that included any big names, mostly small businesses that no one had heard of. I needed a way to give new clients the confidence to call me. I knew that once I started the conversation, I could close the deal. Before that, however, I needed to actually get that call or email.

In my last blog on 5 GHz spectrum, I discussed the recent FCC ruling that permitted outdoor access points to use the U-NII 1 band (5150-5250 MHz).
But the story doesn’t stop there. As mentioned last time, there are significant technical challenges to using the 5 GHz band. It is not cleared spectrum. It contains incumbent uses that are important for national security and public safety. Therefore, it is imperative that Wi-Fi not create harmful interference to these incumbent systems. Cisco will not settle for less.
On the topic of interference, a particularly interesting component of the same FCC ruling that opened the U-NII1 band for outdoor AP’s is that it also re-opened the Terminal Doppler Weather Radar (TDWR) band (channels 120, 124, 128) with new test requirements for DFS protection. Hold on, let’s backtrack a bit before diving into what this means:
What is TDWR?
In brief, Terminal Doppler Weather Radar (TDWR) “is a Doppler weather radar system used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States.” TDWR uses the frequency band from 5600-5650 MHz which is why wireless network equipment needs to be proven to “do no harm” to TDWR. If you’re curious for more information on TDWR, then please click here and/or here.
A Brief History
Many of you reading this will recall that the FCC closed the use of the TDWR band several years ago as the result of numerous reports of wireless equipment creating interference with TDWR. Read More »
