Data-center training, recruitment need to change to meet staffing demand

As demand for data-center capacity has surged, owners and operators are struggling to keep pace on the employee side. Improved outreach, more creative approaches to recruitment, and better training and education opportunities are needed to ensure the data-centers can meet the "astronomical anticipated demand" for skilled people, said Rhonda Ascierto, vice president of research at Uptime Institute.The research firm's newly released Global Data Center Staffing Forecast reveals concern about the volume of open jobs and hard-to-find skills. In 2020, 50% of data-center owners and operators reported having difficulty finding qualified candidates for open jobs, compared to 38% in 2018. Meanwhile, demand for data-center staff is forecast to grow globally from about 2 million full-time employees in 2019 to nearly 2.3 million by 2025, Uptime Institute reports.To read this article in full, please click here

Link-State Routing Protocols Are Eventually Consistent

One of my readers sent me this interesting question:

Assuming we are running a very large OSPF area with a few thousand nodes. If we follow the chain reaction of OSPF LSA flooding while the network is converging at the same time, how would all routers come to know that they all now have same view of area link states and there are no further updates or convergence?

I have bad news: the design requirements for link state protocols effectively prevent that idea from ever working well.

Upgrading Firmware on Northbound Networks Zodiac FX

Recent versions of firmware (after v0.80) running on the Northbound Networks Zodiac FX can be updated directly from the web interface, or using XMODEM via the serial console. But what if, say, you had sat one your Zodiac FX for a while and are running firmware earlier than v0.81 and have a sudden, unexpected desire to upgrade the firmware? Say you are, for example, me?

The process turned out to be less straightforward than I had hoped, so I am documenting the successful steps I followed in case it’s of use to somebody else.

My (Brief) Zodiac FX Background

Back in 2015 I backed a Kickstarter project for this awesome-sounding four-port FastEthernet SDN switch with OpenFlow support. It sounded so cool that I even ordered a two-pack as I thought it would be more fun to have two OpenFlow switches to mess around with). The project was funded successfully, but embarrassingly when the beautifully-made boards arrived in early 2016, for some reason I never quite got around to playing with them. I think it was in part because it was just a printed circuit board without a case and without easy access to 3D printing I was turned Continue reading

Heavy Networking 562: Juniper’s Paragon Automation Portfolio Prioritizes Service Experience (Sponsored)

In today’s sponsored show with Juniper Networks, we dive into Juniper's Paragon product portfolio, which measures service quality for critical applications. The portfolio allows service providers and enterprises to get deeper visibility into, and automated control over, their networks.

SEC 3. Building your own containerised PKI (root CA) with Linux and Docker to simplify and secure network automation

Hello my friend,

You know our passion to network automation. We truly believe, that this is the only sustainable way for the network development and operation. In the same time, one the key goals of the automation is to make your network secure and safe. Therefore, the security of the automation and communication channels used by automation is very important. So today we’ll take a look how to build

Can automation make your network better?

Automation is the key component of the perpetual engine of your network development and operation. It allows you to run the network quick, stable, and safe. And we are willing you to benefit as much as you can from that.

We have created a new training, which is focused only on the Nornir and you can use it for the network (and not only) automation. It is an organic extension of our network automation training, which assumes you are already Continue reading

Smart ways to compare files on Linux

Commands for comparing files have proliferated since the early days of Linux. In this post, we'll look at a suite of commands available for comparing files and highlight the advantages that some of the newer ones provide.diff One of the oldest and still popular commands for detecting and reporting on file differences is the diff command. Comparing two lists of meeting attendees, the diff command will simply and clearly show you the differences.$ diff attendance-2020 attendance-2021 10,12c10 < Monroe Landry < Jonathon Moody < Donnell Moore --- > Sandra Henry-Stocker Only the lines that are different are displayed.

On the ‘net: The Art of Conviction

I was recently a guest on The Art of Conviction podcast, where we covered a bit of my background, some of the challenges I’ve faced in getting where I am, and then we moved into a discussion around my recently finished dissertation. I’m working to find places to publish more in the area of worldview and culture; I’ll point to those here as I can find a “home” for that side of my life.

You can find the recording here.

Beyond my episode, The Art of Conviction is a fascinating podcast; you should really subscribe and listen in.
