Video: The Network Is Not Reliable

After introducing the fallacies of distributed computing in the How Networks Really Work webinar, I focused on the first one: the network is (not) reliable.

While that might be understood by most networking professionals (and ignored by many developers), here’s an interesting shocker: even TCP is not always reliable (see also: Joel Spolsky’s take on Leaky Abstractions).

What Content is Missing?

Prior to my current job, I enjoyed the time I invested in the community. I spent quite a bit of time on The Cisco Learning Network helping those that were early in career. I also blogged here regularly (typically weekly) and spent time in the Twitterverse and on Slack. From this perspective, taking a job with a vendor was more different than I expected. It was like someone flipped a switch and I was completely spent at the end of each and every day.

On a few occasions, I have tried to get back what I would have previously considered some level of normalcy with regards to the community. I have decided that this year is my year to make some major changes. I must do a better job prioritizing things I care about and realize that some [read many] things just aren’t going to get done. That is one thing I’ve learned over the past few years. Even though I have always felt that my workload was significant, there is nothing like having a job in which you can only get a small portion of the overall work completed. It just doesn’t feel good.

The community and the relationships Continue reading

How to Manage a Home Network with Infrastructure as Code

Unifi Dream Machine home management device because, in addition to my personal and guest SSIDs, there is an apartment in my house for which I wanted to segment traffic. I also wanted to add an extra layer of security around some of the home automation and IoT devices that were being added to our home network with a fourth SSID. I started to configure the new network, I had started a spreadsheet of VLANs, subnet CIDRs and mappings of those to SSIDs. Additionally, I needed to track firewall rules, port forwards and other settings and configurations. Needless to say, this was a lot of information to maintain and manage. My day job is working on the Infrastructure-as Code (IaC) product

Our Favourite Picks from the KubeCon Europe 2020 Schedule

Last Wednesday, the CNCF released the KubeCon Europe 2020 schedule. There are so many talks at KubeCon it can be daunting even to decide what to go to see!

Simplify Your Cloud-Native Application Packaging and Deployments – Chris Crone

Chris is an engineer in our Paris office and is also co-executive director of the CNAB project. CNAB (Cloud Native Application Bundle) is a specification for bundling up cloud-native applications, which can consist of multiple containers, into a single object that can be pushed to a registry. Open source projects using CNAB, like Docker App or Porter allow you to package apps that would normally require multiple tools like Terraform, Helm, and shell to deploy, into a single tooling agnostic packaging format. These packages can then be shared using existing container registries and used with other CNAB compliant tools. This can really simplify cloud-native development.

How to Start Your Network Automation Journey

A journey of a thousand miles begins with one step they say… but what should that first step be if you want to start a network automation journey (and have no idea how to do it)?

Intel drops work on one of its AI-chip lines in favor of an other

Well, that was short.Intel is ending work on its Nervana neural network processors (NNP) in favor of an artificial intelligence line it gained in the recent $2 billion acquisition of Habana Labs.[Get regularly scheduled insights by signing up for Network World newsletters.] Intel acquired Nervana in 2016 and issued its first NNP chip one year later. After the $408 million acquisition by Intel, Nervana co-founder Naveen Rao was placed in charge of the AI platforms group, which is part of Intel's data platforms group. The Nervana chips were meant to compete with Nvidia GPUs in the AI inference training space, and Facebook worked with Intel “in close collaboration, sharing its technical insights,” according to former Intel CEO Brian Krzanich.To read this article in full, please click here

Game changers at the branch: Wi-Fi 6, 4G, 5G plus SD-WAN

Combining 4G and 5G cellular services with SD-WAN can give enterprise IT pros connectivity options that are faster than wired alternatives such as MPLS and that provide benefits including rapid provisioning, improved reliability and more bandwidth for less money.Branch offices, which are undergoing dramatic changes in the amount of traffic they generate and where that traffic goes, can particularly benefit from 4G and 5G, and one enabler is software-defined WAN.To read this article in full, please click here
