Dell Joins AT&T to Further Develop Airship, Metal3-io, Ironic

Dell Technologies has joined with AT&T to collaborate on a number of open source technologies that the companies say will contribute to edge computing and 5G deployments, namely the Metal3-io (for Kubernetes) and Ryan Van Wyk, AT&T assistant vice president of network cloud software engineering at AT&T, in an interview with The New Stack. “The net effect is we’re helping to accelerate the deployment of open infrastructure that supports [software defined network] workloads. We see it as a flywheel effect in terms of making it easier for folks to deploy infrastructure and that makes it easier for them to grow their SDN ecosystem,” said Van Wyk. “Dell’s going to bring some focus to an area that’s core to their competency. When it comes to working on how to manage the RAID, the discs, the servers, the BIOS configurations, and validation of the hardware itself, and then integrate some of that stuff natively back into the Kubernetes Cluster API, those are things that are Continue reading

The First Networking Fundamentals Videos are Online

In mid-June I started another pet project - a series of webinars focused on networking fundamentals. In the first live session on June 18th we focused on identifying the challenges one has to solve when building an end-to-end networking solution, and the role of layered approach to networking.

Not surprisingly, we quickly went down the rabbit holes of computer networking history, including SCSI cables, serial connections and modems… but that’s where it all started, and some of the concepts developed at that time are still used today… oftentimes heavily morphed by recursive application of RFC 1925 Rule 11.

When private LTE is better than Wi-Fi

While cellular wireless is often thought of as a carrier service, IT organizations can benefit from deploying private LTE technology to complement or even replace Wi-Fi and for specific use cases such as supporting IoT devices that generate large data sets and that are spread out over large areas.To read this article in full, please click here(Insider Story)

VMworld 2019: Sneak Peak at Our Keynote Sessions. Plus a Chance to Win!

Networking & Security Keynotes at VMworld 2019

 

About a month ago, we published a VMworld security guide with shortlisted 100 to 300 level sessions that best illustrate real-world application of our products. This time, we’ll be focusing on two networking and security keynotes. The first keynote will highlight how VMware’s single-stack, complete networking and security platform can achieve a consistent operational network fabric for hybrid cloud environments, and the second keynote will focus on how users can leverage existing VMware infrastructure to implement a more effective, intrinsic security.

In addition, you will have a shot at winning Bose headphones simply by attending each event. Although chances are slim (1250 times harder to win both as opposed to just one), duplicate winners will be acknowledged so if you are looking for a present for yourself and a significant other, make sure to register and save on your yearly bonus! Winners will be announced at the end of each keynote, so make sure to stay until the end!

AWS ABCs: Granting A Third-Party Access to Your Account

There can be times when you're working on the AWS Cloud where you need to grant limited access to your account to a third-party. For example:

  • A contractor or a specialist needs to perform some work on your behalf
  • You're having AWS Professional Services or a partner from the Amazon Partner Network do some work in your account
  • You're conducting a pilot with AWS and you want your friendly neighborhood Solutions Architect to review something

In each of these cases you likely want to grant the permissions the third-party needs but no more. In other words, no granting of AdministratorAccess policies because it's easy and just works. Instead, adherence to the principle of least privilege.

This post will describe two methods—IAM users and IAM roles—for proving limited access to third-parties.

Live Preview: Build and Test Workers Faster with Wrangler CLI 1.2.0

Live Preview: Build and Test Workers Faster with Wrangler CLI 1.2.0

As part of my internship on the Workers Developer Experience team, I set out to polish the Wrangler CLI for Cloudflare Workers. If you're not familiar with Workers, the premise is quite simple: Write a bit of Javascript that takes in an HTTP request, does some processing, and spits out a response. The magic lies in where your Workers scripts run: on Cloudflare's edge network, which spans 193 cities in more than 90 countries. Workers can be used for nearly anything from configuring Cloudflare caching behavior to building entire serverless web applications. And, you don't have to worry about operations at all.

I was excited to focus on Wrangler, because Wrangler aims to make developing and publishing Workers projects a pleasant experience for everyone, whether you're a solo dev working on the next big thing, or an engineer at a Fortune 100 enterprise. The whole point of serverless is about reducing friction, and Wrangler reflects that ethos.

However, when I started at Cloudflare in early June, some parts of the development experience still needed some love. While working on a new WASM tutorial for the Workers documentation, I noticed a storm brewing in my browser…

Migrating ipSpace.net Infrastructure to AWS

I’m too stupid to unwind and relax over summer - there’s always some janitorial task to be done, and I simply cannot leave it alone. This summer, I decided to migrate our server infrastructure to AWS.

TL&DR: It went smoother than I expected, and figuring out how AWS virtual networks, public IP addresses, and security groups work while creating AWS Networking webinar definitely helped, but it also took way longer than I expected.

Netlify Migration

This blog is now hosted via Netlify, rather than GitHub Pages. It is still built using Jekyll, but I updated the theme to Mediumish.

I looked at switching to Hugo for site generation, but I hit several bugs trying to do the import, and theme setup was a pain. So I stuck with Jekyll, because it’s doing what I need. Using Netlify gives me a few more options around build and deploy, and moves away from Cloudflare.

All URLs and RSS feed should remain the same. Let me know if you see any issues.

Fast Friday – Mobility Field Day 4

This week’s post is running behind because I’m out in San Jose enjoying great discussions from Mobility Field Day 4. This event is bringing a lot of great discussion to the community to get everyone excited for current and future wireless technologies. Some quick thoughts here with more ideas to come soon.

  • Analytics is becoming a huge driver for deployments. The more data you can gather, the better everything can be. When you start to include IoT as a part of the field you can see why all those analytics matter. You need to invest in a lot of CPU horsepower to make it all work the way you want. Which is also driving lots of people to build in the cloud to have access to what they need on-demand from an infrastructure side of things.
  • Spectrum is a huge problem and source of potential for wireless. You have to have access to spectrum to make everything work. 2.4 GHz is pretty crowded and getting worse with IoT. 5 GHz is getting crowded as well, especially with LAA being used. And the opening of the 6 GHz spectrum could be held up in political concerns. Are there new investigations Continue reading
