A quote from an Ex-Googler

I really like this paragraph, because almost everyone wants to imitate google. Why? well, the answer to that questions seems to be what everyone is missing!

Google’s solutions were built for scale that basically doesn’t exist outside of a maybe a handful of companies with a trillion dollar valuation. It’s foolish to assume that their solutions are better. They’re just more scalable. But they are actually very feature-poor. There’s a tradeoff there. We should not be imitating what Google did without thinking about why they did it. Sometimes the “whys” will apply to us, sometimes they won’t

The quote comes from Cloud Field Day 4, from Ben Sigelman of LightStep.

Network Automation with Ansible for Undergraduate Students

Last year’s experiment generated so much interest that I decided to repeat it this year: if you’re an undergraduate or Master's student and manage to persuade us that you’re motivated enough to automate the **** out of everything, you’ll get a free seat in Ansible for Networking Engineers online course.

Interested? Check out the details, and apply before October 1st.

Too old? Please spread the word ;)

Starting a new series: AWS ABCs

I'd be lying if I said that since starting my new job at Amazon Web Services (AWS), I wasn't looking forward to writing about all the new things I was going to learn. Obviously there's the technology and services that make up the platform itself. But there's also the architectural best practices, the design patterns, and answers to questions like “how does moving to the cloud improve my performance/security/reliability?” Admittedly, I have a lot to learn.

AWS ABCs — Logging Into a New EC2 Instance

Ok, you've just launched an Amazon EC2 instance (ie, a virtual machine) and you're ready to login and get to work. Just once teeeensy problem though… you have no idea how to actually connect to the instance!

This post will walk through how to log into brand new Linux/BSD and Windows instances (the steps are slightly different for different OS families).

California’s bad IoT law

California has passed an IoT security bill, awaiting the governor's signature/veto. It’s a typically bad bill based on a superficial understanding of cybersecurity/hacking that will do little improve security, while doing a lot to impose costs and harm innovation.


It’s based on the misconception of adding security features. It’s like dieting, where people insist you should eat more kale, which does little to address the problem you are pigging out on potato chips. The key to dieting is not eating more but eating less. The same is true of cybersecurity, where the point is not to add “security features” but to remove “insecure features”. For IoT devices, that means removing listening ports and cross-site/injection issues in web management. Adding features is typical “magic pill” or “silver bullet” thinking that we spend much of our time in infosec fighting against.

We don’t want arbitrary features like firewall and anti-virus added to these products. It’ll just increase the attack surface making things worse. The one possible exception to this is “patchability”: some IoT devices can’t be patched, and that is a problem. But even here, it’s complicated. Even if IoT devices are patchable in theory there is no guarantee vendors will Continue reading

IDG Contributor Network: Migrating to the cloud Is a good start, but what you do next is critical

Today, it seems like every business is migrating to the cloud. And it’s true – nearly three in four businesses are using cloud solutions to augment traditional networking practices, with no signs of slowing down. The cloud’s potential has captured the attention of business leaders across nearly every industry, thanks to its promise of speed, scale and control. In fact, nine out of ten companies rely on the cloud to accelerate digital transformation and drive business growth.To read this article in full, please click here

Think Like an Engineer, not a Cheerleader

When you see a chart like this—

—you probably think if I were staking my career on technologies, I would want to jump from the older technology to the new just at the point where that adoption curve starts to really drive upward.

Over at ACM Queue, Peter J. Denning has an article up on just this topic. He argues that if you understand the cost curve and tipping point of any technology, you can predict—with some level of accuracy—the point at which the adoption s-curve is going to begin its exponential growth phase.

Going back many years, I recognize this s-curve. It was used for FDDI, ATM, Banyan Vines, Novell Netware, and just about every new technology that has ever entered the market.

TL;DR
  • There are technology jump points where an entire market will move from one technology to another
  • From a career perspective, it is sometimes wise to jump to a new technology when at the early stages of such a jump
  • However, there are risks invovled, such as hidden costs that prevent the jump from occurring
  • Hence, you need to be cautious and thoughtful when considering jumping to a new technology

 

The problem with this curve, Continue reading

IDG Contributor Network: IoT alphabet soup: when should an enterprise use MQTT versus LWM2M?

There is tremendous interest from industrial enterprises to understand the nuances of the two most debated IoT data communications protocols: MQTT and LWM2M. MQTT and LWM2M are protocols that create a standard way to get device data to systems, platforms, applications, and other devices.Let’s talk a little about each protocol and when it’s best used in an enterprise IoT deployment.MQTT and when to use it Message queuing telemetry transport (MQTT) is an ISO standard which describes a publish/subscribe (pub/sub) messaging protocol. Nearly all IoT platforms support MQTT communication, making it the de facto standard for device-to-platform IoT communication.To read this article in full, please click here
