Formalisation of Automation: WIP

For the last five or six years, I’ve not really done any networking and have focussed on software, automation and the mechanisation of processes so that they may be manifested as network driving workflows. I try to keep up with networking technology and working for Juniper has really made me level up in this aspect. I’m lucky to be surrounded by an army of real experts and it’s humbling. What’s still a thorn in my side is the beginner expert community around automation, and I’m working to bring awareness to this through providing questions and insight with methodologies to bootstrap the journey. More on that another time. This paragraph is to position some emotions for what’s about to follow!

To get to the crux of this post, now shift your view to your every day life. How many times a day does an app crash on your phone, laptop or tablet? When was the last time a feature wasn’t available on your TV because you didn’t upgrade to the latest version of software? Right at the beginning of my career, I worked in real time electronics. Machinery that should not die randomly, or just become obsolete because of the hardware Continue reading

Bringing Cloud Principles to The Enterprise

JU-CV-2019-Blog

As legacy applications evolveto the cloud, hosted and multi cloud architectures blending on-premises data and applications with elastic scale-out and rapidly deployed cloud capabilities, legacy networking tools have been challenged causing them to become cumbersome and unreliable. The shift to cloud native architectures with containers, serverless instances and edge IoT sensors feeding in critical data, has significantly increased the number of devices that need to be managed. Meanwhile shrinking the amount of time available for provisioning, upgrades and change controls has become an issue. 

10 things you need to know about MU-MIMO Wi-Fi

Multi-user MIMO allows multiple Wi-Fi devices to simultaneously receive multiple data streams. For example, a wireless access point (AP) can send data to four different Wi-Fi devices at the same time. MU-MIMO can greatly increase the network's throughput and is a real asset for high density networks.If you aren’t familiar, MIMO stands for multiple input multiple output. The technology has evolved over the years since the debut of the single-user mode (SU-MIMO), which was introduced a decade ago with the 802.11n wireless standard.To read this article in full, please click here

Beware the Marketing Magic of GUI-Based Programming

Someone working for a network automation startup desperately tried to persuade me how cool their product is. Here’s what he sent me:

We let network engineers build their own network automation solutions in no time without requiring coding or scripting knowledge. It’s all GUI based, specifically geared towards network engineers - they can simply model services or roll-out networks “as-designed”.

The only problem: I’ve seen that same argument numerous times…

Managing High Availability in PostgreSQL – Part III: Patroni

Managing High Availability in PostgreSQL – Part III: Patroni - ScaleGrid Blog

In our previous blog posts, we discussed the capabilities and functioning of PostgreSQL Automatic Failover (PAF) by Cluster Labs and Replication Manager (repmgr) by 2ndQuadrant. In the final post of this series, we will review the last solution, Patroni by Zalando, and compare all three at the end so you can determine which high availability framework is best for your PostgreSQL hosting deployment.

Wow: NVMe and PCIe Gen 4

Recently it’d come to my attention that my old PC rig wasn’t cutting it.

Considering it was 10 years old, it was doing really well. I mean, I went from HDD to 500 GB SSD to 1 TB SSD, up’d the RAM, and replaced the GPU at least once. But still, it was a 4-core system (8 threads) and it had performed admirably.

The Intel NIC was needed because the built-in ASUS Realtek NIC was a piece of crap, only able to push about 90 MB/s. The Intel NIC was able to push 120 MB/s (close to the theoretical max for 1 Gigabit which is 125 MB/s).

The thing that broke the camel’s back, however, was video. Specifically 4K video. I’ve been doing video edits and so forth in 1080p, but moving to 4K and the power of Premerier Pro (as opposed to iMovie) was just killing my system. 1080p was a Continue reading

3 strategies to simplify complex networks

As the cloud era meets the demands of digital transformation, networks must change. That means for enterprises, they must become simpler, said Juniper CEO Rami Rahim, speaking at the company's annual industry analyst conference last week.The past five years has seen more innovation in networking than in the previous 30. Things such as SD-WAN, multi-cloud, Wi-Fi 6, 5G, 400 Gig, and edge computing are on the near-term horizon for almost every company. While all of those technologies have enabled the network to do so much more than ever before, their complexity has also risen.To read this article in full, please click here

How to freeze and lock your Linux system (and why you would want to)

How you freeze and "thaw out" a screen on a Linux system depends a lot on what you mean by these terms. Sometimes “freezing a screen” might mean freezing a terminal window so that activity within that window comes to a halt. Sometimes it means locking your screen so that no one can walk up to your system when you're fetching another cup of coffee and type commands on your behalf.In this post, we'll examine how you can use and control these actions. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] How to freeze a terminal window on Linux You can freeze a terminal window on a Linux system by typing Ctrl+S (hold control key and press "s"). Think of the "s" as meaning "start the freeze". If you continue typing commands after doing this, you won't see the commands you type or the output you would expect to see. In fact, the commands will pile up in a queue and will be run only when you reverse the freeze by typing Ctrl+Q. Think of this as "quit the freeze".To read this article in full, please click Continue reading

The Week in Internet News: Antitrust Investigations of Big Tech Heat Up

Playing monopoly: Antitrust investigations of large U.S. tech companies are launching, with 48 state attorneys general announcing a Google probe, Salon.com reports. The focus is on Google’s alleged domination of online advertising.

Broadband Island: Anacortes, Washington, on Fidalgo Island near Seattle, is building its own broadband network, Geekwire.com notes. The city is using existing water lines to install fiber optic cable, and the service will cost residential customers $39 per month for 100 Mbps service and $69 for gigabit speeds. 

The Internet of Gasoline: Hackers are increasingly talking about ways to target Internet of Things connected gasoline pumps, ZDNet reports.
