Extreme targets SD-WAN services with Ipanema buy

With an eye toward reinforcing its cloud management business, Extreme Networks said it will acquire Ipanema’s SD-WAN business for about $73 million in cash.Ipanema and its SD-WAN business has been owned by France-based network orchestration firm Infovista since 2015 and has approximately 400 customers, mostly in Europe. Its cloud-managed SD-WAN platform is designed to deliver different workloads and applications securely across conventional wide-area networks and multicloud service providers, according to the company.To read this article in full, please click here

Using the Linux cut command to grab portions of lines from files

One surprisingly easy command for grabbing a portion of every line in a text file on a Linux system is cut. It works something like awk in that it allows you to select only what you want to see from files, enabling you to pull fields (regardless of the delimiter used), characters or bytes. To check on cut, you can ask about its version like this:$ cut --version cut (GNU coreutils) 8.32 Copyright (C) 2020 Free Software Foundation, Inc.

Selecting by field To illustrate how the cut command works, we'll first run commands using a sample "cities" file that contains details of the largest cities in the US in a tab-separated format.

The ‘Itanic’—Intel’s ill-fated Itanium processor—finally sinks

After two decades of failure and endless jokes, the Intel Itanium is officially no more. Intel has finally stopped shipping its doomed-from-the-start 64-bit processor, two years after saying it would cease shipments.Really, the end came some time ago. The last Itaniums were the 9000 series “Kittson,” which shipped in 2017. It’s a bane of technology firms to support technologies they would much rather ditch but can't due to customer investment, and for years Intel was obligated to support the paltry market that existed for Itanium.To read this article in full, please click here

ZeroLB, a New Decentralized Pattern for Load Balancing

Marco Palladino Marco Palladino is an inventor, software developer and internet entrepreneur based in San Francisco. As the CTO and co-founder of Kong, he is Kong’s co-author, responsible for the design and delivery of the company’s products, while also providing technical thought leadership around APIs and microservices within both Kong and the external software community. Prior to Kong, Marco co-founded Mashape in 2010, which became the largest API marketplace and was acquired by RapidAPI in 2017. With advancements in technology-driven by the Kubernetes — new architectural patterns have emerged to provide decentralized load balancing, yet portable across various platforms and clouds. The old monolithic and centralized load balancer, a technology largely stuck in the early 2000s, becomes deprecated in this new distributed world. The most common breed of load balancers being deployed across every application — centralized load balancers — are a legacy technology. They don’t work well in our new distributed and decentralized world. Remnants of a monolithic legacy way of doing things that did not adapt to modern best practices, centralized load balancers prevent users and organizations from effectively transitioning to the cloud Continue reading

The Grass is Always Greener

This last week I was talking to someone at a small startup that intends to eliminate all the complex routing from campus networks. In the past, when reading blog posts about Kubernetes, I’ve read about how it was designed to eliminate routing protocols because “routing protocols are so complex.”

Color me skeptical.

There are two reasons for complexity in a design. The first is you’re solving a hard problem. The second is you’ve made bad design choices in the past, and you’re pasting complexity on top to solve some perceived problem (whether perceived or real).

The problem with all this talk about building something that’s “less complex” is people tend to see complexity of the first kind and think, “we can get rid of that complexity if we start over.” Failing to understand the past before building the future is a recipe for repeated failures of the same kind. Building a network without a distributed routing protocol hasn’t been tried before either, right? Well, yes, it has … We either forget how it turned out, or we say “well, that’s not the same thing I’m talking about here” (just like “real socialism hasn’t ever been tried”).

Even worse, Continue reading

Dynamic DNS Security Blues

Whenever you run into a network problem, the wise network admin or sysadmin always remembers “It’s always Black Hat USA 2021 security conference Ami Luttwak and head of research simple loophole that allowed them to intercept dynamic DNS (DDNS) traffic going through managed DNS providers like Amazon and Google. And, yes, that includes the DDNS you’re using on your cloud. And, if you think that’s bad, just wait until you see just how trivial this attack is. Our intrepid researchers found that “simply registering certain ‘special’ domains, specifically the name of the name server itself, has unexpected consequences on all other customers using the name server.

The Challenge – And Opportunity – Of Being A Niche AI Cloud

In this era of hyperscaler and cloud builder titans, their seven of whom account for about half of the IT infrastructure bought in the world, it is important to remember the importance of niches and the vital role that other makers of systems, other sellers of systems, and other renters of systems all play in the IT ecosystem. …

HPC Efficiency Gurus Grapple with AMD’s RAPL

Exascale-class energy efficiency cannot be defined by a simple number. Although Green500 energy efficiency HPC rankings provide a one-shot view into performance/efficiency, the complex interplay between large system operating systems, real-world applications, and the various tuning capabilities is worth digging into. …
