Sample Network Automation Ansible Playbooks

I developed over a dozen different Ansible-based network automation solutions in the last two years for my network automation workshops and online course, and always published them on GitHub… but never built an index, or explained what they do, and why I decided to do things that way.

With the new my.ipSpace.net functionality I added for online courses I got the hooks I needed to make the first part happen:

What Is Steganographic Malware? New Type Of Attack Hides In Images

As defenses against standard cyberattacks evolve, so do the methods of attack carried out by malicious actors. Security researchers say a type of attack known as steganographic malware is on the rise. Gary Davis, the chief consumer security evangelist at cybersecurity firm McAfee, warned of the relatively new style of attack, which involves embedding secret …

Lenovo’s new workstation is indeed ‘Tiny’ but packs a punch

Windows users who work in tight spaces and looking for a small form factor workstation with multiple display ports and solid processing power have a new contender to check out: the new ThinkStation P320 Tiny.The workstation lives up to its name: At 1.4 x 7.1 by 7.2 inches, it's the smallest workstation on the market that is ISV (independent software vendor) certified, according to Rob Herman, the general manager of Lenovo's workstation business unit.The ISV certification is important. "We don't consider a machine to be a workstation unless it has ISV certification," according to Lloyd Cohen, an analyst with IDC.The U.S. government uses the same definition for workstations and for non-government users, software certifications mean that you can run CAD and CAM programs, for example, without worrying about crashing, Cohen noted. That's important if you're working on a complex design.To read this article in full or to leave a comment, please click here

IoT devices or humans?

A Swedish rail line can now collect fares by scanning its customers for embedded biometric chips. The primary benefit is the elimination of a physical ticket -- plus it’s harder to lose. It sounds futuristic, but my dogs have been sporting embedded chips for over a decade.If you think about it, physical tickets are kind of a silly. They are a surrogate for the person. The practice of scanning a ticket, instead of a person, was likely established when there just weren’t many viable alternatives. Technology now offers a more direct approach.To read this article in full or to leave a comment, please click here

Datanauts 089: SRE vs. Cloud Native vs. DevOps

SRE, or Site Reliability Engineer, is an effort to create a job role that puts operations teams on equal footing with developers. Rob Hirschfeld joins the Datanauts to discuss just what it means. The post Datanauts 089: SRE vs. Cloud Native vs. DevOps appeared first on Packet Pushers.

Worth Reading: Software is the future of optical

Flexible optical technologies like ROADMs, tunable wavelengths, and the newly enabled tunable modulation format high-speed optics along with sub-wavelength grooming via OTN (which is included in the transport SDN model) are just the beginning. As vendors allow more flexibility in their products, expect software developers to come up with even more ways to use the network as a platform for new services and new capabilities. —ECI

Cavium makes its ARM for data centers push with new servers

The initial efforts to bring ARM-based processors in the data center were not terribly successful. Calxeda crashed and burned spectacularly after it bet on a 32-bit processor when the rest of the world had moved on to 64-bits. And HPE initially wanted to base its Project Moonshot servers on ARM but now uses Intel Xeon and AMD Opteron.That’s because the initial uses for ARM processors were low-performance applications, like basic LAMP stacks, file and print, and storage. Instead, one company has been quietly building momentum for high performance ARM processors, and it’s not Qualcomm.Cavium, a company steeped in MIPS-based embedded processors, is bringing its considerable experience and IP to the ARM processor with its ThunderX server ecosystem. ThunderX is the whole shootin’ match, an ARMv8-A 64-bit SoC plus motherboards, both single and dual socket. In addition to hardware, Cavium offers operating systems, development environments, tools, and applications.To read this article in full or to leave a comment, please click here

Reducing data among proposed techniques to speed-up computers

Future computer systems need to be significantly faster than the supercomputers around today, scientists believe. One reason is because analyzing complex problems properly, such as climate modeling, takes increasing work. Massive quantities of calculations, performed at high speed, and delivered in mistake-free data analysis is needed for the fresh insights and discoveries expected down the road.Limitations, though, exist in current storage, processing and software, among other components.The U.S. Department of Energy’s four year $48 million Exascale Computing Project (ECP), started at the end of last year for science and national security purposes, plans to overcome those challenges. It explains some of the potential hiccups it will be running into on its Argonne National Laboratory website. Part of the project is being studied at the lab.To read this article in full or to leave a comment, please click here

IDG Contributor Network: New day or déjà vu

In July of last year, I believe that became the first to publicly suggest that Avaya should divest of the company’s data networking business. The one-year anniversary of my ”Cajun redux?” post is approaching and in a coincidence, around this same time Avaya will complete the sale of that part of the company to Extreme Networks. With this confluence of milestones, in this post will ask, does this signify a new day for Avaya or will, at some point down the road, we again be struck with that strange feeling of déjà vu?To read this article in full or to leave a comment, please click here

Thinking Through The Cognitive HPC Nexus With Big Blue

There are plenty of things that the members of the high performance community do not agree on, there is a growing consensus that machine learning applications will at least in some way be part of the workflow at HPC centers that do traditional simulation and modeling.

Some HPC vendors think the HPC and AI systems have either already converged or will soon do so, and others think that the performance demands (both in terms of scale and in time to result) on both HPC and AI will necessitate radically different architectures and therefore distinct systems for these two workloads. IBM, …

Why Cisco’s new intent-based networking could be a big deal
