BrandPost: Speeding the Migration of IoT Workloads to the Cloud

By: Michael Tennefoss, VP of IoT and Strategic Partnerships, Aruba, a Hewlett Packard Enterprise company.Moving IoT workloads to the cloud, and securely exchanging data between cloud IoT services and both legacy and new IoT devices, can entail months of custom engineering. Most IoT vendors send sensor and actuator data in non-interoperable or proprietary formats that must be reformatted to make them usable by cloud applications. Additionally, legacy IoT devices lack modern cybersecurity mechanisms and cloud-compatible software stacks. Replacing legacy devices with new ones is cost prohibitive, while the engineering work to make IoT data payloads usable can be significant. And these expenses may be recurring, e.g., when new IoT devices from different vendors are added over time, post-acquisition of a new company, or following a site refresh.To read this article in full, please click here

Myth Busting: You Can’t Use Packet Monitoring for Enterprise Security

Security teams today realize the value of packet monitoring for cybersecurity. As they find more uses for packet monitoring, they shatter the myth that the latter is insufficient on its own.

10-year server lifespan? That’s what one cloud service provider plans

A trend to extend the lifespan of servers beyond the typical three- to five-year range has companies such as Microsoft looking to add a few years of use to hardware that would otherwise be retired.The latest company to adopt this strategy is Paris-based Scaleway, a European cloud services provider that's sharing details about how it plans to get a decade of use out of its servers through a mix of reuse and repair.Scaleway decided the carbon footprint of new servers is just too large – server manufacturing alone accounts for 15% to 30% of each machine’s carbon impact. Reusing existing machines, rather than buying new ones, could significantly reduce e-waste.To read this article in full, please click here

Cloudflare’s commitment to the 2023 Summit for Democracy

On Tuesday, March 28, 2023, the US Government will launch the Summit for Democracy 2023, following up on the inaugural Summit for Democracy 2021. The Summit is co-hosted by the United States, Costa Rica, Zambia, the Netherlands, and South Korea. Cloudflare is proud to participate in and contribute commitments to the Summit because we believe that everyone should have access to an Internet that is faster, more reliable, more private, and more secure. We work to ensure that the responsibility to respect human rights is embedded throughout our business functions. Cloudflare’s mission — to help build a better Internet — reflects a long-standing belief that we can help make the Internet better for everyone.

Our mission and core values dovetail with the Summit’s goals of strengthening democratic governance, respect for human rights and human rights defenders, and working in partnership to strengthen respect for these values. As we have written about before, access to the Internet allows activists and human rights defenders to expose abuses across the globe, allows collective causes to grow into global movements, and provides the foundation for large-scale organizing for political and social change in ways that have never been possible before.

Wireshark Celebrates 25th Anniversary with a New Foundation

No doubt, countless engineers and hackers remember the first time they used newly-developed microscope to view cells for the first time ever: What was once just an inscrutable package had opened up to reveal a treasure trove of useful information. This year, the venerable Wireshark has turned 25, and its creators are taking a step back from this massively successful open source project, to let additional parties to help govern. This month, Sysdig, the current sponsor of Wireshark, launched a new foundation that will serve as the long-term custodian of the project. The

What Happened to Leaf Switches with Four Uplinks?

The last time I spent days poring over vendor datasheets collecting information for the overview part of Data Center Fabrics webinar a lot of 1RU data center leaf switches came in two form factors:

48 low-speed server-facing ports and 4 high-speed uplinks
32 high-speed ports that you could break out into four times as many low-speed ports (but not all of them)

I expected the ratios to stay the same when the industry moved from 10/40 GE to 25/100 GE switches. I was wrong – most 1RU leaf data center switches based on recent Broadcom silicon (Trident-3 or Trident-4) have between eight and twelve uplinks.

Ansible Validated Content: Introduction to infra.osbuild Collection

Introduction to the Image builder use case

During the last year we met with multiple edge customers, covering the automation needs for IT Linux infrastructure at scale across remote locations where there is often no IT staff on site. Think about retail stores, dark stores and warehouses where self-checkout, handhelds and POS devices hosting RHEL are distributed everywhere.

For industrial setups and manufacture, this could be the scenario for small factor servers and storage hosting logging monitoring to gather information about operational activities, which are located in secure facilities.

One of the recurrent needs for our customers with distributed devices is the ability to upgrade Linux devices faster, at scale, mostly due to regulations or security risks. Ideally, you should be able to patch at scale as soon as a vulnerability is identified.

The main challenge with the traditional RPM patching model is that it is incremental, and frequently some Linux devices might have slight differences. That is why there are new edge-focused capabilities and models that start with the premise that you could and should test a whole base image, and once it passes your validations, it should be deployed into all the target devices that Continue reading

VyOS dropped packet notifications

VyOS with Host sFlow agent describes how to configure and analyze industry standard sFlow telemetry recently added to the VyOS open source router platform. This article discusses sFlow dropped packet notifications support added to the latest release.

Dropped packets have a profound impact on network performance and availability. Packet discards due to congestion can significantly impact application performance. Dropped packets due to black hole routes, expired TTLs, MTU mismatches, etc. can result in insidious connection failures that are time consuming and difficult to diagnose. Visibility into dropped packets offers significant benefits for network troubleshooting, providing real-time network-wide visibility into the specific packets that were dropped as well the reason the packet was dropped. This visibility instantly reveals the root cause of drops and the impacted connections.

Home Automation — Finally Roller Curtains and Nightmares

< MEDIUM: https://raaki-88.medium.com/home-automation-finally-roller-curtains-and-nightmares-b8ef1fc473d9 >

Am a fan and enthusiast of home automation, tried various things in the past and now settled with few things which I would like to share.

Light Automation is the first and most popular thing to do — Initially I started wiring with PIR sensor available in Amazon, later upgraded the entire light system to Philips Hue and along with Philips Motion sensor, so far so good. Its expensive than my initial solution but had to choose that because of wired vs wireless situation in home
Smart-plugs are another common set of devices — while I have both combinations of commercially available one and also I personally flashed few of Sonoff smart switches with Tasmota firmware

. . .

Lets get to the Curtain Rollers — So for these here is the catch, I have a remote for these and thats about it, nothing more nothing less, My ideas were mostly around having network connectivity and manipulating them.

First and foremost thought that these are blue-tooth based and am wrong

I went to DFROBOT and bought IR-Transmitter and IR-Receiver, nope they dint work

I went Amazon and bought some other IR-transmitter and Receiver — Again, wasted a Continue reading

Enabling Nested-Virtualisation on Google cloud platform Instance

< MEDIUM: https://raaki-88.medium.com/enabling-nested-virtualisation-on-google-cloud-platform-instance-7f80f3120834 >

Important Excerpt from the below page.

https://cloud.google.com/compute/docs/instances/nested-virtualization/overview

You must run Linux-based OSes that can run QEMU; you can’t use Windows Server images.

You can’t use E2, N2D, or N1 with attached GPUs, and A2 machine types.

You must use Intel Haswell or later processors; AMD processors are not supported. If the default processor for a zone is Sandy Bridge or Ivy Bridge, change the minimum CPU selection for the VMs in that zone to Intel Haswell or later. For information about the processors supported in each zone, see Available regions and zones.

Though there are many use cases, I will speak from a networking standpoint. Let us say you need to do some sort of lab based on popular vMX Juniper or Cisco or any other vendor, if you have a bare metal instance, you have the ability to access the virtualised CPU cores and allocate them to the Qemu which will be the underlying emulator.

Issue

Almost by default most of the cloud providers will disable access to VT-x because of various reasons and some instances are not capable of supporting this by default. So either choose a custom instance with Continue reading

Predictive network technology promises to find and fix problems faster.

With the assistance of artificial intelligence (AI) and machine learning (ML), predictive network technology alerts administrators to possible network issues as early as possible and offers potential solutions.The AI and ML algorithms used in predictive network technology have become critical, says Bob Hersch, a principal with Deloitte Consulting and US lead for platforms and infrastructure. "Predictive network technology leverages artificial neural networks and utilizes models to analyze data, learn patterns, and make predictions," he says. "AI and ML significantly enhance observability, application visibility, and the ability to respond to network and other issues."To read this article in full, please click here
