PQ 158: Introducing NRE Labs For Network Automation Training

We dig into a new online tool, NRE Labs, designed to help network engineers learn the concepts and tools of network automation. NRE Labs was created by Juniper Networks, but it's a free and open source platform, and you can start learning now with no sign-in, no registration, and no paywall. Our guests are Matt Oswalt and Derick Winkworth.

AMD now wants to take on Nvidia in the data center

There’s no doubt that AMD’s graphics business has kept the company afloat when its CPU business stunk. More than once I saw quarterly numbers that showed all the profitability was coming from the GPU side of the market.The split between it and Nvidia is about 2:1, according to Steam analytics. Nvidia just has tremendous momentum and hasn’t lost it. And it allowed the company to branch out into artificial intelligence (AI) so thoroughly that gaming has almost become secondary to the firm. Not that they are leaving gamers hanging; they just aren’t the top priority any more.With AMD on the upswing on the CPU side, the company has decided to finally stop ceding the whole data center to Nvidia. And this week it introduced two new GPUs with the data center and HPC/AI workloads in mind.To read this article in full, please click here

Introducing Docker Enterprise 2.1 – Advancing Our Container Platform Leadership

Today, we’re excited to announce Docker Enterprise 2.1 – the leading enterprise container platform in the market and the only one designed for both Windows and Linux applications. When Docker Enterprise 2.1 is combined with our industry-proven tools and services in the new Windows Server application migration program, organizations get the best platform for securing and modernizing Windows Server applications, while building a foundation for continuous innovation across any application, anywhere.

In addition to expanded support for Windows Server, this latest release further extends our leadership position by introducing advancements across key enterprise requirements of choice, agility and security.

Choice: Expanding Support for Windows Server and New Kubernetes Features

Docker Enterprise 2.1 adds support for Windows Server 1709, 1803 and Windows Server 2019* in addition to Windows Server 2016. This means organizations can take advantage of the latest developments for Docker Enterprise for Windows Server Containers while supporting a broad set of Windows Server applications.

• Smaller image sizes: The latest releases of Windows Server support much smaller image sizes which means improved performance downloading base images and building applications, contributing to faster application delivery and lower storage costs.
• Improved compatibility requirements: With Windows Server 1709 and beyond, Continue reading

The future of Red Hat: How will IBM’s acquisition affect the company?

Only 11 days have passed since the announcement about IBM’s acquisition of Red Hat. Yet industry analysts are busily projecting the effects that this notable acquisition will have on the future of Red Hat.Having had a chance to compare notes with Richard Slater, principal consultant and DevOps/SRE Leader at Amido (an independent, vendor-agnostic technical consultancy focused on cloud native technology and located in London), I feel compelled to toss some reflections and a few hopes into the mix.To read this article in full, please click here

No Scripting Required to Start Your Automation Journey

The “everyone should be a programmer” crowd did a really good job of scaring network engineers (congratulations, just what we need!). Here’s a typical question I’m getting:

Do I need to be good in scripting to attend your automation course.

TL&DR: Absolutely not.

Setting Up Addressing and Routing: FTDv Fun

In my previous blog (Fun in the Lab: FTDv & FMC – Install and Deploy) we deployed a FMC VM and a FTDv VM and ended the blog with the FTDv successfully added to the FMC.

Now?  Now let’s add IP addressing for the FTDv and also set up routing protocol neighbor relationships.  I learned what I am about to show you from my co-worker and friend, Keith Brister.  So don’t thank me, thank Keith. 

I tossed together a ~29 minute YouTube.  Obviously you can watch the entire thing.  Or… here you go for the big sections.

• Overview – Start to 2:17 minutes
• Physical/Logical Mapping Overview – 2:18 to 9:25
• vSwitches, vmNICs and More in VMware – 9:26 to 16:20
• FTDv Configuring IP Adresses via FMC – 16:21 to 23:18
• FTDv Configuring IP Routing via FMC – 23:19 to 29:29

Done and Done.  Easy Peasy!

IETF 103, Day 4: Trusted Systems, IoT & IPv6

This week is IETF 103 in Bangkok, Thailand, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. Thursday actually represents the last day of the meeting this time, although there’s still several sessions to draw attention to.

SUIT is meeting first thing at 09.00 UTC+9. This is considering how the firmware of IoT devices can securely updated, and the architecture and information models for this will be discussed. There are three other drafts relating to manifest formats that are the meta-data describing the firmware images.

NOTE: If you are unable to attend IETF 103 in person, there are multiple ways to participate remotely.

DMM is the first of the afternoon sessions at 13.50 UTC+7, and there are several IPv6-related drafts under consideration. Proxy Mobile IPv6 extensions for Distributed Mobility Management proposes a solution whereby mobility sessions are anchored at the last IP hop router, whilst Segment Routing IPv6 for Mobile User Plane defines segment routing behaviour and applicability to the mobile user plane behaviour and defines the functions for that. There’s also three updated drafts on 5G implementations which may interest some.

To round off the week, there’s a choice Continue reading
