Docker in Higher Education: Announcing Tools & Resources for Teachers

Docker in Higher Education.png

At the beginning of the summer we published a blog post announcing the Docker Student Developer Kit and Campus Ambassador program. The positive reception from students has been overwhelming and we were so excited to see hundreds of applications flood in!

Many teachers took notice of the enthusiasm of their students and began to reach out, asking us for tools, resources and support in using Docker in the classroom and adding Docker to their curriculum. To this end we have put together a free package for teachers!

Making use of this offer will enable teachers to effectively use and teach Docker in the classroom as we will be able to provide:

  1. Free Tools: eliminating the need for students to install anything locally, thus saving you valuable class time
  2. Resources: the most up to date presentations, hands-on labs, workshops etc. on every topic for every skill level
  3. Support and recognition: you will have a dedicated contact at Docker to help you through the process and also be welcomed into the online Docker Teachers community where you can collaborate and learn from other educators

If you are a teacher at a higher-education institution who would like to unlock the benefits outlined Continue reading

The Huge Premium Intel Is Charging For Skylake Xeons

There is no question that Intel has reached its peak in the datacenter when it comes to compute. For years now, it has had very little direct competition and only some indirect competition for the few remaining RISC upstarts and the threat of the newbies with their ARM architectures.

The question now, as we ponder the “Skylake” Xeon SP processors and their “Purley” platform that launched in July, is this: Is Intel at a local maximum, with another peak off in the distance, perhaps after a decline or perhaps after steady growth or a flat spot, or is this the …

IDG Contributor Network: Why smart cities are crucial for autonomous cars

Autonomous cars are changing the way consumer drivers and auto manufacturers alike view transportation, with bold new players like Tesla joining long-standing industry giants like BMW in their quest for a truly independent car. More so than almost anything else, smart cities and their continued development are shaping the way these autonomous cars are designed, manufactured and used around our urban environments.So how exactly are smart cities reshaping the way developers approach building truly autonomous vehicles capable of guiding themselves? What does the future of the smart cities movement hold for autonomous cars, and vice versa? A quick look at these 21st Century innovations shows just how intertwined their fates are.To read this article in full or to leave a comment, please click here

One way to help Hurricane Harvey victims

Hurricane Harvey hit Texas last Friday as a Category 4 storm. Although Harvey's category was quickly downgraded, the storm lingered around for days, bringing 50 inches of rain to the greater Houston area.

As someone who was born in Houston, it's hard to see my former city hit with such destruction, and to know that many of my friends and fellow Houstonians are in need of help and assistance. Many families have had their entire house flooded out by the storm. Displaced residents are in a state of stagnation and are seeing their supplies diminishing by the day.

The Hurricane Relief app will allow visitors to your site to donate to one of the charities helping those impacted in Houston:

The Hurricane Relief App takes two clicks to install and requires no code change. The charities listed are recommended by NPR.

IDG Contributor Network: SD-WAN Simplified!

This blog post is going a bit outside my usual “make sense to the C-Level” slant. I wanted to get in the weeds about reviewing SD-WAN products. We all know that’s where the fun really is!I have been doing a bit of evaluation on SD-WAN products and their configurations from the network engineer’s perspective. I have looked at numerous vendors’ products, poured over install guides, and dusted off the CLI.Everyone who knows me can tell you I am a Cisco fanatic. Hands down, I would rather implement a Cisco technology rather than any other vendor by a 1000:1 ratio. I have spent a majority of my career as a network engineer, and the best network devices to configure and troubleshoot have been Cisco.To read this article in full or to leave a comment, please click here

What’s New in Docker Enterprise Edition Webinar Recap

WebinarScreenshot.png

The latest release of Docker Enterprise Edition (EE) allows organizations to modernize Windows, Linux, and Linux-on-mainframe applications—all with minimal disruption. The release also allows organizations to run containers at scale with advanced capabilities around secure multi-tenancy and policy-based automation.

In last week’s webinar, we walked through the key new features of this release and saw a demo of Docker EE in action. If you missed the webinar, you can watch it here:

Here are the top questions from the webinar:

Q: Can you provide more information about Windows support? Which version of Windows? Is this only available with Docker Enterprise Edition?

A: You can run Windows Docker containers either with Docker Community Edition for Windows (PC) which supports Windows 10 or Docker Enterprise Edition for Windows Server 2016 (including Nano Server). Docker EE Basic is included with the Windows Server 2016 license, and you also have the option to upgrade to EE Standard or EE Advanced for Windows Server 2016 to get complete lifecycle management capabilities, Docker Trusted Registry, and advanced security features like image signing and scanning.

Q: Is it possible to deploy the Windows containers on top of a native Linux host?

A: As a form of packaging Continue reading

Using FQDN for DMVPN hubs

I've done some testing with specifying DMVPN hubs (NHRP servers, really) using their DNS name, rather than IP address.

This matters to me because of some goofy environments where spoke routers can't predict what network they'll be on (possibly something other than internet), and where I can't leverage multiple hubs per tunnel due to a control plane scaling issue.

The DNS-based configuration includes the following:

 interface Tunnel1  
  ip nhrp nhs dynamic nbma dmvpn-pool.fragmentationneeded.net

There's no longer a requirement for any ip nhrp map or ip nhrp nhs x.x.x.x configuration when using this new capability.

My testing included some tunnels with very short ISAKMP and IPSec re-key intervals. I found that the routers performed the DNS resolution just once. They didn't go back to DNS again for as long as the hub was reachable.

Spoke routers which failed to establish a secure connection for whatever reason would re-resolve the hub address each time the DNS response expired its TTL. But once they succeeded in connecting, I observed no further DNS traffic for as long as the tunnel survived.

The record I published (dmvpn-pool.fragmentationneeded.net above) includes multiple A records. The DNS server randomizes the record Continue reading

NASA Supercomputing Strategy Takes the Road Less Traveled

For a large institution playing at the leadership-class supercomputing level, NASA tends to do things a little differently than its national lab and academic peers.

One of the most striking differences between how the space agency views its supercomputing future can be found at the facilities level. Instead of building massive brick and mortar datacenters within a new or existing complex, NASA has taken the modular route, beginning with its Electra supercomputer and in the near future, with a 30 Megawatt-capable new modular installation that can house about a million compute cores.

“What we found is that the modular approach …

Worth Reading: Multiple perspectives on technical problems and solutions

So what was this architecture review meeting all about? It was pretty simple, really. It was just a presentation by the engineer(s) looking for feedback on a solution they came up with, and Kellan and I would ask questions. The meeting was open to anyone in the company who wanted to attend. The hope was that many engineers would attend, actually. The intent here was to help the engineers describe their problem as thoroughly as they can, and by asking questions, we could help draw out any tacit assumptions they made in thinking through the problem. In a nutshell: it was a critical-thinking exercise, and we wanted engineers to want to do this, because it was ideally about providing feedback. —John Allspaw @Kitchen Soap
