Ansible 2.6: Your Time Has Come!

Ansible-2.6

Guess what!? Another release has come upon us! Your time has come to upgrade to Ansible 2.6-”Heartbreaker.” Utilize some great updates to automate to your heart’s desire, and avoid being heartbroken. See what I did there? 

Let’s dive right into some of the changes.

Deprecation

One little bit of house cleaning before getting into the rest of the fun. The deprecated task option always_run has been removed, please use check_mode: no instead.

For any more information on behavioural changes from Ansible 2.5 to Ansible 2.6, please check out the Porting Guide.

Memory Utilization Improvements

In the development cycle of 2.6, we started to tackle a memory utilization problem that some of our users experienced in Dynamic Includes. In some cases, we have seen “roughly a drop of 50% memory consumption,” and in one scenario we had seen execution times of 21 seconds down to 8 seconds after the change was applied. Cool little bit, a bunch of these fixes were also back-ported to Ansible 2.5 as well as Ansible 2.4! In a future blog post, we plan to go into more detail of what was done to improve upon Dynamic Includes. Also, Continue reading

BrandPost: Coherent Optics: Taking Fiber Optics to the Next Level

What is coherent optics?At its most basic, coherent optical transmission is a technique that uses modulation of the amplitude and phase of the light, as well as transmission across two polarizations, to enable the transport of considerably more information through a fiber optic cable. Using digital signal processing at both the transmitter and receiver, coherent optics also offers higher bit-rates, greater degrees of flexibility, simpler photonic line systems, and better optical performance. It’s a web-scale world. On-demand content, bandwidth-hungry mobile apps, high-definition video streaming, and new cloud-based IT applications are driving massive scale and unpredictable traffic patterns. Network capacities are increasing by 25% to 50% every year, and systems running at 10 Gb/s just cannot keep up with this kind of rapid scalability.To read this article in full, please click here

In Defense of Humanity—How Complex Systems Failed in Westworld **spoilers**

 

The Westworld season finale made an interesting claim: humans are so simple and predictable they can be encoded by a 10,247-line algorithm. Small enough to fit in the pages of a thin virtual book.

Perhaps my brain was already driven into a meta-fugal state by a torturous, Escher-like, time shifting plot line, but I did observe myself thinking—that could be true. Or is that a thought Ford programmed into my control unit?

To the armies of algorithms perpetually watching over us, the world is a Skinner box. Make the best box, make the most money. And Facebook, Netflix, Amazon, Google, etc. make a lot of money specifically on our predictability.

Even our offline behaviour is predictable. Look at patterns of human mobility. We stay in a groove. We follow regular routines. Our actions are not as spontaneous and unpredictable as we'd surmise.

Predictive policing is a thing. Our self-control is limited. We aren't good with choice. We're predictably irrational. We seldom learn from mistakes. We seldom change.

Not looking good for team human.

It's not hard to see how those annoyingly smug androids—with their perfect bodies and lives lived in a terrarium—could come to Continue reading

DockerCon SF 2018 Cool Hacks Spotlight: Kubeflow

The closing keynote at DockerCon is traditionally the Cool Hacks keynote. This year, we featured three great hacks showing off innovative uses of Docker. In this post, I’d like to highlight one in particular, the Kubeflow demo with David Aronchick, and Michelle Casbon.

Machine Learning (ML) is becoming increasing popular, and important to enterprises. Kubeflow is an ML toolkit for Kubernetes, developed by Google. It’s a dedicated, portable and scalable approach to machine learning, using tools you’re already using to deploy other applications. It’s great because data scientists can use it to test out model creation on their laptops. And data engineers can take the models and use the power of Docker Enterprisein the cloud to further train and use the models in production.

In their demo, David and Michelle showed building an app using Kubeflow first with Docker Desktop and then on Docker Enterprise in the cloud. And they even took advantage of Google Cloud Tensorflow Processing Units native to the platform.

Check out their presentation and demo, and also check out Kubeflow to learn more.

IDG Contributor Network: 6 key themes shaping the future of network performance management

We live in an exciting era for IT. Countless new technologies are changing how networks are built, how access is provided, how data is transmitted and stored, and much more. Cloud, IoT, edge computing and machine learning all offer unique opportunities for organizations to digitally transform the way they conduct business. Different as these technologies are, they are unified by their dependence on a properly functioning network, on what might be called “network continuity.” The key component for achieving network continuity is visibility.It’s no secret that new and emerging technologies have always driven networking best practices. With such a wide range of business objectives and activities relying on IT, network performance really is a life or death issue for most companies. So, it’s critical that we maintain a firm grasp on the latest industry trends in order to make informed, strategic network management decisions.To read this article in full, please click here

Biddemu Bazil Mwotta, a 25 under 25 awardee, introduced the mobile-agribusiness-app AgroDuuka, which connects farmers directly with buyers in Uganda, his home country. AgroDuuka creates a market for local farmers, where there was none before, and eliminates the cost of working through intermediaries. To date, it has connected more than 800 smallholder farmers from 36 villages to buyers throughout Uganda. (You can read Roxanne Varza’s interview here).

The Internet Society: The AgroDuuka app, which you developed, bridges traditional barriers for farmers who want to access new markets by connecting them directly with buyers. Why did you develop the app?

Biddemu Bazil Mwotta: I grew up in an agricultural community in rural Uganda. My mother is a farmer, and I always used to Continue reading

Vodafone begins its trek with Voyager

“To boldly go where no one has gone before!”

Those words still echo in my mind as I remember watching the old Star Trek shows from yesteryear. It rings of adventure, of exploration, and of never settling for the known state of things.

It is these words that come to mind when I think of the new Voyager technology that is coming to market, which is designed to go boldly where no other technology in the Packet and Optical world has gone before. Voyager is the industry’s first combined routing, switching and optical platform all combined in a 1 RU footprint. The unique combo sets out to unifying both IP and optical to massively reduce complexity and costs. It will boldly transform the data center interconnect of today.

Vodafone-Voyager project

But it’s also the first open offering in the optical space. Cumulus is bringing its networking with S.O.U.L. (Simple. Open. Untethered. Linux) moxie and applying it to the transport and data center interconnect markets. This disaggregated solution dramatically reduces the cost of the current proprietary stack. It’s a solution with multiple players…
