Cool Hacks Spotlight: Gloo Function Gateway

To close DockerCon Cool Hacks keynote, Idit Levine from Solo.io presented Gloo, a high-performance, plugin-extendable, platform-agnostic function Gateway built on top of Envoy.

Idit showed a demo that involved modernizing a traditional application; the classic Spring Pet Clinic sample app, by containerizing it and deploying it to Docker Enterprise Edition. She added functionality to the app by adding a microservice written in Go through a Gloo route. Then added more functionality by adding a Gloo route to an AWS Lambda function, creating a true hybrid cloud application combining legacy, microservices and serverless components.

She then provided a demo of Squash, that works with Gloo to live debug two microservices forming an application running in Kubernetes on Docker Enterprise Edition, one in Java from IntelliJ, one in Go from Visual Studio Code.

She finished her presentation by announcing and open sourcing Qloo, a GraphQL Server built on top of Gloo and the Envoy Proxy. This allows you to add GraphQL support without any coding to your existing application, and combining functions together in a workflow described as a graph.

See all these excellent demos in the video below, and view the presentation on SlideShare.

iNOG-10 & RIPE-Hackathon

In June 2018, I was lucky enough to attend the iNOG 10 session in Dublin, co-present a talk and also take part in the RIPE hackathon.

This post is a share on the experience. This isn’t because I’m running out of non-technical material, but this is to uncover both events for those that may want to attend, take part and experience what these kinds of sessions offer.

iNOG

The iNOG Irish Network Operators community surfaced briefly with events in 2005 (originally as the IENOG) but fell silent and was reborn in 2015 as the organisation
as it is today. Started by five returnees to Ireland and some economic migrants, the group has been seeing a high number of attendees to the events and over 700 members on Meetup! Not bad for something that came in on a started on a boat!!! (See below).

The group aims to deliver valuable content to the audience free of charge. Whilst ‘valuable’ has a variety of meanings depending on the audience, the general idea is to share experience of network based activities. As you can imagine, this is very wide ranging and just in the iNOG 10 session, talks were given on automation, data Continue reading

Check Out Our Newest Network Automation Course, Now Available On Our Streaming Site

We’ve just added a new Network Automation course, Network Automation with Ansible (v2), to our video library!



Instructor: Eric Chou

Course Duration: 4hrs 33min


Course Description

Ansible is quickly becoming the automation tool of choice for networking. This course aims to demystify Ansible and get you up and running with today’s technologies. After covering the basics, we’ll move on to the more advanced topics as they are applicable to network automation. This course will be cover the latest Ansible GA release 2.4 with some augments for upcoming development release 2.5.

Getting Started: Workflow Job Templates

Welcome to another post in the Getting Started series! Today we’re going to get into the topic of Workflow Job Templates. If you don’t know what regular Job Templates are in Red Hat Ansible Tower, please read the previously published article that describes them. It’ll provide you with some technical details that’ll be a useful jumping-off point for the topic of workflows.

Once you’re familiar with the basics, read on! We’ll be covering what exactly Workflow Job Templates are, what makes them useful, how to generate/edit one, and a few extra pointers as well as best practices to make the most out of this great tool.

What is a Workflow Job Template?

The word “workflow” says it all. This particular feature in Ansible Tower (available as of version 3.1) enables users to create sequences consisting of any combination of job templates, project syncs, and inventory syncs that are linked together in order to execute them as a single unit. Because of this, workflows can help you organize playbooks and job templates into separate groups.

Why are Workflows Useful?

By utilizing this feature, you can set up ordered structures for different teams to use. For example, two different environments (i. Continue reading

Research: P Fat Trees

Link speeds in data center fabrics continue to climb, with 10g, 25g, 40g, and 100g widely available, and 400g promised in just a few short years. What isn’t so obvious is how these higher speeds are being reached. A 100g link, for instance, is really four 25g links bundled as a single link at the physical layer. If the optics are increasing in speed, and the processors are increasing in their ability to switch traffic, why are these higher speed links being built in this way? According to the paper under investigation today, the reason is the speed of the chips that serialize traffic from and deserialize traffic off the optical medium. The development of the Complementary metal–oxide–semiconductor, of CMOS, chips required to build ever faster optical interfaces seems to have stalled out at around 25g, which means faster speeds must be achieved by bundling multiple lower speed links.

Qualcomm/Facebook gigabit Wi-Fi field trials to start in 2019

How should a company develop when its growth is dependent on availability of internet? Build out the internet is probably the answer. And that’s just what Facebook intends to do.The social network has just nabbed Qualcomm to help build its 2016-announced 60GHz urban Wi-Fi network, says Qualcomm. The chip maker recently announced that that the companies intend to start trials of the high-speed broadband solution sometime around mid-2019.“This terrestrial connectivity system aims to improve the speed, efficiency, and quality of internet connectivity around the world at only a fraction of the cost of fiber,” Qualcomm says in its release.To read this article in full, please click here

BrandPost: What is Fiber Densification?

Ciena Byline: Helen XenosSenior Director, Portfolio Marketing There is a new term that is increasingly cropping up in networking conversations: densification. Ciena’s Helen Xenos explains what this is and how it is elevating the end user experience.The term “network densification” is being used more often in relation to wireless network deployments, and more recently, “fiber densification” has become a hot a topic of discussion.  So, what exactly is densification? To read this article in full, please click here

While no one was looking, California passed its own GDPR

The European Union’s General Data Protection Regulation (GDPR) is widely viewed as a massively expensive and burdensome privacy regulation that can be a major headache and pitfall for American firms doing business in Europe. Many firms, including Facebook, have sought ways around the law to avoid having to deal with the burden of compliance.Well, there is no weaseling out now. Last week, with no fanfare, California Governor Jerry Brown signed into law AB375, the California Consumer Privacy Act of 2018, the California equivalent of GDPR that mirrors the EU law in many ways.To read this article in full, please click here
