Cumulus content roundup: November

We’re at it again with the Cumulus content roundup- November edition. As always, we’ve kept busy this month with lots of great resources and news for you to read. From EVPN Underlay Routing Protocol to the benefits of Layer 3, we’ve rounded it all up right here, so settle in and stay a while!

From Cumulus Networks:

Choosing an EVPN Underlay Routing Protocol: We take a look at the options in routing protocols that could use as an underlay with the objective of understanding what might make them a fit or not for deployment in an EVPN network.

The Benefits of Flexible Multi-Cloud and Multi-Region Networking: Here we explore some of the reasons multi-cloud is fantastic for enterprises when they consider security, flexibility, reliability, and cost-effectiveness.

Cumulus Linux Automation with Standard Linux Tooling: This blog focuses on the different options available for modern automation, & how the Cumulus Linux approach provides the greatest amount of flexibility.

Cumulus Networks Open-Ended NCLU Net Example Command: NCLU is the always helpful Network Command Line Utility and supports both inspection and modification of Cumulus Networks configuration data.

Layer 3 can do it better. I’m convinced. You should be too.: Are you bringing the best solution Continue reading

BiB 062: Globally Scalable Microsegmentation With Illumio

Illumio is a security company focused on preventing breaches from spreading through an organization using microsegmentation. In this briefing, Illumio discussed their Policy Compute Engine Supercluster. The PCE Supercluster is, as the name implies, a cluster of Policy Compute Engines that spans regions or even the globe. Illumio cited several scenarios driving this available architecture of their central controller.

The post BiB 062: Globally Scalable Microsegmentation With Illumio appeared first on Packet Pushers.

Docker at DEVIntersection 2018

 

 

Docker will be at DEVIntersection 2018 in Las Vegas the first week in December. DEVIntersection now in its fifth year, brings Microsoft leaders, engineers and industry experts together to educate, network, and share their expertise with developers. This year DEVIntersection will have a Developer, SQL Server and AI/Azure tracks integrated into a single event. Docker be featured at DEVIntersection via the following sessions:

Modernizing .NET Applications with Docker on Azure

Derrick Miller, a Docker Senior Solutions Engineer, will deliver a session focused on using containers as a modernization path for traditional applications, including how to select Windows Server 2008 applications for containerization, implementation tips, and common gotchas.

Depend on Docker – Get It Done with Docker on Azure

Alex Iankoulski, a Docker Captain, will highlight how how Baker Hughes, a GE Company, uses Docker to transform software development and delivery. Be inspired by the story of software professionals and scientists who were enabled by Docker to use a common language and work together to create a sophisticated platform for the Oil & Gas Industry. Attendees will see practical examples of how Docker is deployed on Azure.

Docker for Web Developers

Dan Wahlin, a Microsoft MVP and Docker Captain, Continue reading

Logs from the Edge

Logs from the Edge

With Cloudflare Workers, our JavaScript environment at the edge, it is possible to send traffic logs to arbitrary locations. In this post we are going to discuss an example Worker implementation on how to achieve this. So if you are building or maintaining your own traffic logging/analytics environment, read on.

To build the underlying script we are going to leverage sub requests. Sub requests, which can be spawned from the initial HTTP/S request, can be used to aggregate and compose a response from several back end services, or, like in the example discussed here, to post data to a specific endpoint. Sub requests can be made asynchronously and after the initial request has been fully served to avoid adding unnecessary latency to the main request.

Logs from the Edge

The Worker Code

In this example we assume an Elastic stack has been set up at elk.example.com and has been configured to receive via HTTP/S PUT requests a number of fields for each log line. The full script that we are going to look at can be found below:

addEventListener('fetch', event => {
  event.respondWith(fetchAndLog(event));
})

async function fetchAndLog(event) {
  const response = await fetch(event.request);
  event.waitUntil(logToElk(event.request, response));
  return response;

Linux will seem to be everywhere in 2019

IDG 2019 just might be the Year of Linux — the year in which Linux is fully recognized as the powerhouse it has become. With Linux playing key roles in the Internet of Things (IoT), cloud technology, supercomputing and artificial intelligence (AI), and with a plethora of conferences and new releases on the horizon, Linux is poised to have a very exciting 2019. Let’s examine some of what we can expect to see.To read this article in full, please click here

What to expect of Linux in 2019

2019 just might be the Year of Linux — the year in which Linux is fully recognized as the powerhouse it has become. With Linux playing key roles in the Internet of Things (IoT), cloud technology, supercomputing and artificial intelligence (AI), and with a plethora of conferences and new releases on the horizon, Linux is poised to have a very exciting 2019. Let’s examine some of what we can expect to see.Linux behind the scenes The fact is that most people today are using Linux without ever knowing it — whether on their phones, online when using Google, Facebook, Twitter, GPS devices, and maybe even in their cars, or when using cloud storage for personal or business use. While the presence of Linux on all of these systems may go largely unnoticed by consumers, the role that Linux plays in this market is a sign of how critical it has become.To read this article in full, please click here

Using the Internet of Sound to transfer IoT data via speakers

Some kinds of data should be encoded onto an inaudible, near-ultrasound layer placed on top of normal, audible sounds — a process that could rapidly scale Internet of Things (IoT) adoption, says startup Trillbit.The company says that by doing that kind of overlay, any microphone and speaker is turned into a data-transfer device that then could be used for payments transfers, user authentication, and smart city applications such as digital locks.“There is no common universal protocol to connect Internet of Things,” Trillbit explains on its website. “Speakers [and microphones], which are already in place, and all around us” could perform connections.To read this article in full, please click here
