Dell EMC Q&A: Open Networking 2.0 – Disaggregating the Software Stack

Thanks to all who joined us for the Dell EMC Webinar: Open Networking 2.0 – Disaggregating the Software Stack. During the webinar Dell EMC discussed the architectural elements of the modern networking software stack and the role of open source technologies in it. After the webinar, we took questions from the audience. Read the full... Read more →

Thoughts on Open/R

Since Facebook has released their Open/R routing platform, there has been a lot of chatter around whether or not it will be a commercial success, whether or not every hyperscaler should use the protocol, whether or not this obsoletes everything in routing before this day in history, etc., etc. I will begin with a single point.

If you haven’t found the tradeoffs, you haven’t looked hard enough.

Design is about tradeoffs. Protocol design is no different than any other design. Hence, we should expect that Open/R makes some tradeoffs. I know this might be surprising to some folks, particularly in the crowd that thinks every new routing system is going to be a silver bullet that solved every problem from the past, that the routing singularity has now occurred, etc. I’ve been in the world of routing since the early 1990’s, perhaps a bit before, and there is one thing I know for certain: if you understand the basics, you would understand there is no routing singularity, and there never will be—at least not until someone produces a quantum wave routing protocol.

Ther reality is you always face one of two choices in routing: build a protocol specifically tuned Continue reading

OpenStack and CITC – Creating and learning about OpenStack networking

Part 1 – Examining the existing network

In my previous post, I was playing around with Cumulus in the Cloud (CITC) and how it was integrated with OpenStack. Now that I was playing with OpenStack in CITC, I wanted to dive deeper into the networking specific technology.

In this blog post I will be discussing how I leveraged a flat network to initially create simple instance deployments. Then I’ll dive more deeply into how I created a VXLAN network for my OpenStack instances to create more scalable east-west communication. In the previous post I used the CITC console as my primary interface for configuration. This time I will be using an SSH client and the direct SSH information, as the outputs I’m gathering have wider width that is easier to obtain via an SSH client.

To do so, I just clicked the SSH access button on the right hand side of the GUI. This provided me with the username, password and IP address that would allow me to use my own SSH client to connect to the CITC infrastructure.

For the uninitiated, here is a great intro doc into OpenStack networking. In addition, my colleague Eric Pulvino pointed me Continue reading

14 Linux apps that will change how you work

Linux productivity toolsThe sheer number of Linux apps available today is mind boggling and one category in particular has exploded over the last few years: productivity tools. While there are a few well-known apps such as LibreOffice and NeoOffice (both forks of OpenOffice), there are many more tools that can make your work easier. Here are a variety of killer Linux office productivity apps you may not know about. (Note: many of them are also available for macOS and Windows, so if you have to hop between operating systems, you can keep at least a semblance of consistency.)To read this article in full, please click here

Living In A Multi-Cloud World

A few months ago at Cloudflare’s Internet Summit, we hosted a discussion on A Cloud Without Handcuffs with Joe Beda, one of the creators of Kubernetes, and Brandon Phillips, the co-founder of CoreOS. The conversation touched on multiple areas, but it’s clear that more and more companies are recognizing the need to have some strategy around hosting their applications on multiple cloud providers.

Earlier this year, Mary Meeker published her annual Internet Trends report which revealed that 22% of respondents viewed Cloud Vendor Lock-In as a top 3 concern, up from just 7% in 2012. This is in contrast to previous top concerns, Data Security and Cost & Savings, both of which dropped amongst those surveyed.

At Cloudflare, our mission is to help build a better internet. To fulfill this mission, our customers need to have consistent access to the best technology and services, over time. This is especially the case with respect to storage and compute providers. This means not becoming locked-in to any single provider and taking advantage of multiple cloud computing vendors (such as Amazon Web Services or Google Cloud Platform) for the same end user services.

The Benefits of Having Multiple Cloud Vendors

Worth Reading: AI defeats CAPTCHA

San Francisco startup Vicarious has developed an AI that’s capable of reliably solving CAPTCHA, those automated security verification puzzles with squiggly or distorted lettering that you have to solve before being able to post a comment on a website, for instance. — Kimberly Mok @ The New Stack

How to build command groups with sudo

When managing your /etc/sudoers files, it’s a good idea to organize user privileges in ways that make them easier to manage over the long haul and to assign permissions based on the roles that users play in your organization.One very useful way to do that is to group related commands together — such as all commands related to running backups or managing web sites — and assign them to the individuals or groups that require these privileges.Setting up command groups in /etc/sudoers To create a command group, you use what is called a Cmnd_Alias in your /etc/sudoers file and give the new command group a meaningful name. Here are some examples. Note that full pathnames should be specified for all of the commands included in a group. Otherwise, you are likely to see an error like this when you try to exit visudo. And remember to only edit /etc/sudoers with the visudo command to allow it to warn you in ways like this and prevent errors.To read this article in full, please click here

IDG Contributor Network: Could the smart city mean the death of privacy?

As the Internet of Things grows and society becomes more interconnected, millions of citizens are beginning to experience a new kind of lifestyle in smart cities. These futuristic, digitally-dependent cities aren’t entirely without their downsides, however; human rights activist, futurist, and private citizens are increasingly concerned that the advent of smart cities could mean the death of privacy itself.So, what’s the truth behind smart cities and privacy, and is all the craze generated over tomorrow’s urban centers anything more than wild speculation? A quick review of smart cities as they’re developing now shows that, managed properly, they can be a huge boon to the populace – but privacy advocates will have to stay on their toes.To read this article in full, please click here

What happens when an IoT implementation goes bad?

When talking about the Internet of Things, it’s important to remember that the “internet” part is just as critical as the “things.” That my sound cryptic, but it can have dramatic real-world implications, as demonstrated by the failure last week of one-time Kickstarter darling Emberlight.INSIDER: 5 ways to prepare for Internet of Things security threats The company had raised $300,000 back in 2014 to fund development of its smart light socket designed to work with ordinary bulbs. But on November 16, Emberlight notified customers it was going out of business due to competition from larger competitors and imitators selling similar devices for a quarter of the price.To read this article in full, please click here

Feedback: Ansible for Networking Engineers

Got this feedback on my Ansible for Networking Engineers webinar:

This webinar is very comprehensive compared to any other Ansible webinars available out there. Ivan does great job of mapping and using real life example which is directly related to daily tasks.

The Ansible online course is even better: it includes support, additional hands-on exercises, sample playbooks, case studies, and lab instructions.

However, Ansible is just a tool that shouldn’t be missing from your toolbox. If you need a bigger picture, consider the Building Network Automation Solutions online course (and register ASAP to save $700 with the Enthusiast ticket).
