Portworx sponsored The New Stack’s coverage of KubeCon+CloudNativeCon North America 2019.
While you may thinking of Kubernetes as the future of computing, but it was, until recently, still stuck in the past in one way, namely that it was built on IPv4, the widely-used, though a soon-to-be-legacy version of the Internet Protocol upon which the internet was built.
The Internet Engineering Task Force has been long urging the internet service providers to move to IPv6, now that the world has exhausted the supply of 32-bit IPv4 addresses. With its 128-bit address space, IPv6 will offer an inexhaustibly supply of internet addresses.
“We ignored it,” admitted KubeCon + CloudNativeCon North America 2019 conference he gave with

Being
good looking is extremely important in your effort to becoming famous. So, you
may want to keep resetting your character until you score at 80% in the looks
department. The better looking you are and become throughout your life, the
easier it may be to become famous. Later, in life you can choose to have plastic
surgery or other procedures in order to help you become better looking.
Remember, we’re talking about a video game life simulator here, not Continue reading
It has been a great pleasure and an honor working with Tarique Shakil and Vinit Jain on this book below, deep-diving on this amazing LISP protocol.
I would like also to take this opportunity to thank Max Ardica, Victor Moreno and Marc Portoles Comeras for their invaluable help. I wrote the section on LISP Mobility deployment with traditional and modern data center fabrics (VXLAN EVPN based as well as ACI Multi-Pod/Multi-Site), however this could not have been done without the amazing support of these guys.
Implement flexible, efficient LISP-based overlays for cloud, data center, and enterprise
The LISP overlay network helps organizations provide seamless connectivity to devices and workloads wherever they move, enabling open and highly scalable networks with unprecedented flexibility and agility.
LISP Network Deployment and Troubleshooting is the definitive resource for all network engineers who want to understand, configure, and troubleshoot LISP on Cisco IOS-XE, IOS-XR and NX-OS platforms. It brings together comprehensive coverage of how LISP works, how it integrates with leading Cisco platforms, how to configure it for maximum efficiency, and how to address key issues such Continue reading
Extreme this week took the wraps off new automation software and switches aimed at helping customers quickly turn-up and manage new data-center networking segments.Key to the network vendor’s data-center plans is an upgraded version of its Extreme Data Center Fabric, which has been available for over a year and is now upgraded to let customers deploy a fabric in minutes. Once devices are cabled togtther and powered on, customers run the Extreme Fabric Automation application from any Extreme SLX spine or leaf switch, which then confirms configuations, validates and tests the network to ensure it is set up and operating correctly.To read this article in full, please click here

Internet security is accomplished by many
unsung heroes. People who put their talent and passion into improving the
Internet, making it secure and trustworthy. This is a feature of the Internet: security
isn’t achieved through a central mandate but through the hard work and tenacity
of individuals working across the globe.
Rachel Player, a cryptographic researcher, is one of those unsung heroes. She’s just been awarded the Radiant Award from the Internet Security Research Group, the folks behind Let’s Encrypt, for her work in post-quantum cryptography and homomorphic encryption. Homomorphic encryption allows people to do computations on encrypted data, so that information can remain private and still be worked with. This is a highly-relevant field in any area that deals with sensitive and personal data, such as medicine and finance. Player is also interested in lowering the barriers for young people – young women, especially – to work professionally on topics like cryptography.

Today, we’re excited to open source Flan Scan, Cloudflare’s in-house lightweight network vulnerability scanner. Flan Scan is a thin wrapper around Nmap that converts this popular open source tool into a vulnerability scanner with the added benefit of easy deployment.
We created Flan Scan after two unsuccessful attempts at using “industry standard” scanners for our compliance scans. A little over a year ago, we were paying a big vendor for their scanner until we realized it was one of our highest security costs and many of its features were not relevant to our setup. It became clear we were not getting our money’s worth. Soon after, we switched to an open source scanner and took on the task of managing its complicated setup. That made it difficult to deploy to our entire fleet of more than 190 data centers.
We had a deadline at the end of Q3 to complete an internal scan for our compliance requirements but no tool that met our needs. Given our history with existing scanners, we decided to set off on our own and build a scanner that worked for our setup. To design Flan Scan, we worked closely with our auditors to understand Continue reading

For the Internet of Things to become ubiquitous, many believe that inefficiencies in the powering of sensors and radios has got to be eliminated. Battery chemistry just isn’t good enough, and it’s simply too expensive to continually perform truck-rolls, for example, whenever batteries need changing out. In many cases, solar battery-top-ups aren’t the solution because that, usually-fixed, technology isn’t particularly suited to mobile, or impromptu, ad hoc networks.Consequently, there’s a dash going on to try to find either better chemistries that allow longer battery life or more efficient chips and electronics that just sip electricity. An angle of thought being followed is to wake-up network radios only when they need to transmit a burst of data. Universities say they are making significant progress in this area.To read this article in full, please click here
This morning’s keynotes were, in my opinion, better than yesterday’s morning keynotes. (I missed the closing keynotes yesterday due to customer meetings and calls.) Only a couple of keynotes really stuck out. Vicki Cheung provided some useful suggestions for tools that are helping to “close the gap” on user experience, and there was an interesting (but a bit overly long) session with a live demo on running a 5G mobile core on Kubernetes.
Running Large-Scale Stateful Workloads
Due to some power outages at the conference venue resulting from rain in San Diego, the Prometheus session I had planned to attend got moved to a different time. As a result, I sat in this session by Lyft instead. The topic was about running large-scale stateful workloads, but the content was really about a custom solution Lyft built (called Flyte) that leveraged CRDs and custom controllers to help manage stateful workloads. While it’s awesome that companies like Lyft can extend Kubernetes to address their specific needs, this session isn’t helpful to more “ordinary” companies that are trying to figure out how to run their stateful workloads on Kubernetes. I’d really like the CNCF and the conference committee to try Continue reading
