KubeCon 2019 Day 3 and Event Summary

Keynotes

Bryan Liles kicked off the day 3 morning keynotes with a discussion of “finding Kubernetes’ Rails moment”—basically focusing on how Kubernetes enables folks to work on/solve higher-level problems. Key phrase from Bryan’s discussion (which, as usual, incorporated the humor I love to see from Bryan): “Kubernetes isn’t the destination. Kubernetes is the vehicle that takes us to the destination.” Ian Coldwater delivered a talk on looking at Kubernetes from the attacker’s point of view, and using that perspective to secure and harden Kubernetes. Two folks from Walmart also discussed their use case, which involves running Kubernetes clusters in retail locations to support a point-of-sale (POS) application at the check-out register. Finally, there was a discussion of chaos engineering from folks at Gremlin and Target.

No Breakout Sessions

Due to booth duty and my flight home, I wasn’t able to attend any breakout sessions today.

Event Summary

If I’m completely honest, I didn’t get as much out of the event as I’d hoped. I’m not yet sure if that is because I didn’t get to attend as many sessions as I’d hoped/planned (due to problems with sessions being moved/rescheduled or whatever), if my choice of sessions was just poor, Continue reading

It Takes a Community: Kubernetes’ Long Road to Dual IPv4/IPv6 Support

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

Rachel Player Honored by Internet Security Research Group with Radiant Award

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.

To learn more, read the announcement by the Internet Security Research Group and Rachel Player’s blog post about her work and her interest in making the profession more accessible.

Introducing Flan Scan: Cloudflare’s Lightweight Network Vulnerability Scanner

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

IoT sensors must have two radios for efficiency

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
