After a decade of vendor consolidation that saw some of the world’s biggest IT firms acquire first-class HPC providers such as SGI, Cray, and Sun Microsystems, as well as smaller players like Penguin Computing, WhamCloud, Appro, and Isilon, it is natural to wonder who is next. …
HPC In 2020: Acquisitions And Mergers As The New Normal was written by Michael Feldman at The Next Platform.
It’s hard to believe that it’s been eight years since I wrote my most controversial post ever. I get all kinds of comments on my NAT66 post even to this day. I’ve been told I’m a moron, an elitist, and someone that doesn’t understand how the Internet works. I’ve also had some good comments that highlight a specific need for tools like NAT66. I wanted to catch up with everything and ask a very important question.
WHY?
APNIC had a great post about NAT66 back in 2018. You should totally read it. I consider it a fair review of the questions surrounding NAT’s use in 2020. Again, NAT has a purpose and when used properly and sparingly for that purpose it works well. In the case of the article, Marco Cilloni (@MCilloni) lays out the need to use NAT66 to use IPv6 at his house due to ISP insanity and the latency overhead of using tunnels with Hurricane Electric. In this specific case, NAT66 was a good tool for him to use to translate his /128 address to something useable in his network.
If you’re brave, you should delve into the comments. A Continue reading

Every person joining your team has the same question on Day One: how do I find and connect to the applications I need to do my job?
Since launch, Cloudflare Access has helped improve how users connect to those applications. When you protect an application with Access, users never have to connect to a private network and never have to deal with a clunky VPN client. Instead, they reach on-premise apps as if they were SaaS tools. Behind the scenes, Access evaluates and logs every request to those apps for identity, giving administrators more visibility and security than a traditional VPN.
Administrators need about an hour to deploy Access. End user logins take about 20 ms, and that response time is consistent globally. Unlike VPN appliances, Access runs in every data center in Cloudflare’s network in 200 cities around the world. When Access works well, it should be easy for administrators and invisible to the end user.
However, users still need to locate the applications behind Access, and for internally managed applications, traditional dashboards require constant upkeep. As organizations grow, that roster of links keeps expanding. Department leads and IT administrators can create and publish manual lists, but those become Continue reading

Recently, I’ve been working to remove unnecessary complexity from my work environment. I wouldn’t say that I’m going full-on minimalist (not that there’s anything wrong with that), but I was beginning to feel like maintaining this complexity was taking focus, willpower, and mental capacity away from other, more valuable, efforts. Additionally, given the challenges I know lie ahead of me this year (see here for more information), I suspect I’ll need all the focus, willpower, and mental capacity I can get!
When I say “unnecessary complexity,” by the way, I’m referring to added complexity that doesn’t bring any real or significant benefit. Sometimes there’s no getting around the complexity, but when that complexity doesn’t create any value, it’s unnecessary in my definition.
Primarily, this “reduction in complexity” shows up in three areas:
Readers who have followed me for more than a couple years know that I migrated away from macOS for about 9 months in 2017 (see here for a wrap-up of that effort), then again in 2018 when I joined Heptio (some details are available in this update). Since switching to Fedora on a Lenovo Continue reading

In this episode, hosts Brian O’Sullivan and Roopa Prabhu are joined by Kernel of Truth podcast guest pros Pete Lumbis and Rama Darbha. The group looks back at 2019, discussing what they learned from the year and then move on to their 2020 predictions. Want a teaser? Automation was a hot topic in 2019 not just on our podcast but with our customers. It’s become less of a “nice to have” and more of a “need to have.” If you’re hungry for more 2019 retrospect and 2020 predictions, be sure to listen to this jam-packed podcast.

I always tell networking engineers attending our Building Network Automation Solutions online course to create minimalistic data models with (preferably) no redundant information. Not surprisingly, that’s a really hard task (see this article for an example) - using a simple automation tool like Ansible you end with either a messy and redundant data model or Jinja2 templates (or Ansible playbooks) full of hard-to-understand and impossible-to-maintain business logic.
Stephen Harding solved this problem the right way: his data center fabric deployment solution uses a dynamic inventory script that translates operator-friendly fabric description (data model) into template-friendly set of device variables.
