Technology Short Take 150

Welcome to Technology Short Take #150! This is the last Technology Short Take of 2021, so hopefully I’ll close the year out “with a bang” with this collection of links and articles on various technology areas. Bring on the content!

Networking

  • Ivan Pepelnjak has a post on running network automation tools in a container. In fact, he’s already built some container images, and the post has information on running tools from his prebuilt container image. Well worth reading!
  • Tom Hollingsworth likens networking disaggregation to “cutting the cord” and switching away from cable.

Servers/Hardware

Security

  • Nicholas Weaver (no, not that Nick Weaver) discusses the Log4Shell vulnerability.
  • The Log4J vulnerability and associated exploits has been on many folks' minds, so it’s only natural that many security companies have been looking into how to mitigate this attack vector. Aqua Security has a write-up on some of their analysis here.
  • This is an older post, but it doesn’t look like I’ve linked to it before, so I thought I’d include it here. Some Azure folks from Microsoft have published a threat matrix for Kubernetes. This is useful, in my opinion, because now platform operators have a “starting point” on the specific threats they need to try to mitigate.
  • I found this article on NSO/Pegasus a very interesting read. There’s also some great information in this Google Project Zero blog post.

Cloud Computing/Cloud Management

Operating Systems/Applications

Storage

  • Jeff Geerling describes his backup plan. (Jeff, if you aren’t aware, is a fairly prolific YouTube content creator.)

Virtualization

Career/Soft Skills

  • Katarina Brookfield recently shared her experience with the Certified Kubernetes Administrator (CKA) exam; you can find her notes here. Oh, and while we’re at it—you may find Curtis Collicutt’s experience with the Certified Kubernetes Security (CKS) specialist exam helpful as well.
  • This post has a list of “10 ways to prove yourself during remote work.” It seems to be primarily targeted at leadership-type roles, but readers may find a few useful tips here.

That’s a wrap! Not only for this Technology Short Take, but also for 2021. I hope that 2022 brings you much success and joy. As always, feel free to contact me on Twitter if you’d like to provide feedback, ask a question, or just say hello. I’d love to hear from you!
