Technology Short Take 93

Welcome to Technology Short Take 93! Today I have another collection of data center technology links, articles, thoughts, and rants. Here’s hoping you find something useful!

Networking

Servers/Hardware

Nothing this time around. Feel free to hit me up on Twitter if you have links you think I should include next time!

Security

Cloud Computing/Cloud Management

  • The VMware Cloud-Native Apps group has a breakdown of some of the new features/functionality found in the 1.9 release of Kubernetes.
  • Via Maish Saidel-Keesing, I saw this post about 10 open source Kubernetes tools for highly effective SRE and Ops teams.
  • Richard Boswell has a series going on VMware Integrated OpenStack (VIO) and resource schedulers that is (so far) pretty good. Check out part 1 and part 2.
  • Daniel Sanche has a “Kubernetes 101” post that might be worth reviewing if you’re (somewhat) new to Kubernetes.
  • And while we’re on the topic of getting started with Kubernetes, you might find Chris Short’s post on that topic helpful as well.
  • Robin Vasan (via The New Stack) talks a bit about how various forces are shaping the software industry. There are a number of useful observations and takeaways from this article; one that jumps to mind is Vasan’s recommendation that “architects should actively consider finding abstractions that give them portability” when it comes to selecting/utilization cloud services. (I could insert a rant here about lock-in, but I’ll abstain…)
  • Kynan Rilee has a nice post on node affinity in Kubernetes scheduling.

Operating Systems/Applications

  • PowerShell Core 6.0 is now GA and supported by Microsoft.
  • Consul is a distributed key-value store that I’ve discussed a few times here on the site. One issue that has been difficult to address is boostrapping Consul in a cloud environment; this slightly older article addresses how new functionality (as of v0.7.1) can use cloud metadata to handle boostrapping a Consul cluster—and help address scaling that cluster up or down. And while I’m on the topic of Consul, you may also find this article on using Consul with a service mesh to be somewhat helpful as well (although this one isn’t as in-depth as the previous article).
  • Ariya Hidayat shows how to run Debian under WSL (Windows Subsystem for Linux).
  • This is a tool I’d like to take for a spin as soon as I get a chance.
  • I’m glad to see someone tackle the “microservices are the answer” mindset that seems to be going around these days. Check out Dave Kerr’s post. (He also includes links to more in-depth reading on related topics.)
  • Mark Peek talks about Dispatch, the open source serverless framework VMware recently released.

Storage

Virtualization

Career/Soft Skills

  • I really appreciated Jérôme Petazzoni’s frank look at how he reclaimed his productivity in the face of various challenges. There are some good tips here.
  • I found this article on five trends to avoid when founding a startup (no, I’m not planning to found a startup!) interesting reading. The article helps me see companies in a different light and judge/evaluate them by different criteria, which (IMHO) is generally pretty helpful.

OK, that’s all I have this time around. Check back in a couple weeks for the next Technology Short Take!
