Is “observability” just “instrumentation”? Or, monitoring sucks? No, you suck.

About this Episode

The DevOps kids have decided to come up with a new term “observability.” We get to the bottom of the WTF barrel on what that is - it sounds like a good word-project. Also, there’s a spate of kubernetes news, as always, and some interesting acquisitions. Plus, a micro-iOS 11 review.

Meta, follow-up, etc.

  • Patreon - like anyone who starts these things, I have no idea WTF it is, if it’s a good idea, or if I should be ashamed. Need some product/market fit.

Is “observability” just “instrumentation”?

  • Write-up from Cindy Sridharan.
  • This guy: “Thinking directionally, Monitoring is the passive collection of Metrics, logs, etc. about a system, while Observability is the active dissemination of information from the system. Looking at it another way, from the external ‘supervisor’ perspective, I monitor you, but you make yourself Observable.”
  • So, yes: if developers actually make their code monitorable and manageable…easy street! It’s a good detailing of that important part of DevOps.
  • Cloud Native Java has a good example with the default “observability” attributes for apps, and then an overview of Zipkin tracing.

Weekly k8s News

  • Heptio gets funding, now “has raised $33.5 million in funding to date.”
    • I think we’ll cover this press release in a WP episode.
  • Also, something called “StackPointCloud” now with the Istio.
  • Mesosphere adding K8s support - “Guagenti also noted that he believes that Mesosphere is currently a leader in the container space, both in terms of the number of containers its users run in production and in terms of revenue (though the company sadly didn’t share any numbers).”
  • "I think it’s fair to call Kubernetes the de facto standard for how enterprises will do container orchestration,” Derrick Harris.
  • Is Kubernetes Repeating OpenStack’s Mistakes? - Boris throwing bombs
  • Meanwhile, an abstract of a containers penetration study, from RedMonk: "Docker, is running at 71% across Fortune 100 companies. Kubernetes usage is running in some form at 54%, and Cloud Foundry usage is at 50%”
  • This update from the Cloud Foundry Foundation is a little more, er, “responsible” in pointing out flaws. Instead it just says there’s lots of growth and tire-kicking: 2016/2017 y/y shows those evaluating containers went up from 31% to 42%, while “using” ticked up a tad from 22% to 25%, n=540.
  • Oracle’s in the CNCF club! K8s on Oracle Linux, K8s for Oracle Public Cloud. “At this point, there really can’t be any doubt that Kubernetes is winning the container orchestration wars, given that virtually every major player is now backing the project, both financially and with code contributions.”
  • James checks in on Red Hat.

Acquisitions & more!

Security Corner

iOS 11

  • Coté has been running the beta. It seems fine.
  • There’s the usual Re-arrangement of how some gestures work that’s jarring at first, but after using it for awhile, you forget what they even are.
  • The extra control center stuff is nice.
  • The is interesting, but not too featureful.
  • The new photo formats are annoying because, you know, non-Apple things need to support it (which they seem to?)

Is Solaris dead yet?

  • Strongly confirmed rumors that Oracle is shutting it down.
  • This guy has written a big Solaris-brain to Linux-brain manifesto/guide, plus: “[n]owadays, Sun is a cobweb-covered sign at the Facebook Menlo Park campus, kept as a warning to the next generation.” SICK BURN!
  • Layoffs and more: “In particular, that employees who had given their careers to the company were told of their termination via a pre-recorded call — “robo-RIF’d” in the words of one employee — is both despicable and cowardly.”

VMware’s OpenStack

  • Little report form 451.
  • “Going forward, users pay a onetime $995-per-CPU socket license fee, in addition to ongoing support.”
