People have asked me, “Are we doing DevOps, or are we doing SRE?” I’ve also heard (and this is worse): “We’re an SRE team – we don’t do DevOps.” These distinctions don’t make sense, because SRE and DevOps aren’t actually different things. SRE is DevOps. To be more precise, SRE is a specific implementation of […]| constructolution

I had the pleasure of contributing an article to the Reliability issue of Increment magazine. The article is titled Tracing a path to observability and chronicles our efforts at Glitch to gain visibility into our production systems and eventually make them more reliable. Give it a read and let me know what you think.| Mads Hartmann
At Glitch we’ve recently completed a project to migrate to SLO-based alerts. It’s too early to tell if this has been a success or not, but in this post I’ll write about our motivation for going down this route, and give an introduction to all the concepts you need to know, should you want to give it a go as well. SLOs are useful for a lot of things. As you’ll see below, we’re hoping that by implementing SLOs - and alerting on them - we’ll be able to improve communication during in...| Mads Hartmann
As part of an upcoming episode of Shift Shift Forward I answered a few questions about incident response. The description of the episode is:| Mads Hartmann
Recently Charity Majors asked a few hypothetical questions (tweet) around what you’d want out of a book on observability. I saw this as excellent opportunity to throw a bunch of questions I’ve been struggling with at an observability expert - so here are my questions ☺️| Mads Hartmann
As I have alluded to in the other parts of this little series of posts we’ve been investing in observability tools at Glitch to help us keep the platform reliable, even as more and more people run their apps on Glitch. In this post, I’ll focus on why we started investing in observability tools, where we are now and how we got there, and finally what we still haven’t figured out.| Mads Hartmann
At Glitch we have been investing in observability tools to help us keep the platform reliable, even as more and more people run their apps on Glitch.

I’ve been reading up on observability over the last three months. In this post I have organized the material into a sort of recommended reading order. It doesn’t reflect the order in which I read it, but I think this order would’ve made more sense.| Mads Hartmann

We often don't realize how noisy the errors have gotten until things are already well out of hand. After all, we've got shit to do. Deadlines to hit. By the time we decide to get serious about error management, a huge, impenetrable, meaningless backlog of errors has already accumulated. I call this stuff "slag."| Dan Slimmon
Last month, I had the unadulterated pleasure of presenting “No Observability Without Theory” at Monitorama 2024. If you’ve never been to Monitorama, I can’t recommend it enough. I think it’s the best tech conference, period. This talk was adapted from an old blog post of mine, but it was a blast turning it into a … Continue reading No Observability Without Theory: The Talk| Dan Slimmon
If you’re a junior engineer at a software company, you might be required to be on call for the systems your team owns. Which means you’ll eventually be called upon to lead an incident response. And since incidents don’t care what your org chart looks like, fate may place you in charge of your seniors; … Continue reading Leading incidents when you’re junior| Dan Slimmon
It only takes a few off-the-rails incidents in your software career to realize the importance of writing things down. That’s why so many companies’ incident response protocols define a scribe role. The scribe’s job, generally, is to take notes on everything that happens. In other words, the scribe produces an artifact of the response effort. … Continue reading Fight understanding decay with a rich Incident Summary| Dan Slimmon

Whilst there are some great examples of how to assess infrastructure as code dynamically with things like the Center for Internet Security‘s Docker benchmark and CoreOS‘s Clair, these kinda run a little too late in the pipeline for my liking.
