STEP 0: instrument the code and use telemetry (logs, metrics, traces) to how the code actually works in production.

Reliable systems, good alerting and monitoring, and luck. 3 of the ingredients to making on-call not suck quite so much. Plus being paid for it, of course! @heyitsols on ‘Being Paid To Sleep’ at @DevOpsDaysLDN

@basti_tee A product or system designed without ongoing operational concerns will *appear* cheaper but likely end up costing significantly more in the long term compared to a system co-designed with the people who will actually operate it. 2/

Incidents? Those are just failure modes leaving the system.

"Software operability still suffers because #Devs are no closer to actually running the software that they build, and the SREs still don't have time to engage with Devs to fix problems when they arise.”

WARNING! You'll need PROPER observability. If you don't have proper introspection, the technical challenges will be almost impossible to overcome. In the mentioned example we were able to trace the annotated db queries through the complete code artifact.

Can we build #observable services without logs? @glenathan, Senior Software Engineer @geckoboard shares at #QConPlus a story of how it went: bit.ly/3w48gFw 💡Missed this talk? You can still register & have on-demand access to all the talks for 3 months. #Observability

@onejasonknight @bandanjot @AbsorbingStates That said, the what's more important than "project versus product" is that the funding and execution model for the software evolution keeps that software viable in the long term. Prefer sustainable pace and attention to operability rather then feature factory. 👍

@PierreVincent @glenathan This is so good to hear! 🙌 Weirdly, I was using (and wrote about) this kind of approach almost exactly 10 years ago: - Dynamics severity levels - Unique IDs - A focus on events #operability blog.matthewskelton.net/2012/12/05/tun…

Nice example of a useful, in-app scheduled maintenance message from @MiroHQ 👏 "Upcoming scheduled maintenance: Saturday, March 26, 2022 at 5:30 AM (your time). Miro will be unavailable for 1 hour." The "your time" bit is good #UX #operability #reliability

Very happy to see the discussion around developer experience. Now how about operator experience?

LARGE SYSTEMS USUALLY OPERATE IN FAILURE MODE, via @dangolant Or like I used to say, your distributed system exists in a continuous state of partial degradation. There are bugs and flakes and failures all the way down, and hardly any of them ever matter. Until they do.

@aleixmorgadas We at @ConfluxHQ have been doing a lot of work around reliability over the past 2 or 3 years. See reliabilitymodel.com for some ideas about exploring and measuring reliability. 👍

In 2021 and beyond, showing a generic "Oops. Something went wrong" 500 error page is not just user-hostile but exposes major flaws in the product engineering approach. ➡️ Design for the UX under error conditions. #operability #UX

I'm lucky to work with lots of great people here @weareglofox but it's so cool see @clintonsweetnam 1. Design a system with #testability and #operability as a primary concern from the outset and then 2. Share how he and his team did it with the whole Engineering Department😍
