One last purple shirt from #GoogleNext18...on my co-presenter @JamesMunnelly from @JetstackHQ! twitter.com/DanCiruli/status/1050404...

I guess I walked too much today at #GoogleNext18. Darn it!

It's all about the people shirts here at #GoogleNext18

Very excited to do a demo for the keynote of day 2 #GoogleNext18! Energy backstage is great.

All 17 of Google's data centres run carbon neutral #GoogleNext18 @anne_e_currie @PaulDJohnston

I'm in London all this week for the #GoogleNext18 event. If you're around and want to meet... Let's do it.

On my way to Google Cloud Next Japan! Zojouji temple and Tokyo tower. Nice photo op! (but the conference is in a modern hotel nearby 😁) #GoogleNext18

I was lucky enough to share the #GoogleNext18 stage with @n0r1 as she explained some tenets and practices of Google SRE, and I talked about how @IstioMesh helps you implement them. https://www.youtube.com/watch?v=XPtoEjqJexs

Yes! David Munro's "Introduction to Service Management with Istio Service Mesh" talk from #GoogleNext18 is up! https://www.youtube.com/watch?v=wCJrdKdD6UM So excited to watch.

"Tensorflow, deep learning and modern convnets". The video of the #GoogleNext18 session is out: https://youtu.be/KC4201o83W0

#GoogleNext18 #cloudhero is about to save the day!! Metreon 4 *right now*

#GoogleNext18 woooo!!!

#GoogleNext18 CloudHero!!!

If you stop by the Fifth Nine right now you might catch Cindy Kim telling the world about work she and I have been doing to bring SRE culture to @marketo!!! #GoogleNext18

It is a non-trivial scaling exercise and demand for CRE very much outstrips supply. [fin] #GoogleNext18

It's okay to have a 1 9 SLO, for instance, for pre-production testing.

Audience question about SRE training and certification: is google doing it? [ed: waving my hands saying YES!!! come talk to me in the red jacket or go find us at the Fifth Nine] #GoogleNext18

[ed: come talk to me at the Fifth Nine about my experiences turning on exemplars in combination with traces fleet-wide at Google]

Audience question about error budgets and tradeoffs involved; @btreynor discussing setting the right SLO number of nines. #GoogleNext18

.@btreynor emphasizing in response to a question about performance that APM is cheap compared to engineer time debugging outages. The impact in prod is unnoticeable, but even if it were 0.3% of CPU fleet-wide, it would still be worth it. #GoogleNext18

An open cloud question: will Stackdriver's backend be opensourced? A: no, because unless you have a few hundred thousand servers lying around it doesn't make sense; but the client libraries are all open source and interoperate so you can use same API w/ prometheus #GoogleNext18

but a lot of the issues we see aren't specific to SRE and are generic to *any* operational team structure. #GoogleNext18

Q: what are some of the common challenges people have with adopting SRE? A: some industries struggle with separation of roles in SOX etc. and not allowing people to modify and deploy code; other issues involve rules for data locality but tooling can help. #GoogleNext18

.@markcartertm hints that automated service dashboards are prevalent at Google when you use a common framework, and that there will be news by NEXT London on bringing this to the world. [ed: and people using Envoy and Istio often get this today] #GoogleNext18

Q: does this work in hybrid cloud? A: Stackdriver APM works regardless of environment but some of the logging stuff is dependent upon running in tagged VMs. #GoogleNext18

okay, I'll tweet this one: question about how to start culturally transforming with SRE. When you have devs/ops w/ different goals, things fall through because collaboration stops under deadlines/stress

The best way to fix this is common incentives & error budgets. #GoogleNext18

Now onto Q&A, with an extra incentive of @SREWorkbook copies to distribute to each person who asks a question, and snap spectacles for the best question. [livetweet ends here so I can help out & such] #GoogleNext18

OpenCensus exports to multiple different services; you don't just have to use Stackdriver, you can use Datadog, Prometheus, Zipkin, and so forth. At the same time. #GoogleNext18

To use these tools, you can just link in libraries and redeploy; it's open source and apache licensed & on Github.

Shoutout to OpenCensus! #GoogleNext18

[ed: we use profiling *all* the time within Google for thorny perf issues, and having it be more accessible is hugely valuable]

There's also a new Stackdriver Debug functionality that allows running live execution and debugging in prod. #GoogleNext18
