Final speaker of #SREcon: @deniseyu21 on why distributed systems are so hard.
@deniseyu21 She's an engineer on PCF, and also an avid artist and live-doodler of talks.

four things for today: a brief history lesson on distributed systems, CAP theorems, why networks partitions are hard/omnipresent, and how we can mitigate these risks. #SREcon
Once upon a time, everyone used a singular database that IT maintained.

But eventually IT became a business enabler we had to invest more in. Business analysts wanted to ask more complex questions, ML/NLP came along, and our requirements increased complexity... #SREcon

Next up: Pragmatic Automation, by @mluebbe #SREcon
"Automate yourself out of a job"

What if you're asked to automate something you have no idea how to do?
#SREcon
Backstory: Google has cloud regions. The original four:

- us-central1
- us-east1
- europe-west1
- asia-east1

Then we decided to build more. How?

#srecon @randyshoup: Learning from Learnings: Anatomy of Three Incidents
#srecon @randyshoup: Outage 1: Google App Engine Outage. App Engine was down globally for 8 hours. The playbook failed and triggered a cascading failure.
#srecon @randyshoup: Resolutions: increased traffic routing capacity, but more importantly, created a program to reduce probability of the same problem happening again.

Running excellent retrospectives: talking for humans
#SREcon
Goal of this tutorial:
- Learn how to run a retrospective.
- Create a safe space

Job running a retro:
- Facilitation
- Having a productive conversation
- Don't make bad jokes.

#SREcon
Facilitation: a.k.a. creating psychological safety, servant leadership.

Let's talk about language. English is blame-y. "you". Starting with "you" creates a line between participants.

I am somehow surprised when I encounter folks with such strong beliefs in the "Humans-Are-Better-At/Machines-Are-Better-At" approach to designing software. At this point I shouldn't be surprised, but still am. 1/n
This "HABA-MABA" philosophy has been so ingrained that it almost flies under the radar as worthy of attention to some.

Who will argue with "make the computers do the easy/tedious stuff so humans can do the difficult/interesting stuff"? (apparently, I will) 2/n
This notion was first described in the late 1940s, and it was known as "Fitts' List" - original is shown here... 3/n

Final talk of the day is my friend @ehashdn on monitoring k8s! #SREcon
She works as an SRE at @twosigma. She's also a k8s instrumentation SIG member.

Two Sigma runs one of the largest private cloud k8s deployments in the world.

And if you're interested in more on the k8s internals, attend @stillinbeta's workshop tomorrow! #SREcon
So, some information on observability, SLOs, collecting metrics, instrumenting k8s, and solving real problems in this talk.

Why are we trying to run our systems? We want to make users happy. We want to know when users might be getting unhappy before they tweet at us. #SREcon

Next talk: @roguelynn on improving web perf through tracing! #SRECon
@roguelynn She's an SRE at Spotify working on backend infrastructure and tooling around processing pipelines.

She also does internal open source evangelism, getting Spotify employees to release more OSS. #SREcon
The tl;dr of every chapter in @srebook, according to @roguelynn, is "use distributed tracing". There are so many services you don't own that you need to know how your code fits into the grand scheme.

Perf debuggging, capacity planning, and diagnosing problems. #SREcon

And now we're with: @JarenGlover on "Tackling Kafka, with a small team" #SRECon
For 3 years, "small team" is me.

Robinhood: democratising access to the financial markets. Saved $$$$ in customer commission fees already. #SRECon
This is not an authoritative talk; it's about providing context so that hopefully you avoid some of the pitfalls I ran into.

Organisational changes, technical evolution. #SRECon

And now: Testing in Production at Scale, by Amit Gud. #srecon
Let's start talking about Alice.

She owns service A at a company. It get requests from services B and C. B and C are upstream service.

Service A talks to D,E,F, which are downstream services. #SRECon
So, replace A with A'.

How do we test that? We need to check that B and C still work, and that we don't break D,E,F. Also, you need D,E,F to test A'.

So, we can set up an entire parallel stack, but that ends up very complicated. #SRECon

I'll be livetweeting @mipsytipsy's talk after lunch on monitoring vs observability and more. #SREcon
@mipsytipsy "I don't get my speaker's notes because I arrived a bit late, but I do get a unicorn instead, and I'm happy with that." -- @mipsytipsy #SREcon
"In the beginning, people wrote software for users, and we were motivated to fix it, because they would complain to us." #SREcon

Next up in Track 1 at #SREcon is @damonedwards on brownfield SRE in enterprises!
@damonedwards "You may think, 'I don't work in an enterprise', but you will eventually when your company becomes successful enough." --@damonedwards

You'll have multiple business lines, acquisitions, generations of tech debt... #SREcon
We see a lot of companies saying they're doing every buzzword. But when you look behind the scenes and talk to the ops folks, they're squeezed between the "DevOps/digital transformation" groups pushing to move faster, vs. locking things down from audit/security. #SREcon

Closing out #QConNYC in the chaos track is @otterbook on "turning it off and on again". He's promised to make my life "interesting" as a livetweeter so let's see how this goes.
@otterbook .@otterbook also has the best pre-talk dramatic/heroic amp-up music, which I'm digging. #QConNYC
This is going to be a very high audience participation talk, and is an experimental talk, says @otterbook. #QConNYC

Now: @jaqx0r on A theory and practice of alerting with service level objectives.

#SREcon
@jaqx0r this talk is based on Jamie's experiences being on a rotation that eventually burnt him out.

Showing a photo of his contribution to @alicegoldfuss oncall photo collection, where he looked happy, but didn't know he wasn't yet.

#SREcon
@jaqx0r context is the team was lowest rating in Google's SRE reviews for 2 6-month periods in a row. Not a great place to be.

So they got instructed to focus on fixing that and reducing oncall load.

After lunch, I'll be livetweeting an #SREcon talk on productionizing machine learning services by Google SREs @salim and @villaviejac, in their professional capacities... [ed: and I saw some 🔥🔥🔥 slides about ML privacy & ethics in their dress rehearsal so this gonna be good]
They are SREs but not necessarily ML scientists/researchers.

Data about what can go wrong has been gathered from 40+ interviews with varying teams. #SREcon
Myths: "machine learning is a black box." "you rarely have to rollback." "ML based monitoring is like other alerting." All nope. #SREcon

Next up, following neatly from incident response: @wcgallego on "Architecting a Technical Postmortem"
#srecon
I'm a Systems Engineer at Etsy. Run many postmortems.
- Database fall over
- Bad deploys
- The time everyone got sick
- Coffeemakers overflowed

Everything had something to learn. #srecon
Questions:
- who has never done a postmortem before?
- why do we have postmortems? (think about this through the talk)

Ask these before every meeting. They are our story times. #srecon

Up Now: @lizthegrey and @adam7mck on Resolving Outages Faster with Better Debugging Strategies #SREcon
I work with Liz, Adam is a top guy. There's some exciting stuff in this talk. Listen up! #SREcon
Liz - 8+ years at Google, now CRE. Excited about sharing things we've learnt with the world.

Adam - 18mths at Google, SRE/DevOps type-person for 8-10 years. Excited to share things that blew his socks off when joining Google.
