About to go onstage in the Gold Room at the Palace Hotel to tell the world how Stackdriver and GCP make implementing SRE practices easier so you can have high reliability! #GoogleNext18
Woo, we did it! And I made it to my next session on time afterwards too!
Summary: we discussed four key areas: (1) why operability matters and how DevOps+SRE improve reliability, (2) why/how to set up SLOs & an error budget focused on measuring your customers' needs, (3) reducing TTD/R w/ tooling, and (4) transparent SLIs for debugging #GoogleNext18
Key tech: Stackdriver SLO for instrumenting, measuring, and alerting on error budgets. Stackdriver Monitoring features including Metrics Explorer by locality tags, metadata joins, and Query Notation for advanced joins. Exemplars for traces and metrics in one view. #GoogleNext18
All of these inspired by the best practices of 15+ years of SRE at Google. We want to make it easier for everyone to scale their systems without overloading their ops teams. #GoogleNext18
and we want to improve collaboration with our customers by reducing silos not just within companies but between customers and their cloud providers. Thus, transparent SLIs from us to you, and, soon, transparent SLIs from you to us if you want a single pane of glass. #GoogleNext18
Here are the slides for the talk on implementing SRE with help from Stackdriver tooling!

I'll link the YouTube video as soon as it's available as well. [btw this thread is one of the few times on Twitter that I *do* speak for my employer] drive.google.com/file/d/1iOMaYI… #GoogleNext18
As much as SRE is about doing more with tooling, it's also about culture change! Remember to check out cloud.withgoogle.com/next18/sf/sess… tomorrow about the cultural changes needed to make SRE work! #GoogleNext18
Session video is up for how to improve reliability by implementing SRE measurement and debugging techniques with Stackdriver!

Kudos to the video team for producing it on such a short turnaround! #GoogleNEXT18

Final talk I'll be getting to at #VelocityConf before I dash to Toronto: @IanColdwater on improving container security on k8s.
@IanColdwater She focuses on hardening her employer's cloud container infrastructure, including doing work on k8s.

She also was an ethical hacker before she went into DevOps and DevSecOps. #VelocityConf
She travels around doing competitive hacking with CTFs. It's important to think like an attacker rather than assuming good intents and nice user personas that use our features in the way the devs intended things to be used. #VelocityConf

My colleague @sethvargo on microservice security at #VelocityConf: traditionally we've thought of traditional security as all-or-nothing -- that you put the biggest possible padlock on your perimeter, and you have a secure zone and untrusted zone.
@sethvargo We know that monoliths don't actually work, so we're moving towards microservices. But how does this change your security model?

You might have a loadbalancer that has software-defined rules. And you have a variety of compartmentalized networks. #VelocityConf
You might also be communicating with managed services such as Cloud SQL that are outside of your security perimeter.

You no longer have one resource, firewall, loadbalancer, and security team. You have many. Including "Chris." #VelocityConf

Leading off the k8s track today is @krisnova on migrating monoliths to k8s! #VelocityConf
@krisnova [ed: p.s. her ponies and rainbows dress is A+++]

She starts by providing a resources link: j.hept.io/velocity-nyc-2…

The problems we're solving:
(1) why are monoliths harder to migrate?
(2) Should you?
(3) How do I start?
(4) Best practices #VelocityConf
.@krisnova is a Gaypher (gay gopher), is a k8s maintainer, and is involved in two k8s SIGs (cluster lifecycle & aws, but she likes all the clouds. depending upon the day). And she did SRE before becoming a Dev Advocate! #VelocityConf

Final keynote block: @lxt of Mozilla on practical ethics and user data. #VelocityConf
@lxt And also ethics of experimentation!

"just collect data and figure out later how you'll use it" doesn't work any more. #VelocityConf
We used to be optimistic before we ruined everything.

Mozilla also used to not collect data, and only had data on number of downloads, but its market share went down because they weren't measuring user satisfaction and actual usage. #VelocityConf

Next up is @mrb_bk on why marketing matters. #VelocityConf
@mrb_bk Hypothesis: marketing >> code in terms of software adoption. [ed: and this is why I became a developer advocate!] #VelocityConf
You need to consider community early when developing a product.

Always ask, "Why do people matter?" "Why does adoption matter?" #VelocityConf

Next up is @rogerm on O'Reilly's insights into trends with Radar. #VelocityConf
@rogerm They look at changes in search terms year on year; the two largest increases are k8s and blockchain. #VelocityConf
People are becoming less interested in broader topics and more interested in specific technologies e.g. pytorch. #VelocityConf
