Next talk at #VelocityConf is a sponsored talk by @beevek on moving fast without breaking things.

How do you decide when to measure and make course corrections?
@beevek If you make it cheaper and less risky to measure where you are and where you're going, then you'll be more efficient about accomplishing your goals and managing risks.

Reduce the scope of potential failures by checking them with the real world as soon as possible. #VelocityConf
How do we decide what to invest in? There's always more tests, metrics, and automation to write.

Prioritize where cost of failure and change velocity is the highest for your observability and risk management. #VelocityConf

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
