SRE is an opinionated, concrete implementation of DevOps principles.
How many people have heard of/read the books? Fewer (~20%). #VelocityConf
Reliability is the most important property of your systems. If your systems are not reliable and do not meet your users' expectations, they won't use it, and your expensive system will have no users.
There is no such thing as a valuable system with no users. #VelocityConf
Reliability leads to user trust. The only measure of reliability is your users' perspective, not your logs or monitoring. They don't care if "it looks fine to me."
Give yourself a break, and don't demand perfection from yourself. It will force you to lie and fudge. #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
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
"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
