Sys Admins, DevOps, SRE! Oh My!
✨ @to_emoji
Hello, I’m @bryanl
FinTech Startup

This is a journey not a destination
So, there’s DevOps…
… and then there is DevOps in the enterprise
Ok, Bryan… I’m intrigued
1. DevOps team
2. DevOps as a means to tackle a regulatory hurdle
3. DevOps as a way to remain Agile
Why does it have to be this way?
PEOPLE (you don’t believe me? think of any thing in
your life that’s hard. dig a little and find out that PEOPLE are the problem)
Corporate Communication 101
Small Team
Larger Team
Multiple Teams
Multiple lines of business with multiple teams
“My problems are the most important kinds of problems”
Developers only cause pain
I digress
It isn’t all bad
How do you know you are headed down the wrong
path?
How do you know you are headed down the wrong
path?
How do you know you are headed down the hard
path?
1. DevOps teams The HARD path
2. Optimization of process over people The HARD path
3. Developers not participating in the DevOps process The HARD
path
None
4. You have a DevSecOps group The HARD path
So the enterprise sounds like a horrible place…
… but it isn’t
Why does Bryan work for an enterprise? •People •Diversity •Challenge
DevOps path for the neophyte
Sys Admin
Run Service X
Run Service Y
Scales by growth
Dev Ops
Provide Tools As a Service (TaaS)
In support of the Agile process
Site Reliability Engineer (SRE)
Engineer first
“How do I do more with less?”
SRE is DevOps DevOps is SRE
What should you know?
Linux
More specifically…
bash
but remember, “scripting isn’t automation”
How networking works
How system services work
Tools of the space
Empathy
What would you say you do here?
Continuous Integration
Generate an artifact
Continuous Deployment
Monitoring
We are beyond Nagios
Long term trends
Time based comparisons
Alerts
Visibility
Logging
How can you be more effective?
Promote collaboration
Embrace your tooling and fill the gaps
It’s all about scale
Embrace simplicity
Documentation is Paramount
Documentation is Paramount • Who • What • When •
Where • Why • How
You should be involved in every phase of a system’s
design and development
Your focus is automation over more hands on keyboards
You scale solutions with engineering instead more people
Required reading

None
1. One less step
2. You are the 10x
3. You work with computers. Learn a programming language
AppOps A practical implementation of the DevOps practice
None
AppOps distilled • Continuous Integration • Continuous Deployment • Logging
• Metrics • Error Handling
AppOps distilled (2017 edition) • Continuous Integration • Continuous Deployment
• Logging • Metrics • Tracing • Error Handling
At a certain point, you aren’t a beginner any more
Remember One less step?
Make it one less step for others
Your application teams own business logic you own…
@peterbourgon
The power of words, technology, and empathy
–Bryan Liles We are the keepers We keep it up
We keep on the pager We keep it going
We are people and people ain’t perfect
We acknowledge this fact by building tools
The problem with tools is we become our tools
• Gophers • Pythonistas • Rubyists • Perl Rabble Rousers
Don’t fall for the team trap
Teams imply competition
It isn’t us versus them
It’s all of us for the betterment of all of
us
It’ll hurt, but progress is possible
We invoke empathy to solve problems for our users
