Around me
devops, platforms,
and devops platforms
wat
start with definitions?
everyone has a platform
just kidding
we’ll come back to that
start with a story
start with my story
how did that happen?
Previously…
The power of automation!!!
automation at scale
turning the pages
I’m sure some of you have lived this too
maybe you didn’t(maybe you are about to)
this scenario played out over and over
everyone trying to solve similar problems
everyone making similar mistakes
what you automate is just as important as the fact you do
technology can resist automation
day 2 matters
the architecture matters
please quit building installers
please quit building brittle clever solutions
please quit building stuff that will predictably explode
Typical Day at Work
maybe you like being a hero?
maybe your co-worker does?
Operations is the secret sauce configuration
paying interest on technical debt
paying interest on automation debtarchitecture debt
process debt
everyoneover
and over
and over
WHERE IS YOUR DEVOPS NOW?
there has to be a better way
let’s rewind to definitions
What is devops?
I wrote a blog post.March 2010
devops• developers and operations can
and should work together
• system administration evolving to look more like software development
• evolving together as global community sharing solutions
devops - calms• culture
• automation
• lean
• metrics
• sharing
What is a platform?
Everyone has a platform…
might be the one guy who runs scripts
might be a bunch of configuration management
might be a public PaaS
if you can deploy and operate code in any capacity, you have a platform
maybe not be very good one
who cares about the word…
what about success?
‘devops actualized’ represent patterns that emerged in high performing
organizations that deliver highly available applications continuously at scale
devops, platforms, continuous delivery, microservices…
These things are all one…
faster and safer
BLAH BLAH BLAH BLAH
OODA LOOP
SMALL BATCHES
from now on, I’m going to call all that together… ‘Cloud Native’
what would cloud natives do?

Amazon, a bookstore in Seattle, deploys code to production every 11 seconds…
1 second
–Werner Vogels, CTO Amazon
“The traditional model is that you take your software to the wall that separates development and operations, and throw it over
and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day
operation of their software. It also brings them into day-to-day contact with the customer. This customer feedback loop is
essential for improving the quality of the service.”
Adrian Cockroft - ex-Netflix
What I learned from my time at Netflix.
Netflix Lessons
• Speed wins in the marketplace
• Remove friction from product development
• High trust, low process, no hand-offs between teams
• Freedom and responsibility culture
• Don’t do your own undifferentiated heavy lifting
• use simple patterns automated by tooling
• self service cloud makes impossible things instant

Netflix built a platform to enable self service deployment
Netflix built a platform to deploy and operate microservices
Netflix built a platform to continuously deliver software
Netflix built a platform that could protect itself from failure
What Netflix did not do is build a platform for general ad-hoc automation…
Constraints are the contract that allows a platform to keep promises.
Everyone has a platform.
What promises can your platform keep?

Everything as a Service
Now that we have a tool chain for release engineering, deployment,
and lifecycle management of large-scale distributed services…
What should we do with it?
deploy a self-service self-healing container scheduler, of course!

Cloud Native Runtime Platform
Cloud Native Infrastructure Automation
CPI
BOSH release
• role based access to resources
• run code on demand
• coordinate cross service configurations
• route public requests
• read and write persistent data
• add and remove resources
• record internal and external events
• isolate resources and failures
• measure performance/health
• detect and determine failure (plan & provoke failure)
• recover failures
• work tomorrow
What problems does it solve?
12 Factor Ops
your pipeline to continuously deliver microservices is ready
(and win buzzword bingo)
ask me about distributed runtime configuration, service discovery, and circuit breakers
the patterns proven successful building and operating highly
available systems with predictable scaling and failure characteristics

Cloud Native Contracts
structured contracts determine the promises a
platform can keep
simple patterns automated by tooling
simple patterns automated by tooling
simple patterns automated by tooling
This is the cloud native advantage
This is what helps organizations move
quickly at scale
Conway’s Law Rules Everything Around You
Motivated to change the relationship between people and the computers
I never set out to DO devops.
actually, needed to change the relationship between people and people
no one originally set out to do devops, continuous delivery, microservices, or platforms these were natural consequences
don’t fixate on the words, fixate on the outcomes
if you want to align people in your organization, think about the
interfaces, look at the promises they make and keep with each other.
Use tools and simple patterns to make doing the right thing the easy thing
can you keep promises?
DO YOU KEEP PROMISES
DOES YOUR PLATFORM HELP YOU KEEP PROMISES?
Thank You
