The Unicorn Project
And The Five Ideals

@RealGeneKim
My Definition of DevOps
The architecture, technical practices, and cultural norms
that enable us to…
increase our ability to deliver applications and services...
quickly and safely, which enables rapid experimentation
and innovation, and the fastest delivery of value to our
customers…
while ensuring world-class security, reliability, and stability...
…so that we can win in the marketplace.

@RealGeneKim
The Problems That Still Remain
§ Absence of all the invisible structures needed to
enable developer productivity
§ The orthogonal problem of getting data from
where it resides to where it needs to be used
§ Strong opposition to support new ways of
working
§ Ambiguity on what behaviors needed to support
during a transformation

@RealGeneKim
The Five Ideals
1. Locality and Simplicity
2. Focus, Flow, and Joy
3. Improvement of Daily Work
4. Psychological Safety
5. Customer Focus

Ideal #1:
Locality and Simplicity

@RealGeneKim
The First Ideal: A Measure
§ Bus factor
§ Lunch factor

@RealGeneKim
How Many People Do You Need To Feed?
§ Two pizza team
§ Feeding everyone in the building
§ Schedule lunch with 43 different people

@RealGeneKim
Architecture Enables Teams To…
§ …make large scale changes to the design of its system without the
permission of someone outside the team, or depending on other
teams
§ ...complete its work without fine-grained communication and
coordination with people outside the team
§ ...deploy and release its product or service on demand, independently
of other services the product or service depends upon
§ ...do most of its testing on demand, without requiring an integrated
test environment
§ ...perform deployments during normal business hours with negligible
downtime

@RealGeneKim
The First Ideal: Code
§ Ideal: anyone can implement what they need by
looking at one file or module, and make the
needed change
§ Kubernetes sidecars
§ Spring (http-retry, Dependency Injection)
§ Aspect Oriented Programming
§ Not Ideal: to make your needed change, you
have to understand and change all the files and
modules

@RealGeneKim
The First Ideal: Code
§ Ideal: changes can be independently
implemented and tested, isolated from other
components (composability)
§ Not Ideal: in order for changes to be
implemented and tested, the entire system must
be present (e.g., integrated test environment)

@RealGeneKim
The First Ideal: Organization
§ Ideal: every team has the expertise, capability
and authority to satisfy customer needs
§ Not Ideal: in order to satisfy customer needs,
every team must escalate up two levels (and over
two, and down two)

@RealGeneKim
Rediscovering The Joy Of Programming
§ For decades, I self-identified as an Ops person…
§ 2 years ago, I’ve started to self-identify as Dev
§ Clojure / ClojureScript
§ LISP, functional programming, immutability
§ 3000 lines of Objective C -> 1500 lines of TypeScript/React -
> 500 lines of ClojureScript
§ Development is so fun, and these days, you can do
miraculous things with so little effort

@RealGeneKim
Why Functional Programming
§ The famous French philosopher Claude Lévi-Strauss
would say of certain tools, ‘is it good to think with?’
§ Core FP concepts
§ Immutability
§ Pure functions
§ Composability
§ Pioneered by LISP and ML. Popularized by OCaml,
Haskell, Clojure, Erlang, Elm, Elixir, ReasonML,
PureScript…

@RealGeneKim
Interestingly, It Portends Future Of Ops
§ Core concepts
§ Immutability
§ Pure functions
§ Composability
§ Look at…
§ Docker, Docker Compose
§ Kubernetes
§ Kubernetes sidecars
§ Event streams: Apache Kafka
§ Immutable databases: Datomic, Couchdb, Delphix
§ Git

@RealGeneKim
The Second Ideal: Focus and Flow
§ Ideal: your energy and time is focused on solving
the business problem, and you’re having fun
§ Not Ideal: all your time is spent trying to solve
problems you don’t even want to solve (e.g.,
YAML files, Makefile and spaces in filenames,
bash)

@RealGeneKim
Never Have I Valued Infrastructure More
§ Things I detest now
§ Everything outside of my application
§ Connecting anything to anything
§ Updating dependencies
§ Secrets management
§ Authentication and authorization
§ Data masking
§ Bash
§ YAML
§ Patching
§ Building kubernetes deployment files (mostly by Googling)
§ Why my cloud costs are so high

@RealGeneKim
The Value Of Platforms
§ Enable developer productivity
§ Self-service
§ On-demand
§ Immediacy and fast feedback
§ Focus and flow
§ Joy
§ Monitoring, deployment, feature flagging,
environment creation, security scans, orchestration,
database provisioning, test data management…

Flow: Dr. Mihaly Csikszentmihalyi
● State of Flow
● Two types of learning
● Procedural Learning
● One-shot Learning

@RealGeneKim
“What is your lead time
for changes?”
“How long does it take to go from
code committed to code successfully
running in production?”

@RealGeneKim
Source: The DevOps Handbook
Change Committed Into Version Control
Product Design and Development Product Delivery
(Build, Test, Deploy)
Create new products and services that solve
customer problems using hypothesis-driven
delivery, modern UX, design thinking
Enable fast flow from development to
production and reliable releases by
standardizing work, reducing variability and
batch sizes
Feature design and implementation may
require work that has never been done before
Integration, test and deployment must be
performed continuously, as quickly as possible
Estimates are highly uncertain
Cycle times should be well-known and
predictable
Outcomes are highly variable Outcomes should have low variability

@RealGeneKim
Making Changes When It Matters Most
“By installing a rampant innovation culture,
we performed 165 experiments in the peak three
months of tax season.”
–Scott Cook, Intuit Founder
“Our business result? Conversion rate of the
website is up 50 percent. Employee result?
Everyone loves it, because now their ideas can
make it to market.”

Predicts Performance With
Startling Accuracy?

doing deployments?”

Who hasn’t felt this?
You hire a bunch of developers, but you
still can’t ship the features you
promised…
…and maybe you even have the feeling
that things are slowing down…

build, or checks in code that breaks our tests

of the moment

Communication Paths As Predictor

@RealGeneKim
Slower Integrated Problem Solving
Not allowed
Integrated problem
solving
§ Leaders get incomplete information, too late
§ Teams don’t have access to expertise they need, deprived of full creative potential

@RealGeneKim
Typical Healthcare Scenario
§ Someone in Nursing has gloves that tear
§ Why does it need to escalate 8 levels to COO to
connect them with someone in supply chain?
§ Happens whenever integrated problem solving
must cross function silos
§ Nursing, Pharmacy, Transport, Supply Chain, Labs
§ And issues involving clinicians has to go to COO, over
to CMO, and then down

@RealGeneKim
Faster Integrated Problem Solving
§ Defined values streams, where relationships that enable integrated problem solving are
more linear and explicit
§ Easier for the organization to dynamically change, because the structure is simpler

@RealGeneKim
Amazon 2004
§ “Amazon.com started 10 years ago as a
monolithic application, running on a Web server,
talking to a database on the back end. This
application, dubbed Obidos, evolved to hold all
the business logic, all the display logic, and all the
functionality that Amazon eventually became
famous for: similarities, recommendations,
Listmania, reviews, etc.”
§ “The many things that you would like to see
happening in a good software environment
couldn’t be done anymore; there were many
complex pieces of software combined into a
single system. It couldn’t evolve anymore. The
parts that needed to scale independently were
tied into sharing resources with other unknown
code paths. There was no isolation and, as a
result, no clear ownership

The $1 Billion Amazon API Rearchitecture
1. All teams will henceforth expose their data and
functionality through service interfaces.
2. Teams must communicate with each other through
these interfaces.
3. There will be no other form of interprocess
communication allowed
4. It doesn't matter what technology you use, HTTP,
Corba, Pubsub, Bezos doesn't care.
5. Service interfaces without exception must be
designed from the ground up to be externalizable
6. Anybody who doesn't do this will be fired.
7. Thank you, have a nice day.

The Magic of 2000s Google Infrastructure
§ The miracle of Google platform in 2000s: present
