SPEEDING UP ENTERPRISES, ONE DEPLOY AT A TIME

HARRY TUTTLE, ENTERPRISE RELIABILITY ENGINEER

You’re asked to do something organizationally impossible

Your organization barely accomplishes the possible

You seriously consider a new line of work.

There is hope

Devops P(aaS)

Immutability Agile Lean Trust

!can be adopted,

successfully, sometimes,

maybe

…As with most things in the enterprise: !

(a) by accident or

(b) if you’re a monomaniac on a mission

Three observations: !

1. What comes first, culture or technology? 2. Getting others to see the system! 3. Architecture matters.

Culture or technology? Neither.

New KnowledgeEnvironmental Impacts and Needs

Behaviour Technology

Culture

These are reflexive (feedback loops).

Emotional Impacts & Needs

Can technology change an organization?

It can change entire societies! Of course it can.

Can you predict how technology will change an organization?

“This is impossible to automate”“The tool won’t let us” “Are you certified?”“I can’t believe you use that programming language, ew”

Let’s assume DevOps is “new knowledge” to the enterprise… This means it’s a technology-led change, by definition.

However, what technology are we speaking of?

….Configuration Management, Dev-Ops Collaboration, Clouds, Lean Value Streams, Chat Rooms, Wikis, Agile Methods, Immutable Containers, MicroServices, Big Data, Continuous Delivery …

!

The shape of the tools you choose, the environment you’re in, and the emotional state of the people you work with… drives the shape of behaviour you exhibit, drives the shape of the culture you live in.

EXAMPLES

1. Ops adopts config management(BladeLogic, Puppet, etc.)

2. Ops gets better

3. Dev doesn’t care, and still doesn’t test their code

1. Ops begins to transition to a self-service platform with new architecture constraints(Cloud Foundry, CLM, etc.)

2. Dev is forced to choose whether they change to fit the new hotness

3. A conversation begins

THE IMPOSSIBLE PROJECT OR, HOW ARCHITECTURE AND A GREAT TEAM SAVED OUR BUTTS

You’re called into the CFO’s office…

You need to build a system that will drive $2 billion annual revenue

You have no staff and seven weeks.

Solution: Guerilla Devops Warfare

!!!!!!!!!!!!

Executives with Knives

Second Line of Defence

!!!!!!!!

Product Owner

First Line of Defence

!!!

Coach & PMs

Team

Simple Technology !

Tomcat Microservice JAX-RS only

jQuery Puppet Bamboo

EC2 Oracle XE

MQ

Simple Process !

Weekly Sprints Demos Every Week

Want velocity? Architecture matters!

Devops is not just about Dev and Ops culture & tools

Software Architecture (how is it structured for scale and change)

Business (what are we doing and why)

Team/organization (who does what, who protects you)

Process (how do you coordinate work inside & expectations outside)

Results may be beautiful, but are fragile

Three observations: !

1. What comes first, culture or technology? 2. Getting others to see the system! 3. Architecture matters.
