5. @spoole167#DevOps
You should be able to leave today knowing
 How to explain what DevOps is and what it is not
 How to explain the benefits of DevOps and the Cloud to developers,
‘suits’ and IT specialists’
 Your next step in promoting DevOps

6. @spoole167#DevOps
There are some who assert
that DevOps is just a fashion
That it’s not needed and might
be counter-productive
Is that true?
Let’s start by looking at what’s
happening in our industry

The surge of Cloud
technologies that offer
compute ‘on tap’ are
making businesses
think differently about
how to buy and use
computing power

Easier than ever before
a business can buy a
CPU
Just for how long they
need it.
No long term capital
investment.

“Software as a Service”
profoundly changes the
way software is
designed and
delivered

18. @spoole167#DevOps
No more delivering
parts that someone else
puts together
No more handing your
code off to others to use
in production.

19. @spoole167#DevOps
Your software could go
into production
immediately
Like changing the teeth
on a tunnel boring
machine while it’s still
cutting
Ready for that?
Your
software

20. @spoole167#DevOps
Businesses see the opportunities here
Improved value for money, decreased
time-to-market, shorter time to value
“I can now get my ideas into
production in hours,days or weeks. I
can get immediate feedback AND then
I can improve the idea and repeat”

21. @spoole167#DevOps
Money changes everything
With a measureable and direct
relationship between $ and CPU/RAM
The financial success or failure of a
project is even easier to see
And that means…
Even more focus on value for money.

22. @spoole167#DevOps
“Everything fails all the
time [in the cloud]”
Werner Volgels, CTO, Amazon
Your application has to work in a
new way, in a new place.
Where strange behaviors
happen all the time
It needs to be ‘anti-fragile’

23. @spoole167#DevOps
Whatever you do – your
world is changing.
Old ways of developing and
delivering software are
being replaced with new,
faster, easier and more
powerful ,
alternatives

Ops problems can kill your
business. How much do
you know about Ops?

30. @spoole167#DevOps
Too often we hear about
failures in systems that come
about due a simple bug or
vulnerability occurring in a
complex situation or in a
more organic environment
than expected

31. @spoole167#DevOps
Case Study: A large bank uses agile techniques to create ‘complete’
solutions in < 3 weeks.
But It takes the Ops team about 15 months elapsed before the
deployment process starts and It take about 3 months to complete
deployment
why?
3 weeks to develop vs 3 months to make deployable = continuous
backlog
Continuous backlog = some projects never see the light of day
AND Ops talk to Dev 15 months after completion -> you can guess how
that turns out….

Would you believe < 1hr?
Case Study: A fashion retailer can show measureable increase in sales if
a item similar to that seen in the media can be placed on their on-line
store landing page within 1 hr of it appearing in public.
Each product placement is different so they need a fast, agile, approach
that does not jeopardize their on-line stores availability and quality.
We know how to do this..

Startups through to big businesses are
demanding the value that DevOps & Cloud
Technologies can offer
1. Production deployment pipeline up and
running in days
2. Updates published in hours or minutes
– continuously
DevOps helps transition an organization
into this new world…

53. @spoole167#DevOps
The cost?
1. Standardized pipelines
2. Dev and Ops teams working together
3. Greatly expanding your horizons and your technical skills
4. Leaving your comfort zone

10 Ways to convince
your team DevOps is
a force for good

55. @spoole167#DevOps
#1 DevOps is not a technology it’s a
movement
It’s about the next stage in working
together to deliver software
It’s about reducing delivery friction through
knowledge sharing
It’s about applying Agile ideas to Ops
It’s about collaboration and sharing
It’s about changing the culture
Manifesto for Agile Software
Development
Individuals and interactions over
processes and tools
Working software over comprehensive
documentation
Customer collaboration over contract
negotiation
Responding to change over following a
plan

56. @spoole167#DevOps
#2 Working together and exploiting “Infrastructure as Code’
approaches and technologies such as Docker, PaaS’s etc enable Ops
teams to bake in their requirements and Dev & QA teams to run in
modes much more like production
#3 Using virtualisation solutions like IaaS and PaaS makes
deployment easier and more ‘self-service’. This reduces the overhead
on the Ops team and hence improves delivery time
#4 Its works the other way too – getting Dev team monitoring and
diagnostics baked-in means less back and forth and no need to
access that production server..

57. @spoole167#DevOps
The demonstrable benefits of using DevOps and
Cloud tech are self evident enough now that
everyone wants to do it
Bringing Development & IT together to solve
deployment problems through sharing and
learning creates an organization with
“Strong IT performance”
This is becoming a major competitive
advantage
#5 - 30x deliveries
#6 - 50% reduction in
deployment failures
#7 2x likely to exceed
important business
goals
Source:puppetlabs2014

58. @spoole167#DevOps
“Using version control for scripts”
“Automating testing”
“Using TDD or BDD”
“we need to adopt Micro-services
design”
Why can’t we get our systems
proactively monitored?”
“How about Pair-programming – even
for ops
“Lets be honest – developers are lazy. If you have
to do it twice you’ll write a script. Ops teams
worry about everything the lazy developer didn’t
do. - like security,”
“low-friction organizations are good at recognizing
and removing obstacles – got an HR system that
gets in the way. Hate that corporate expense
tool? Wish you had a corporate expense tool
instead of the paperwork?”
“Since DevOps (and Agile) is about failing early and failing fast that approach
can spill over into the day to day culture – let it happen! Make it safe to fail..
And what about security – how about getting security ‘baked-in’ right at the
design time?”

59. @spoole167#DevOps
#9 – DevOps increases Job Satisfaction
IT Companies with high levels of job satisfaction are mostly likely to be
able to deliver consistently and with high quality. (Hint – who get
chosen 1st?)
#10 Adopting DevOps & the Cloud successfully make your
organisation well positioned for exploiting new capabilities – like
Analystics, BigData or even something like IBM’s Watson

60. @spoole167#DevOps
Businesses need to be able to react faster…
…DevOps and the Cloud are key enablers
DevOps is as much a game changer as Agile was…
…this is a Developer, QA and Ops “renaissance”
Don’t be afraid to learn and experiment…
…you’ll benefit even if the tech doesn’t survive
Agile moved you closer to the customer…
…DevOps moves you closer to the IT team

61. @spoole167#DevOps
1 – Lean and present Docker and PaaS style options to your peers.
Whether Ops or Dev you’ll see the value
2 – Find a buddy in the other camp.
3 – Get ‘real’ monitoring going across your infrastructure and applications
what ever you can monitor do so. And graph it, put up dashboards.
Look for and learn the warning signs of a failing system and get your peers
and detractors to see the value
(BTW – don’t monitor a system when you need to monitor the app!)
4 – Start to tackle automation
look for the places where others are challenged. And fix it for them.
Introduce Chef, Puppet, Bash, Groovy – the goal is automation 1st – cool tech 2nd

62. @spoole167#DevOps
Ask your organisation some difficult questions:
Deployment frequency?
Speed of deployment?
Deployment success rate?
How quickly service can be restored after a failed deployment?
Time from 1 line of code until in hands of the customer?
