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

Is ‘DevOps’ considered harmful?

There are some who assert that DevOps is just a fashion

That it’s not needed and mightbe counter-productive

Is that true?

Let’s start by looking at what’shappening in our industry

Just for how long they need it.

No long term capital investment.

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

No more delivering parts that someone else puts together

No more handing your code off to others to use in production.

Service means something new now…

Cloud computing: power = money

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”

Compute power = money

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.

Cloud based applications work differently

“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’ht

In the software industry? You’re affected

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?

Quality

Too often we hear aboutfailures in systems that come about due a simple bug or vulnerability occurring in a complex situation or in a more organic environment than expected

Design / Feedback

Delivery Times

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….

Our Dev teams and Ops teams do not communicate properly

but we know what to do…

It’s a problem baked into our processes

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

We can’t afford not to

The imperative of DevOpsStartups 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…

The imperative of DevOps

The cost?

1. Standardized pipelines2. Dev and Ops teams working together3. Greatly expanding your horizons and your technical skills4. Leaving your comfort zone

Let’s see. What we need is

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

DevOps is the next evolution of Agile

#1 DevOps is not a technology it’s a movement

It’s about the next stage in workingtogether 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

DevOps enables effective use of cloud technologies #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 It 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..

DevOps and the Cloud is now a business agility goal

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 competitiveadvantage

.

#5 - 30x deliveries

#6 - 50% reduction in deployment failures

#7 2x likely to exceed important business goals

#8 And – by getting devops adopted you’re also more likely to get other more modern ideas happening too

“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?”

Last 2…

#9 – DevOps increases Job SatisfactionIT 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

SummaryBusinesses 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

What do to next..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

What to do next

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?

Maybe DevOps isnot all bad?

Thank You!
