The Race to Deliver

your idea is probably competing against others with similar interests
how do we adopt agile practices inside of the rest of our organization

Stop Trippin’!

you do not wanna be that guy tripping over the stuff you can manage easily.
devops is about giving you a competitive advantage
devops is about delivering high quality operations setups

New Business Ideas

take us and our customers to new levels

Traditional IT Silos

traditionally we might have operations, dbas, networking people, release managers, etc.
a lot of smart people with generally narrow skill sets.
we see these environments as ruby gains more adoption.

Fragile Deployment

it becomes a balancing act to keep the production systems in a good state.
a lot production systems are “that box in the corner” you can’t touch.

That’s Just Dumb

looking in from the outside you wouldn’t believe how people do operations

That’s Crazy

WHY WOULD YOU EVER DO THAT?

Developer Dreamland

a lot of really creative hackers come up with stuff that’s difficult to support from operations
some developer in your org got an elephant to do a hand stand on his shiny new mac.
sometimes called “it works on my machine” syndrome

Operations Support

but your operations feel like they’re holding the elephant up
it requires them to have super human powers and a mexican wrestling mask

Support Fallout

it usually takes something terrible for people to realize it was a bad idea.

Developer Outrage

developers cry out, “it works on my machine!!!”
fuckin’ ops guys.

Finger Pointing

basically no one believes they are at fault, so and so isn’t “agile” enough
doesn’t accomplish the task at hand

Distaste for Change

historically operations hate introducing new things they have to support.
the default answer for “can we support X” becomes “NO!”
change control boards or something similar are introduced.

Distrust is Common

operations doesn’t trust developer’s code
developers feel like operations keeps them from delivering

How Can We Fix This?

Speeding Things Up

how do we get operations to work as quickly as a productive “agile” team?
how do we identify problems in operations/deployment earlier?

The Same Team

we’re all working toward the same goal, even though we’re different
it’s the job of the parties involved to bridge the gaps w/ the rest of their org

Helping Others Out

even though you still sort of think of yourself as different, lend a hand outside your group.
pair with your dba, or a developer. when was the last time you did that?

Automation

automation is historically an afterthought.
making system automation a ﬁrst class requirement, conﬁgs and/or provisioning.
we still can’t do really “brain dumps”

Testing

testing is still emerging in this area.
people are doing really cool stuff with cucumber.
we do a few different things at EY to validate automation.

Better Communication

starting the conversation early instead of waiting to engage other parts of your org
truly understanding the domain in question

Sysadmin Coders

embracing ruby and python to get the job done.
the best coders i know are often badass sysadmins too, they understand everything.

Shipping Early

avoid building something that really won’t get the job done.
get everyone who will be involved, involved early.
having the automation in place for operations early in the development cycle.

The Last Mile

“dev complete” is different from “live, in production, making us money”
hold up in wrapping up that last mile costs us money.

Make Everyone Happy

a workplace where you love everyone in every department is awesome.
it makes working on the product a pleasant experience.
same parts that make agile work for development can apply to the sysadmin’s work.

where’s my BOFH?

they’re still there, but he’s likely your “Buddy Operator from Helena”
tools and approaches exist now that align with good system administration goals.
these tools should start being adopted now

where’s this headed?

adopting agile-like practices in all aspects of delivering a product.
speciﬁcally, operations should step up their game because they’re being left behind.

The Cloud

while no one clearly deﬁnes what “the cloud” is
i think of it as automated provisioning of IT infrastructure
devops makes even more sense because we have as much disposable hardware as we want

The Penguins are Coming!

never..ending..stream..of..unix..boxes
how do you get them all do your bidding?

Puppet

puppet is a tool from the guys at puppetlabs, formerly reductivelabs.
we use it internally at EY for managing lots of things customer’s don’t interact with
they have a pretty vibrant user community

Cuttin’ Up with Chef

opscode has their own platform where people can share cookbooks
you can compose your recipes for your system based on the work of others
there’s a huge number of open source cookbooks available on GH, EY uses chef

Celebrate Your Product

devops is a proactive approach at covering the product lifecycle from an ops perspective

Delight Your Users

delivering your product on time w/ a better sense of reliability in the system
this makes end users happier, and

Enjoy Yourself

enjoy yourself, be a maker, an automator, and perhaps a devop
Thanks
