3EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
This is not a tech talk
4EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
This is an organizational change talk
5EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
But to make those organizational changes…
6EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You need to embrace modern technologies
7EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Just like when we move to better engines, phones, etc
8EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Let’s look at thehistory of our apps
9EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
From 10 years ago
10EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Or perhaps 2 days ago
11EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Consider astandard monolithic
application

13EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
How do you scale it?

15EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
http://cantina.co/monolithic-architecture-doesnt-scale/
16EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
So what to do?
17EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
It’s not all about scale
18EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
But also aboutseparation of concern
19EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Microservices

21EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Everything isloosely coupled
22EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Enables parts to be fixed, updated and worked on…
23EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Independently!
24EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Traditional apps will not
• Drive your organization forward
• Allow you to innovate quickly
• Enable your staff to develop new skills with modern tools
25EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
So what?
26EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Some might say…
27EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
We're just anIT organization,
not the line of business
28EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
We're just anIT organization,
not the line of business
29EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You're the machinery, the glue, the conduit
30EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You make things work
31EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You help drive thebusiness forward
32EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
How about making your business more profitable?
33EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
But first…
34EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Where do we start?
35EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Let’s talk about some real pain points in your orgs
36EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You can't wait 6 monthsfor a feature/upgrade/bug fix/etc
37EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Solve configurationdrift issues quickly
38EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Know what’s wrong, where and why. Not who!
39EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Last and most importantly, improve team communication
and collaboration
40EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Let’s have a look at somepopular languages/frameworks
41EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Python 2.7
JRE 8
NodeJS 0.12.2
Haskell 7.8.4
Go 1.4.2
Rust 1.0.0-beta.3
Ruby on Rails 4.2
42EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Will they solve your 6 month cycle? Your config drift? Your errors?
43EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Most probably not
44EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
How long would it take your organization to deploy a change
that involves just one single line of code?

56EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
What is DevOps?
57EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
An idea or collaborative culture/philosophy between
technical teams
58EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Unified processes and tools for faster end-to-end delivery of quality
software
59EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
It’s all about removing nonvalue-adding wastes
60EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Make the timeline from customer order to cash in your bank as
short as possible
61EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
DevOps practices and IT performance impact

62EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Enabling IT to work efficiently leads to
• 30x more frequent production deployments
• Deployments performed 8000x faster(I know, crazy number)
• 2x higher success rate on deployments
• 12x faster fixing of issues
63EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Enabling IT to work efficiently leads to
• 2x more likely to exceed profitability, market share and productivity goals
• 50% higher market capitalization growth over 3 years
64EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Wait a minute…
65EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
You get all that from modernizing your apps?
66EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Of course not, you can't buy efficiency
67EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
But modernizing your apps enables you to make smarter choices and
change your processes
68EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Modernized apps will
• Give your teams smaller focus areas
• Enable your teams to innovate faster
• Let you practice Kaizen
69EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
The word Kaizen is Japaneseand means
Continuous Improvement
70EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
So should youreally do this?

Let's start with
infrastructure as code
77EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
What do we define as infrastructure?
78EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
79EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
80EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
81EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Deploy, monitor and connect together all the pieces needed to run services for the organization
• Processes and tools for faster end-to-end delivery of quality services
• Automation comes built-in
Why define infrastructure as code?
82EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Desired state specified in text files
• Autonomic (self-corrects to desired state)
• State should be known through monitoring
• Remove snowflake servers
How do we do this?
83EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Easy to read and edit
• Shareable
• Can use standard version control like Git or SVN
• Becomes executable documentation
Why store them in text files?
84EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
node 'www2' {
class { 'apache': } # use apache module
apache::vhost { 'awesomewebsite.com': # define vhost
port => '80',
docroot => '/var/www/html'
}
}
Simple example
85EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
user { root:
ensure => present,
password => '$ecretP@ssw0rd',
}
Change root password
86EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Manually configured environments are like a house of cards in a china
shop
- Neal Ford
87EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Deploying, provisioning and scaling automatically is virtually impossible if every server is unique
• Adds friction between the requestor and the deployer
• Mistakes happen
• We're all human
Snowflake servers
88EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
What can happen if you don't treat infrastructure as code?
89EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Up to 60% of failures are caused by human error,
not hardware failure
90EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Example - Knight Capital Group
https://infocus.emc.com/wp-content/uploads/2012/08/KCG.jpg
91EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Manual deployment of new trading software
• 7 of 8 servers correctly updated
• Old function still alive on the 8th server led to…
Knight Capital Group - What happened?
92EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
$440 million lossin 45 minutes
93EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
So
94EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Treat your infrastructure as code
95EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Self documenting infrastructure
• You now have source code for how anything in your datacenter is setup
• Executable documentation
Recap of the benefits
96EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Alright
97EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
Then what?
98EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY

106EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• And by smartly we mean cooperatively between Devs and Ops
• Will help operators understand what's running and happening in the infrastructure
• Will give developers insight into the underlying infrastructure and the way it behaves under load
Use these tools smartly
107EMC CONFIDENTIAL—INTERNAL USE ONLYEMC CONFIDENTIAL—INTERNAL USE ONLY
• Start talking about it
• Choose low-hanging fruit
• Learn, make wrong decisions, learn again
• Involve the broader team– Give books, presentations, blog posts etc.
So how do we get started?
