DevOps: What, Who, Why
and How?

Let’s talk about a company you
might not think of as a tech
innovator

“Sysco, an acronym for Systems and Services
Company, is the world's largest broadline food
distributor; it has more than 600,000 clients in a wide
array of fields… The company operates
approximately 330 distribution facilities worldwide;
providing service to over 90 countries.”
Wikipedia · https://en.wikipedia.org/wiki/Sysco

Sysco was upgrading its ERP solution
• Standardize processes
• Improve operations
• Protect against outdated legacy systems
The project modernized hardware and infrastructure,
but stuck with existing ERP solutions
Tech Trends 2018 · Corless, de Villiers Garibaldi · Deloitte ·
https://deloitte.com/insights

A problem became apparent
12 upgraded operating
companies
• No significant
operating advantages
• Money already spent
60 non-upgraded
operating companies
• Should we spend
more?

Another concern…
• Competitors were modernizing as well
• Spending less than Sysco
• Focusing on simplifying customer experience

Here’s who confronted the problem
https://www.linkedin.com/in/wayneshurts/

Changes initiated by Wayne Shurts, CTO
Focus on the “secret sauce” present in the
customizations of the legacy ERP system
Reimagine applications around this using cloud
technologies and modern architectures
Work in an Agile framework embracing DevOps

“Our competition and our
customers expect to see things
they’ve never seen before in heavy
doses.”
Wayne Shurts, Sysco

“If you believe that the pace of change
in the world today will only accelerate,
then you need to move to not only a
new method but a new mind-set.”
Wayne Shurts, Sysco

What is DevOps?
The union of people, process, and products to enable continuous
delivery of value to our end users
An approach that aims at building, testing, and releasing software
quickly and frequently
A framework for managing work in teams of 3-9 members, which
breaks work into timeboxed sprints that are commonly 2 weeks long

Agile
Scrum

Compare: agile and DevOps
Agile
• Software development
approach
• Emphasis on small
dev teams
DevOps
• You don’t have to use
agile methods but…
• Emphasis on culture,
automation, cross-
functional teams
including IT, marketing,
support, sales

Scrum is an agile framework
• This can be used with DevOps
• Encourages daily face to face collaboration
• Focuses on delivering quickly
• Acknowledges emerging requirements
https://en.wikipedia.org/wiki/Scrum_(software_development)

What is continuous deployment?
A practice which begins by converting requirements into test cases
which initially fail
A practice of frequently merging all developer changes to a main code

Continuous which?
Continuous delivery
Every change is ready to
be deployed – when the
business chooses to
deploy
Continuous deployment
Every change is
automatically deployed

Compare: Continuous delivery & DevOps
Continuous delivery
• Set of practices to
standardize
deployments
• Includes validation and
feedback
DevOps
• Enables continuous
delivery

process, and products to enable

Who in your organization
should be involved in
DevOps?

Misguided approach:
We have a DevOps team who does
DevOps for us

Specialists can help you adopt and learn
to improve DevOps practices, but can’t do
DevOps “for you”

“Up until 2015 the DevOps team at SEEK
assumed full responsibility for all builds,
deployments and operational support for
our Hirer and Candidate sites.”
Andrew Hatch, Platform Engineering Manager, SEEK
Andrew Hatch · “Why We Don’t Need a DevOps Team” ·
http://bit.ly/2Fv7dFv

“It was not an easy job.”

“We had made rapid advances in our
delivery processes but we still faced torrid
nights on-call with software systems
straining under the sheer volume of
product being deployed to them.”

Measuring DevOps performance
• Throughput / tempo
• Deployment frequency
• Lead time for changes
• Stability
• Time to restore service
• Change failure rate
• Categorizations
• Elite
• High
• Medium
• Low
2018 State of DevOps Report · Forsgren, Humble, Kim · DORA
· https://devops-research.com/research.html

Misguided approach:
DevOps is Developers doing Operations
(instead of IT people)

Specialists are still needed in DevOps,
even in small organizations

If small teams provide autonomous support,
what would a specialist such as a DBA do?
• Tailor source control strategies for database code
to work best for the organization
• Automate testing and release of database code
with the right review and approval gates to produce
stable, safe deployments

If small teams provide autonomous support…
• Efficiently identify risky database changes which
require careful code review
• Quickly provision databases which mask or remove
sensitive data for new projects
• Optimize practices to reduce bugs and outages
caused by database code releases

DevOps involves everyone
Broad cultural change
• Break down silos: bring
Dev into Ops and Ops
into Dev
• Focus on continuous
delivery of value to end
users
Gain insights about end
users
• Marketing
• Sales
• Support

Why should your organization
adopt DevOps?

David Linwood’s “three lenses”
CEO
CIO / CTO
IT & Dev Managers / Team Leaders
The ROI of Database DevOps · Hilbert, Duggan, and Linwood ·
Redgate · https://rd.gt/2FHaUHD

Let’s oversimplify a bit
CEO - corporate vision, maximize value
CIO / CTO - strategic goals for IS
Managers - tactical approach

The CEO lens
• Lower cost
• Major failures are expensive
• Higher revenue
• Faster time to market than competitors
• Customer satisfaction

Why should CEOs invest in DevOps?
47% of CEOs reported to Gartner that they are
experiencing pressure from their board of directors to
transform their digital business
2017 CEO Survey · Kasey Panetta · Gartner

Building the right software helps companies gain
more market share than they can by mergers and
acquisitions
“Information Technology and Industry Concentration” · James
Bessen · Boston University School of Law · 2017

Software core to business operations does not “level
the playing field” between large and small firms. It
“tilts” the playing field in favor of those who use it
most effectively
“Information Technology and Industry Concentration” · James
Bessen · Boston University School of Law · 2017

The Developer Coefficient 2018 · Stripe and Harris Poll

The CIO lens
• Throughput of the department
• Ability to collaborate
• Quality of services to the customer
• How to hire and retain good staff
• Employee satisfaction

By 2020… “50% of the CIOs that
have not transformed their
capabilities will be displaced from
the digital leadership team.”
Gartner Predicts, 2016
Gartner Predicts · https://gtnr.it/2QTb40b

Why should CIOs invest in DevOps?
2017 Forrester Research survey
• 64% of respondents said their businesses are
dissatisfied with time to release new features to
customers
• Only 23% of enterprises are releasing at least
monthly
The Forrester Wave: Continuous Delivery and Release
Automation, Q3 2017

The Developer Coefficient 2018, Stripe and Harris Poll

The manager lens
• Team performance
• Number and impact of defects
• Recovering from failure
• Minimize the impact of failure on
the customer and the team

Why should managers invest in DevOps?
• DevOps uses measurable global outcomes
• DevOps can advance the rate of these outcomes
by setting goals universal to all teams
• This tears down the “wall of confusion” epitomized
by dev teams being measured by throughput, IT
teams being measured by stability
Accelerate, Forsgren, Humble and Kim, 2018

How can your organization
start implementing DevOps?

“If you are currently testing the Agile-
DevOps waters, it’s time to wade in. Be
like the explorer who burned his boat so
that he couldn’t return to his familiar life.”
