A Short Story: Meet
Gina, She’s a Developer
• Gina loves to code
• Her focus:
• Extending products
• Building new
products
• Fixing Bugs

Meet
Jose, He’s
an
Operation
s Lead
• Jose is passionate about keeping the production environment
available to all customers
• His focus is:
– Ensuring the production environment hits 99.999% uptime
– Ensuring that new code does not break the existing
production code
– Reducing risk that the production environment will go down

Meet the Challenge: Consumer Needs
• Consumer needs are changing faster with
greater demand on digital services
• The number of digital services is growing
exponentially
• Speed to market is critical
• The barrier of entry into Digital Services has
never been lower

Developers and Operations are two different
groups with different responsibilities
Throwing code over the wall
Limiting the number of releases that can
happen
Reducing the ability for the company to adjust
to consumer trends
Teams are in silos with a conflict of interests
Meet the problem:
Conflict of interests

Meet the Hero Team: DevOps
Bringing Developers
and Operations
together
Combining the
strengths of two
worlds
Small code blocks
vs large
Share
Responsibilities

What is DevOps?
Integration of Develop and Operations into one team
One team has better communication and
collaboration
Productivity is improved through automating testing
code, infrastructure, workflows and anything else
that can automated
Continuously measuring application performance

How DevOps Works
Code is written in very
small chunks vs large
builds
Deployments happen
in days/hrs vs
weeks/months
Development
environment is
identical to production
Rapid iteration
improves speed to
react to market needs
Developing
Configuration
Management Code to
build Infrastructure at
Scale
Realtime Application
Performance
Monitoring to know
the impact each code
change makes

What does this all mean?
New
Mindset
New Tools
New Skills
Preparing
for fast
paced
world

New Tools
Code Development
Testing Code (Jenkins)
Tracking Code & Configuration Management Changes
(GitHub)
Code Deployment (Chef, Puppet or Saltstack)
Managing Code on Scalable Servers
Tools to monitor production application and environment
(System Logs, Application Logs, New Relic)

Faster time to
market
Leveraging
Automation to
improve reliability
of infrastructure
More focus on
improving the
business
Benefits of DevOps

The end of the Story:
Happy Customers
• Faster to Market
• Align Outcomes
with Business
Goals
• Exceed Customer
Expectations
• Beat Competitors

What is DevOps: Summary
• Innovate Faster
• More Responsive to Business Needs
• Better Collaboration
• Better Quality
• More frequent Releases
• New Mindset + New Tools + New Skills =
DevOps

Challenges Azure Helps with
• Service Level Agreements
on Apps
• Data Sovereignty
• Test Criteria
• Monitoring of Apps
• Iteration of Apps
• Azure is An Open Platform

Build Azure the Way you Want it
• Yes, there are
Microsoft tools you
can use
• But there is also much
more
• Example: Linux can be

• Add VMs
• Even control when the VM runs
(Auto-Shutdown and Auto-Start) to
manage costs
• Azure Active Directory used for
Authentication for users and groups

Continuous Integration
• Visual Studio Team Services
• Continuous builds on new,
checked in code
• Ability to switch to Open Source
solutions (such as Jenkins)
• Focus on testing code in small,
consumable chunks

Continuous Feedback
•Live, Performance

The Azure ROI
Provide a set of tools that provide DevOps teams
to offer consistent, testable and scalable
environments to build and deploy applications

DevOps for Legacy Systems

Topics
What is Legacy
Why is it a
Challenge
How can DevOps
and Legacy work
together?

Wikipedia: What is Legacy?
In computing, a legacy system is an old method,
technology, computer system, or application
program, "of, relating to, or being a previous or
outdated computer system." Often a pejorative
term, referencing a system as "legacy" means that
it paved the way for the standards that would
follow it. This can also imply that the system is out
of date or in need of replacement.

Legacy Components

Problems with Legacy
• Hard to maintain, improve and expand
• Systems run on old hardware
• Run on older operating systems
• Integration with newer systems may be difficult
• Developers of legacy systems are ”aging out” and retiring
• Often, few people understand how the legacy system
actually runs

Today’s Big Problem
• Bi-Model IT – half of the team
working on cool, modern
solutions and half keeping older
systems running
• You are not alone

Solution to Legacy
Organization Interactions Automation

Organization
• Experiment
• Be more collaborative
• Blame Free
• Distribute Authority

Interactions
• Waterfall Process vs. Agile
• Small Batches
• Focus on Flow

Automation
• Focus on outcomes
• Remove legacy bottlenecks
• Improve speed to market
• Business value focus
• Reduce friction through self-service
