 Fusing of software development (Dev) with IT operations (Ops)
 A maturing of the agile software development methodology
 DevOps unites developers and IT operations to release high quality code into
solidly performing environments more rapidly than is possible with traditional
developer-to-ops handoffs.
 Solves a basic problem with agile methodology: Producing new code is of little
use if it cannot be deployed on reliable infrastructure.
 Growing in popularity: 63% of developers have implemented DevOps.*
 Faster code: High-performing DevOps organizations can ship code 30 times
faster with 50% fewer failures.*

Production
 A division between:
 Developers, who write the code, and
 Operations personnel, who are responsible for making sure the code is running
acceptably for end users.
 The groups can be quite distant from one another.
 Other stakeholders, such as line-of-business managers, compliance staffers, InfoSec, and
others, are also involved but generally removed from the software development-todeployment loop.
 The process tends to be sequential:
 Integration of new code into existing applications is done one release at a time.
 Operations methodically places newly integrated code into production.

 DevOps is a solution to the
slow, sequential approach:
 Unifies development with the
release process .
 Pulls all the participants into a
closer loop of collaboration and
cooperation.
 The pace of software releasing
can pick up significantly.
 The key concept of DevOps is
“continuous”.
 Integration, QA and deployment
go on continuously, perhaps
even several times a day.

 Hypothetical 10 person development and ops team
 Assuming a 2,000 hour work year and a fully burdened labor rate of $65 per hour,
the results are striking:
 Some weekly activities go up in hours spent (often for the good).
 But, time savings result in savings of $84,500 a year.
 Savings = 7% of the team’s $1.3 million annual budget.

 Deploying Changes – With continuous change built into the cycle, DevOps helps save time
spent on application and database configuration and infrastructure updates.
 Infrastructure Management – DevOps reduces the handoffs between developers and
infrastructure managers, in turn cutting the amount of time devoted to managing
infrastructure in response to software changes.
 Support – With support people continuously looped into the development cycle, DevOps
makes it possible for problems to be identified and solved before they can make trouble.
 Communication – The DevOps approach, assuming the right platform is in use, builds
efficient communication amongst all stakeholders right into the development and
deployment process.
 Firefighting – With support and infrastructure on the same page as developers, the DevOps
approach reduces the number and intensity of situations where mission-critical apps go
down – as well as the ensuing scramble to recover a system within recovery time objectives
(RTOs).

 Infrastructure Improvements –DevOps enables team members to spend more
time on improvements to the infrastructure that supports the business:
 Testing processes and recovery plans
 Reducing the number of application failures while also tightening recovery
time
 Self-Improvement – DevOps frees more staff time for training, reading and
continuing education.
 Brainstorming and “doing nothing” Some of the best technology innovations
come from just this kind of downtime. DevOps reduces stress, system failures and
fire drills, enabling team members to think.
 Thinking pays off for the business.

 DevOps involves collaboration between developers and operations teams:
 Not an intuitive combination
 Each group has a distinct culture, a different set of incentives, as well as differing
background and training in most cases.
 Getting DevOps to work is as much an exercise in cultural change management as
anything else.
 Tooling helps. The right DevOps platform, used the right way, can make a big difference in
the ROI outcomes:
 Choreography between the people, the tools and the culture
 Shared goals and metrics amongst DevOps team members
 Benefits of DevOps become noticeable when team members do the work and make it a
reality.
 Everyone becomes more productive and agile.
 When a developer, tester, product manager and system engineer all see improvement in
the qualities of work lives, delivering great results, this way of working becomes the
norm or the work culture.


The only way to ensure that every developer, tester, system engineer is a high performer is to make sure
they get early and instant feedback:
 When a developer pushes code into code repo, he or she gets immediate feedback on the code.
 For a product manager, it means ability to create a sandbox to show the new feature to business on
day one for their feedback.
 System engineers can simulate a new feature in production environment while it is still in
development.

There are three aspects to this:
 Ongoing intelligence of code in development - This requires the use of development and operational
tools that are instrumented to generate metrics.
 Operational intelligence ensures that all DevOps team members get all this feedback across all
functions and roles in a single dashboard. Everyone can see it and act upon it as needed.
 Analytics and an automated dashboard provide real-time insight to the entire team across roles so
that they can get early and instant feedback for high performance.


With DevOps, collaboration has to be seamless across both Dev and Ops teams and the entire application
delivery value chain:
 Set up automated processes and systems for Integrated Configuration Management, Continuous
Integration, Automated Testing, Deployment Planning, Infrastructure Provisioning, Continuous
Deployment, Integrated Change Management and Monitoring.
 Integrate these tools to create a full stack DevOps platform
 Common tooling so team members don’t need to hand off artifacts between teams and risk
creating gaps
 Testing and deploying application code and infrastructure code in the same pipeline

The problem arises when developers patch fix the DevOps tool chain:
 Things can work well at first with a patch-built tool chain, but as scale and complexity grows, this
starts breaking.
 Scale and complexity typically trend up with the success of the Continuous Delivery model.
 Multiple deployments every day are not uncommon as new features are released.

As DevOps flourishes, the business gets used to more innovation from IT and the cycle grows more
intense.
 This is known as having a rapid innovation culture. It arises when DevOps best practices and the tool
chain are one.
 Having a fully integrated DevOps tool chain with one-click access to the entire application lifecycle
has proven to help teams scale effortlessly.
16

16.
 Applications have to morph with business needs:
 An application might start out running in a public cloud but very soon needs to move
behind the firewall or have the back end moved to a big data platform.
 When DevOps teams start developing applications, there has to be target environment
in mind, but it is very important that the team be able to have flexibility with dev and
run environments to morph as needed.
 E.g., An app may use a public PaaS but tomorrow it may need to use an internal private cloud.
 E.g., A mobile app front end id connected to a big data platform back end.
 It is essential to have the flexibility to develop/test/run in any environment seamlessly:
 Teams can provision infrastructure and tool chain anywhere and carry applications stack
across these environments.
 Elastic provisioning of systems for Contiguous Integration, automated
testing, deployment and production environments
 Projects and profiles can be tracked and versioned so that previously configured systems
can be recreated with a single click to test new code easily, revert to previous
configurations, and compare system versions.
 A fully searchable repository is available to facilitate standardization and reuse.
17

17.
 DevOps has tremendous potential to drive financial returns and strategic advantage:
 By combining developers and IT operations in coherent, closely coordinating
teams, DevOps speeds up the delivery of high quality software.
 From an ROI perspective, this acceleration of software can either cut IT costs or enable a
greater, more business-friendly productivity in IT.
 At the same time, rapid releasing of good code can unlock market value and raise
revenue – beating back competitors who are swarming after the same customers.
 Getting to ROI with DevOps is not simple, however. It takes a combination of the right tooling
and a commitment to organizational cultural change.
 Both factors must be in action for DevOps to flourish and deliver financial benefit to the
business.
