What is DevOps?
DevOps is the union of people,
process and products to enable
continuous delivery of value to our
end users

What are we
trying to solve?
Ship the right thing at the right time
Consistency and repeatability
Minimize downtime and
maximize recovery

How do we do
this?
Establish best practices
Identify stakeholders
Implement tools

Defining common
DevOps terms
Continuous integration
Ensuring new code follows patterns and doesn’t
break the build
Continuous delivery/deployment
Ensuring new code is pushed to hosting
environments
