Enabling Continuous Delivery via DevOps Principals

1. CONTINUOUS APPLICATION DELIVERY(CAD)
- How DevOps Culture Enables CAD
- DevOps & OpsDev
- CAD Maturity Model

2. Continuous App Delivery – Follows DevOps Principles
Break Silos
Agility only work when we work as
ONE TEAM
Fail Fast, Learn Fast!
Reward Failures & Encourage to Fail Fast
- Be Agile NOT FRAGILE
Automation is the Key Transparency

4. Continuous Application Delivery - Application Maturity Scorecard
AD-HOC MANAGED DEFINED OPTIMIZED
AGILE DELIVERY
 Teams rely mainly on manual
testing after development is
complete to find defects.
 System integration is painful and
happens after development on a
module is completed.
 Provisioning production-like
integrated testing environments
is expensive and manual.
 Deployment process is manual
 Developers, testers, operations,
and management have goals
that bring them into conflict.
 Change management is ad hoc
or heavyweight and often
circumvented or ignored.
 Clear product ownership and
chain of responsibility are in
place.
 Change management controls
are implemented, including a
process to detect unauthorized
changes with consequences
defined.
 Business participates fully and
regularly in development
activities and decisions related
to delivery.
 There is some automated
acceptance testing.
 Production-like testing
environments are available for
projects early on.
 There is some scripting to
reliably and repeatedly configure
environments and build
packages from version control.
 Teams practice trunk-based
development with continuous
integration of all changes.
 There are enough automated
tests that critical defects are
detected and prevented fast and
automatically.
 Provisioning of environments is
fast and automated.
 No work is considered done until
it has passed automated unit
and acceptance tests associated
with the Job
 Testers are not primarily
focused on regression testing.
 Database changes are bundled
with versioned releases
 History of release is art-factored
and seamless rollback’s
 Self-Serviceable tools &
frameworks are provided to
Development Teams for
seamless App Lifecycle
management (incl. Build &
Deployment)
 All new requirements describe
how the value of the feature will
be measured.
 Product teams are responsible
for implementing metrics to
gather this data through
techniques.
 Systems are architected with
continuous deployment in mind,
supporting patterns such as dark
launching to decouple
deployment from release.
 Database changes are
decoupled from application
deployments.
