Continuous integration, continuous delivery, and continuous deployment are essential practices adopted by agile organizations to meet the new demands of digital transformation. Ultimately, the goal is to accelerate development and test processes and get new code out to production fast. This slide deck focuses on sustainably flowing ideas into the hands of customers in the form of innovative digital capabilities and applications, and continuously improving the digital business with CI/CD.

Continuous Integration, Delivery and
Deployment: Accelerate Innovation and

2. What Exactly is Digital Transformation?
The realignment of, or
new investment in,
technology and business
models to more
effectively engage digital
customers at every
touchpoint in the
customer experience
lifecycle

3. “If it takes you years to create a bad-looking, outdated
application, while startups adapt to market needs in a matter of
weeks or months, you can guess who will win this race” –

4. Why a Devops Approach is Critical to Achieve
Digital Transformation
DevOps helps to
• Increase collaboration
between departments
• Increase deployment
frequency
• Improve quality
• Reduce cost on
development and
operations

5. Success Stories

6. What Do They Do Differently?
• Agile development
• Deploying smaller
changes frequently
• React fast – faster
feedback from real users

7. In devops, the entire process cycle is automated to
achieve continuous integration, continuous delivery
and continuous deployment.

8. Continuous Integration

9. • Integrate code early and often to the main
branch or code repository
• Goal: Reduce the risk of seeing “integration
hell”
• Getting started: Setting up automated testing
Continuous Integration (CI)

10. 1. Write tests
2. CI service to run tests automatically on every commit.
3. Integrate changes everyday.
4. Fix the build if broken.
5. Write tests for every new story

11. Continuous Delivery

12. • Making sure your code is always ready to release -
even if you are not deploying every change to
production
• Goal: Ship changes to customers early and often
• Getting started: Having a good CI culture in place and
set up continuous delivery pipeline.
Continuous Delivery (CD)

13. • Focus on releasing smaller bits frequently
• Easy to localize cause of problems
• Fail fast and fix fast
• Fewer defects
• Shorter defect lifespan

15. Continuous Deployment

16. • New changes pushed to the repository are
automatically deployed to production if they
pass the tests
• A radical approach
• Getting started: Having a good Continuous
Delivery culture in place

• Business use
cases

19. CI/CD With WSO2

20. • An organization may have an existing CI/CD
process
• WSO2 product-related development must
align with the existing CI/CD process
• Software delivery would need to include both
WSO2 middleware and application changes
CI/CD for WSO2 Products

21. Things To Consider
• Solution and deployment
architecture
• Infrastructure
• Configurations
• Extensions and external
libraries
• Tools
• CI/CD pipelines for
deployable artifacts
• Product updates

31. • To truly embrace digital transformation,
adopting the ‘continuouses’ is no longer a
‘nice-to-have’
• With CI,CD and CD, you can transform and
accelerate the software delivery pipeline
• Speed to market can break a company or
enable it to survive and thrive into the future
