Continuous Deployment

slide-38
SLIDE 38
  • Techniques such as automated testing,

continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead.

Professor Wikipedia says:

…boring

Continuous deployment is about developing and deploying in short, rapid increments.

Benefits for Developers:

  • A simple, easy-to-learn workflow
  • No release process
  • Frequent feedback
  • Low-risk, low-stress ships
  • Merge conflicts become trivial
  • Ownership, agency, quick wins, and responsibility
