What is the difference between Continuous Integration, Continuous Delivery, and Continuous Deployment?
- CI: Automatically integrate code changes with testing
- Continuous Delivery: Code is always ready for production deployment
- Continuous Deployment: Every change automatically goes to production
- Each builds upon the previous practice
- 💡Think about the level of automation and human involvement
- ⚠️Conflating Continuous Delivery and Continuous Deployment, failing to clearly distinguish the manual vs. automatic production deployment step.
- ⚠️Omitting the critical role of 'automated testing' as a core component and enabler of Continuous Integration.
- ⚠️Missing the essence of 'always deployable' for Continuous Delivery, implying that code is merely tested, not fully prepared for release.
- ⚠️Not emphasizing the 'no human intervention' aspect of Continuous Deployment, suggesting a manual gate still exists for production release.
- ⚠️Failing to explain the sequential and hierarchical relationship, making it seem like unrelated practices rather than progressive stages.
