CI vs. CD vs. GitOps vs. State Management: What's the Real Difference?

[CI and CD are not about tools but processes: CI validates code changes continuously, while CD extends this with deployment to production and ongoing state management, with CI being a subset of CD]1:01
Key Takeaways:
• Continuous Integration (CI) involves regularly merging code into main branches with automated testing to validate changes, ensuring code correctness and reducing integration risks 2:01-2:46
• Continuous Delivery (CD) goes beyond CI by including regular deployment to production, requiring validated, working code—making CI a necessary foundation 3:44-4:25
• One-shot actions (e.g., building images, running tests) are automated via workflows (e.g., GitHub Actions, Jenkins), while State Management ensures desired states are maintained in production through continuous drift detection and reconciliation 6:00-8:41
• GitOps tools like Argo CD and Flux manage state by storing desired states in Git and reconciling them with actual states in clusters, though they are not CD tools themselves 9:42-10:49
• Visualization of CD processes is challenging when workflows and state management tools operate independently—true observability tools are better suited for monitoring actual, evolving states 17:00-19:07
The video concludes that CD processes should be split into one-shot actions and continuous state management, with visualization split accordingly—observing workflow outcomes and system states separately for clarity.

welcome to the's toolkit the channel where activities can be considered at the same time both one shot and State Management at least until we observe [Music] them today I want to answer a set of questions I get fairly often people ask me to compare GitHub with cicd or to explain the difference between CI and CD at other times I hear people talk about those terms with confidence yet often with misunderstanding of what those are to make things more complicated tools tend to have misguided names that often make the situation even more complicated so today's session will explain the difference between continuous integration or CI continuous delivery or CD and gups we will add State Management to the mix and we'll go not only through processes and activities related to those terms but also try …
