What are the differences between CI and CD?

CI stands for Continuous Integration, while CD can refer to Continuous Delivery or Continuous Deployment. CI focuses on automating the integration of code changes from multiple contributors into a shared repository. CD, on the other hand, automates the delivery of these integrated changes to production or staging environments.

Can you explain how CI works?

Sure! In CI, developers frequently commit code to a shared repository. Each commit triggers an automated build and testing process, ensuring that new changes integrate well with the existing codebase and that any issues are caught early.

What about Continuous Delivery?

Continuous Delivery is an extension of CI. It ensures that the code is always in a deployable state, allowing for frequent releases to production. It involves automated testing and staging processes to ensure quality before deployment.

How does Continuous Deployment differ from Continuous Delivery?

Continuous Deployment goes a step further by automatically deploying every change that passes the automated tests directly to production, without manual intervention. This means that every change is live as soon as it's ready.
