What is the difference between continuous integration, continuous delivery, and continuous deployment in DevOps?

Continuous Integration, Continuous Delivery, and Continuous Deployment are essential concepts in DevOps methodologies.

Continuous Integration (CI) involves automatically integrating code changes from multiple developers into a shared repository multiple times a day. The focus of CI is to detect and address integration issues early in the development process.

Continuous Delivery (CD) extends CI by automatically deploying code changes to production-like environments for testing. This ensures that the code is always in a deployable state and can be released to production at any time.

Continuous Deployment (CD) takes the automation a step further by automatically deploying every code change that passes automated tests to production. This approach minimizes manual interventions and accelerates the release cycle.

Overall, the key difference lies in the extent of automation and frequency of deployments between CI, CD, and CD in DevOps practices.
