Continuous Integration (CI) and Continuous Delivery/Deployment (CD) are key components of a CI/CD pipeline in DevOps, allowing for automated building, testing, and deployment of code changes to enhance efficiency and maintain code quality. The CI stage involves multiple developers working collaboratively, frequently integrating code changes, which are validated through automated builds and tests. The CD stage focuses on automating the release process with human intervention required for deployment, ensuring the codebase is always ready for production. Continuous Deployment automates the entire process, deploying applications automatically post-testing. The text details setting up a CI/CD pipeline using n8n workflows with platforms such as GitHub, GitLab, TravisCI, and CircleCI, and offers insights into using Telegram and GitHub for deployment, showcasing the benefits of CI/CD in reducing manual efforts and accelerating feature delivery.
