Continuous Integration (CI), Continuous Delivery (CD), and Continuous Deployment (CD) are interrelated processes that automate software delivery, each with distinct goals and methodologies. CI focuses on automating the building and integration of code changes, ensuring that they are consistent, repeatable, and available, while CD emphasizes automating the deployment and release processes to safely deliver software changes to production. Continuous Deployment automates the actual deployment of code to production environments once it passes quality checks, minimizing human intervention. Together, these practices aim to streamline the software delivery pipeline, allowing for faster, more reliable updates and features in production, with automation being key to reducing manual tasks and enhancing efficiency. The processes are supported by modern tools and platforms like Kubernetes and the Harness Platform, which facilitate scalable, agile, and safe software deployment across various environments.
