What are the main principles of continuous integration (CI) and continuous delivery (CD), and how do they streamline software development and deployment processes?

Continuous integration (CI) involves automating the integration of code changes into a shared repository, verifying build integrity through automated tests, and providing feedback to developers. Continuous delivery (CD) extends CI by automating the deployment process, enabling frequent, reliable, and low-risk releases of software changes to production environments. CI/CD principles include version control, automated testing, build automation, deployment automation, and continuous monitoring, promoting collaboration, quality assurance, and rapid delivery in agile software development practices.
