Can you explain the principles and purpose of continuous integration and deployment processes in software development?

Continuous integration and continuous delivery (CI/CD) are processes that automate the building, testing, and deployment of software.

• Continuous Integration (CI) involves frequently merging code changes into a shared repository, followed by automatic build and test runs. This helps quickly identify errors and maintain code quality.
• Continuous Delivery (CD) automates the process of deploying applications to various environments (testing, staging, production). It enables faster releases and reduces manual deployment risks.

Example: each commit in the repository triggers a pipeline that builds the app, runs tests, and automatically deploys a new version to a test server.

This approach accelerates development cycles, improves quality, and ensures reliable releases.
