CI/CD stands for Continuous Integration and Continuous Deployment. It’s a way to automate the software release process.

Continuous Integration (CI): Every time a developer pushes code to the shared repository, an automated process runs. It builds the code. It runs tests. It checks for errors. This catches bugs early, before they reach users.

Continuous Deployment (CD): If the code passes all tests, it is automatically deployed to production. No human needs to press a button. The new version goes live automatically.

Without CI/CD, deploying software is scary. You have to manually run tests. You have to manually copy files to servers. You might forget a step. With CI/CD, it’s consistent, reliable, and fast. You can deploy dozens of times per day.
