CI/CD

Continuous Integration and Continuous Delivery (CI/CD) is a set of practices that enable developers to build, test, and deploy software faster and more reliably. CI/CD aims to automate the software delivery process through an automated pipeline.

In CI/CD, developers integrate their work frequently, usually multiple times a day. Each integration triggers an automated build and test process to catch errors quickly. Passing builds are automatically deployed to testing or production environments, ensuring fast delivery of features to users. For example, a CI/CD pipeline may automate building code, running unit tests, security scans, integration tests, and deploying to a staging environment after each code commit. The pipeline shifts code changes left into lower environments to catch issues early. Once properly tested, changes can be promoted automatically to production. Overall, CI/CD improves software quality and accelerates delivery by standardizing and automating the build, test, and deploy steps.
