What is CI/CD in software development?

CI/CD (Continuous Integration/Continuous Delivery or Continuous Deployment) is a practice in software development aimed at automating the process of building, testing, and deploying software. The main goal of CI/CD is to accelerate development and improve the quality of the software product by automating tasks and implementing a continuous build-test-deploy cycle. The core concepts of CI/CD include Continuous Integration and Continuous Delivery.

This practice involves developers regularly merging their code into a shared repository (for example, a version control system like Git). After the code is merged, an automatic build and testing of the software is performed to detect conflicts and errors.

This practice ensures that the software is always ready for release, as the processes of building, testing, and deployment are fully automated. The software can be ready for release at any moment, and developers can release new versions immediately after successful testing. Continuous Deployment (CD) - is a practice that extends Continuous Delivery and involves the automatic deployment of new versions of software into the production environment after they have successfully passed testing.

The application of CI/CD allows for reduced development cycle time, improved software quality, decreased likelihood of errors in the product, and makes the software deployment process more reliable and efficient.
