Continuous integration (CI) and continuous delivery (CD) are important to bring about a positive result to a company. This makes CI-CD an agile practice in many organizations and is being followed and adopted across the world.

In this article let us look at:

  1. Continuous Integration
  2. Continuous Delivery
  3. List of CI CD Tools

1. Continuous Integration

Continuous Integration or CI is the process of integrating the constant code into the Codebase. It makes small integration frequently because a few minor code changes are capable of producing fewer and unwanted results. The integrations are checked to look for errors that are done not by humans but by automation that is built into it. Continuous integration relies on many automation tools that include the code management systems and the CI servers. This speeds up testing, deployment, and software product packaging. It allows detecting early and eliminating the problems, which help to mitigate the integration issues. With constant code integration, the team is capable of fostering collaboration that lets developers deliver high-quality software quickly.

2. Continuous Delivery

Continuous delivery or CD is the method to deploy frequent and small changes in the software like UI enhancement, bug fixes, and feature improvements. CD starts when CI ends. CD includes staging and testing, and it also deploys the continuous integration code. CI is basically about the developer practices, and CD belongs to the operation realm. Introducing incremental changes has many uses because they are less troublesome as compared to the process of releasing any software upgrade in a single go. When continuous and minor changes are implemented, then it is makes troubleshooting and rollback easy. It also allows adding new features that meet the demands of the clients.

Like CI, CD is dependent on automated testing, regression, and monitoring performance that helps to identify the errors and look for any vulnerability in security when the software passes through the CI-CD pipeline tools. With both CD and CI, few changes will allow more targeted and precise tests that ensure speedy delivery of the best code quality to the end-user.
