What is CI/CD?
1. What is CI/CD?
So, what is CI/CD, and why is it a useful software development technique? Continuous integration and continuous delivery, which is what CI/CD stands for, is a software development practice that involves automating the process of building, testing, and deploying code changes. This allows developers to deliver updates to users more frequently and reliably. Let’s define each term. Continuous integration refers to the practice of frequently merging code changes into a central repository. This repository then undergoes automated builds and tests to ensure the code remains functional after each integration. And then there is continuous delivery, which is a method where teams produce software in short cycles and use processes that ensure the reliable release of software to production at any time. This helps minimize the risk of loss of service quality. For some companies, this means pushing releases to production several times a day. Now that you know what CI/CD stands for, let’s explore some of the benefits. For starters, CI/CD can help detect bugs sooner, which can prevent them from turning into larger problems later in the development cycle. For example, if all of your users have the same version of the application, developers can test updates on a percentage as small as 1%. Feedback can be used from that 1% to identify and fix any bugs or anomalies in the new update, so that when you roll the update out to the other 99% of users, very few bugs will be visible to them. CI/CD can also help improve code quality, because frequent integration and testing can encourage developers to write cleaner and more robust code. It can help enhance collaboration since teams work on a shared codebase. And finally, CI/CD can also help reduce the risk of regressions, because merging code frequently minimizes the chances of breaking existing functionalities.2. Let's practice!
