Deploying applications in minutes, a huge issue during the present time of rapid-fire software development. Continuous Integration (CI) and Continuous Delivery/Deployment (CD) are now essential to accelerate development cycles, enhance code quality, and eliminate deployment risk. Tools for CI and CD are the central part for software development process automation in a way that allows teams to test, integrate, and deploy code at speed. From a solo developer, corporate to start-up, the right CI/CD tool will transform your process.
This guide explores the best tools for CI and CD, their features, benefits, and how they fit into modern development pipelines. By the end of this article, you’ll have a clear understanding of the tools for CI and CD available and which one best suits your project needs.
Understanding CI/CD: A Quick Overview
Before diving into the tools, it’s important to understand what CI/CD is and why it matters.
What is Continuous Integration (CI)?
Continuous Integration (CI) is a method of software development where the code of developers gets committed into one common repository constantly. Their code gets tested by a build process and a test process automatically so that bugs are detected in early stages of the development process.
What is Continuous Delivery and Continuous Deployment (CD)?
Continuous Delivery makes the software deployable at any moment. Code changes are tested automatically and are waiting for manual approval to deploy.
Continuous Deployment goes one step further—each tested change is deployed automatically to production without human intervention.
