CI/CD tools are essential in modern software development, automating the building, testing, and deployment of software to enhance development speed and code quality. Continuous Integration (CI) involves the frequent merging of code changes, with automated builds and tests to catch integration issues early, while Continuous Delivery (CD) automates code preparation for release, and Continuous Deployment goes further by automatically pushing tested changes to production. These practices improve collaboration, reduce deployment risks, and enhance productivity by freeing developers from manual processes. Tools like Jenkins, GitLab, CircleCI, and Harness facilitate these processes, each offering unique capabilities such as Harness's integrated DevOps platform, which provides streamlined pipelines, minimal scripting requirements, and robust governance features. CI/CD is a core component of DevOps, a broader philosophy aimed at fostering collaboration between development and operations. Security is a critical aspect of CI/CD, with measures like secure code analysis and access control integrated to protect against vulnerabilities. Eric Minick, an expert in software delivery, contributes to the development of Harness, a platform designed to optimize CI/CD processes.
