This CI/CD full course will help you understand what is a continuous integration and continuous deployment in detail. We will look at what is DevOps, what is CI/CD pipeline, what is Jenkins, how to build a CI CD pipeline with Jenkins, and continuous delivery vs continuous deployment.
Continuous Integration (CI) and Continuous Delivery (CD) (What Is CI/CD?)
CI/CD can bring about a positive impact on a company’s bottom line. For this reason, it is increasingly becoming a mainstream agile practice, being widely adopted by organizations across the globe.
What is Continuous Integration?
Continuous Integration involves the process of constant code integration into codebase. The aim is to frequently make small integrations, as minor code changes can produce fewer unwanted results. All integrations are checked for errors via build automation, with no human intervention.
Continuous Integration heavily relies on diverse automation tools, including CI servers and code-management systems, to speed up the development, testing, and packaging of software products. It enables early detection and elimination of problems, which greatly mitigates integration issues. Constant code integration also fosters collaboration among teams, allowing developers to quickly deliver high-quality software.
What is Continuous Delivery?
Continuous Delivery (CD) is the methodology of deploying small and frequent software changes, such as bug fixes, UI enhancements, and feature improvements. Basically, Continuous Delivery starts where CI ends. In essence, CD includes staging, testing, and the deployment of Continuous Integration code. While CI falls under developer practices, CD belongs entirely to the realm of operations.
Similar to Continuous Integration, CD relies on automated regression, testing, and performance monitoring to identify errors and security vulnerabilities when software traverses the CD/CI pipeline. With both Continuous Integration and Continuous Delivery, fewer changes enable more precise and targeted tests, ensuring the speedy delivery of top-quality code to end-users.
