20 AWS Cost Optimization Moves That Still Pay Off

Building Jenkins Infrastructure Pipelines
Jenkins allows you to automate everything, from building and testing code to deploying to production. Jenkins works on the principle of pipelines, which can be customized to fit the needs of any project. After installing Jenkins, we launch it and navigate to the web interface, usually available at http://localhost:8080. On the first launch, Jenkins will ask you to enter a password, which is displayed in the console or located in a file on the server.
