Travis CI introduction
Travis CI is a hosted and automated solution for CI builds. Travis CI uses an in-application configuration file that uses YAML (http://yaml.org/spec/1.2/spec.html) syntax, which we will go over in more detail later in this chapter. Since Travis CI is hosted in the cloud, it therefore has the advantage that it can quickly be used in other environments and different operating systems without us worrying about setup and installation. This means that Travis CI setup is much faster than Jenkins.
Comparing Travis CI and Jenkins
Jenkins is a self-contained and open source automation server that is customizable and requires setup and configuration at the organization level. Remember, in the Jenkins CI chapters we spent some time installing Jenkins on Windows, Linux, and macOS. We also had the ability to configure Jenkins however we wanted. While this is great for software companies with dedicated teams in operations, DevOps and more, it is not as great for open source projects...
