Travis CI is critical for Linux and macOS CI tests for the Powershell module. Travis runs the same tests we run in AppVeyor in parallel.
We leverage Python for tools like awscli and cfn_flip so they are able to be leveraged during CI tests.
We use AppVeyor for unit and integration testing of the Vaporshell module for Powershell, as well as deployment on successful tests via PSDeploy
