Tentacle is a cross-platform file transfer protocol that aims to be secure and easy to use. The client and server are designed to be run from the command line or called from a shell script. Secure file transfers to and from the server are supported.
The Orchestrator server is responsible for distribution and launch of simple apply/rollback shell scripts in a particular order across multiple servers . If for any reason deployment is failing at a particular stage the process will stop and you can rollback any changes done until then.
In case you want to deploy your code or just call your preferred DSC client to apply the configuration locally the Orchestrator can be a handy tool.
