Jenkins-Worker: SSH or JNLP Connection?

jenkins ssh jenkins-plugins jnlp

Java Web Start -- and the underlying Java Network Launch Protocol (JNLP) is the recommended mode of connection for windows agents.jenkins.wiki.io
SSH is recommended for Linux agents

The Pros and Cons don't matter if both are recommended for different platforms.

jenkins ssh jenkins-plugins jnlp

We are only using SSH, mainly because in a corporate setting:

asking for the JNLP port to be opened on the agent server (agent being the new name for slave in Jenkins)
any query to another server should use an authenticated flow (like SSH with a key, or an account username/password)

Plus we can add to the Launch method configuration various JVM Options to monitor the GC and other memory parameters.
